D22.07 - Sampling, Analysis, Management of Asbestos, and Other Microscopic Particles

SIGNIFICANCE AND USE
5.1 This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere for asbestos structures. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be identified. Most of the airborne asbestos fibers in ambient atmospheres have diameters below the resolution limit of the light microscope. This test method is based on transmission electron microscopy, which has adequate resolution to allow detection of small thin fibers and is currently the only technique capable of unequivocal identification of the majority of individual fibers of asbestos. Asbestos is often found, not as single fibers, but as very complex, aggregated structures, which may or may not also be aggregated with other particles. The fibers found suspended in an ambient atmosphere can often be identified unequivocally if sufficient measurement effort is expended. However, if each fiber were to be identified in this way, the analysis would become prohibitively expensive. Because of instrumental deficiencies or because of the nature of the particulate matter, some fibers cannot be positively identified as asbestos even though the measurements all indicate that they could be asbestos. Therefore, subjective factors contribute to this measurement, and consequently, a very precise definition of the procedure for identification and enumeration of asbestos fibers is required. The method defined in this test method is designed to provide a description of the nature, numerical concentration, and sizes of asbestos-containing particles found in an air sample. The test method is necessarily complex because the structures observed are frequently very complex. The method of data recording specified in the test method is designed to allow reevaluation of the structure-counting data as new applications for measurements are developed. All of the feasible specimen preparation techn...
SCOPE
1.1 This test method2 is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of asbestos structures in ambient atmospheres and includes measurement of the dimension of structures and of the asbestos fibers found in the structures from which aspect ratios are calculated.  
1.1.1 This test method allows determination of the type(s) of asbestos fibers present.  
1.1.2 This test method cannot always discriminate between individual fibers of the asbestos and non-asbestos analogues of the same amphibole mineral.  
1.2 This test method is suitable for determination of asbestos in both ambient (outdoor) and building atmospheres.  
1.2.1 This test method is defined for polycarbonate capillary-pore filters or cellulose ester (either mixed esters of cellulose or cellulose nitrate) filters through which a known volume of air has been drawn and for blank filters.  
1.3 The upper range of concentrations that can be determined by this test method is 7000 s/mm2. The air concentration represented by this value is a function of the volume of air sampled.  
1.3.1 There is no lower limit to the dimensions of asbestos fibers that can be detected. In practice, microscopists vary in their ability to detect very small asbestos fibers. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.  
1.4 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 10 % coverage of the collection filter by particulate matter.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropri...

SIGNIFICANCE AND USE
5.1 This test method is applicable to the measurement of airborne carbon nanotubes in a wide range of ambient air situations and for evaluation of any atmosphere for carbon nanotube structures. Single carbon nanotube structures in ambient atmospheres have diameters below the resolution limit of the light microscope. This test method is based on transmission electron microscopy, which has adequate resolution to allow detection of small thin single carbon nanotubes and is currently a reliable technique capable of unequivocal identification of the majority of nanotube structures. Carbon nanotubes are often found, not as single carbon nanotubes, but as very complex, aggregated structures, which may or may not be aggregated with other particles.  
5.2 This test method applies to the analysis of a single filter and describes the precision attributable to measurements for a single filter. Multiple air samples are usually necessary to characterize airborne nanotube structure concentrations across time and space. The number of samples necessary for this purpose is proportional to the variation in measurement across samples, which may be greater than the variation in measurement for a single sample.
SCOPE
1.1 This test method is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of carbon nanotubes and carbon nanotube-containing particles in ambient atmospheres.  
1.1.1 This test method is suitable for determination of carbon nanotubes in both ambient (outdoor) and building atmospheres.  
1.2 This test method is defined for polycarbonate capillary pore filters through which a known volume of air has been drawn and for blank filters.  
1.3 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 25 % coverage of the collection filter by particulate matter.  
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 This practice applies to response actions for all types of asbestos-containing materials, including surfacing materials, thermal systems insulation, and miscellaneous materials, whether friable or not, regardless of the quantities involved and the reason for conducting the response action.  
5.1.1 Abatement for the purpose of removing asbestos-containing materials or encapsulating or enclosing them, regardless of the engineering controls and work practices used, requires performance of visual inspections as described in this practice.  
5.1.2 Operations and maintenance (O&M) activities, such as removal, encapsulation, or enclosure of asbestos-containing materials incidental to repair or replacement of a component, clean-up of debris from a fiber release episode, or other preventive measures, require the performance of visual inspections as described in this practice. See Managing Asbestos in Place7 and Guidance Manual.  
5.1.3 This practice applies to response actions performed under a contract from the building owner, as well as to work performed by the building owner's staff.  
5.2 The specific objectives of the visual inspection process before, during, and at the conclusion of an asbestos abatement project are: to review the extent of asbestos-containing material (ACM) within the scope of work, to monitor performance of the work, and to verify if visible residue, dust or debris, or unremoved material are absent at the completion of removal and clean-up activities.  
5.2.1 The visual inspection process is used to evaluate all four aspects of an asbestos abatement project as follows:
5.2.1.1 Extent of ACM within Scope of Work—The building survey which is intended to locate and quantify asbestos-containing materials is not properly called a “visual inspection” within the context of this practice. To define the extent of ACM involved, a building survey is a necessary prelude to the first step of the visual inspection process. The building survey, which ma...
SCOPE
1.1 This practice covers procedures for performing visual inspections of asbestos response actions to:  
1.1.1 Establish the extent of the required work before it begins;  
1.1.2 Determine the progress and quality of the work and evaluate the completeness of the response action; and  
1.1.3 Evaluate the cleanliness of the work area prior to final air testing for clearance (if performed), and subsequent to dismantling of critical barriers.  
1.2 This practice can be used on an abatement project, or for operations and maintenance (O&M) work, performed by the building owner's staff. It can also be used in conjunction with contract documents between the building owner and other parties involved in an abatement project.
Note 1: Standard contract documents (such as AIA and EJCDC documents) define contractual relationships and responsibilities for projects within the construction industry. Asbestos abatement projects differ from traditional construction projects in the manner of their design and execution, as well as in the type and level of oversight required to substantiate their successful completion. Non-traditional responsibilities are given to the building owner, project designer, and abatement contractor by this practice. Furthermore, responsibilities related to project oversight, inspections, and approvals are placed upon an additional non-traditional representative of the building owner; the project monitor, as defined by this practice. All parties are cautioned that the subject authorities and corresponding responsibilities be understood, mutually agreed upon, and correspondingly addressed with appropriate modifications, if necessary, to the contract documents for a specific project.

1.3.1 The objectives of the visual inspection process;  
1.3.2 The responsibilities and qualifications of the individuals involved in the visual inspections;

SIGNIFICANCE AND USE
5.1 This analysis method is used for the testing of soil samples for asbestos. The emphasis is on detection and analysis of sieved particles for asbestos in the soil. Debris identifiable as bulk building material that is readily separable from the soil is to be analyzed and reported separately.  
5.2 The coarse fraction of the sample (>2 mm to  
5.3 This test method does not describe procedures or techniques required to evaluate the safety or habitability of buildings or outdoor areas potentially contaminated with asbestos-containing materials or compliance with federal, state, or local regulations or statutes. It is the investigator's responsibility to make these determinations.  
5.4 Whereas this test method produces results that may be used for evaluation of sites contaminated by construction, mine, and manufacturing wastes; deposits of natural occurrences of asbestos; and other sources of interest to the investigator, the application of the results to such evaluations and the conclusions drawn there from, including any assessment of risk or liability, is beyond the scope of this test method and is the responsibility of the investigator.
SCOPE
1.1 This test method covers a procedure to: (1) identify asbestos in soil, (2) provide an estimate of the concentration of asbestos in the sampled soil (dried), and (3) optionally to provide a concentration of asbestos reported as the number of asbestos structures per gram of sample.  
1.2 In this test method, results are produced that may be used for evaluation of sites contaminated by construction, mine and manufacturing wastes, deposits of natural occurrences of asbestos (NOA), and other sources of interest to the investigator.  
1.3 This test method describes the gravimetric, sieve, and other laboratory procedures for preparing the soil for analysis as well as the identification and quantification of any asbestos detected. Pieces of collected soil and material embedded therein that pass through a 19-mm sieve will become part of the sample that is analyzed and for which results are reported.  
1.3.1 Asbestos is identified and quantified by polarized light microscopy (PLM) techniques including analysis of morphology and optical properties. Optional transmission electron microscopy (TEM) identification and quantification of asbestos is based on morphology, selected area electron diffraction (SAED), and energy dispersive X-ray analysis (EDXA). Some information about fiber size may also be determined. The PLM and TEM methods use different definitions and size criteria for fibers and structures. Separate data sets may be produced.  
1.4 This test method has an analytical sensitivity of 0.25 % by weight with optional procedures to allow for an analytical sensitivity of 0.1 % by weight.  
1.5 This test method does not purport to address sampling strategies or variables associated with soil environments. Such considerations are the responsibility of the investigator collecting and submitting the sample. Appendix X2 covering elements of soil sampling and good field practices is attached.  
1.6 Units—The values stated in SI units are to be regarded as the standard. Other units may be cited in the method for informational purposes only.  
1.7 Hazards—Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in disease of the lungs including asbestosis, lung cancer, and mesothelioma. Precautions should be taken to avoid creating and breathing airborne asbestos particles when sampling and analyzing materials suspected of containing asbestos.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally ...

SIGNIFICANCE AND USE
5.1 Users of this practice must determine for themselves whether the practices described meet the requirements of local or national authorities regulating asbestos or other fibrous hazards.  
5.2 Variations of this practice have been described by the Asbestos Research Council in Great Britain (8), the Asbestos International Association (AIA) RTM 1 (9), NIOSH 7400, OSHA ID 160, and ISO 8672. Where the counting rules of the latter three methods differ, this is noted in the text.  
5.3 Advantages:  
5.3.1 The technique is specific for fibers. PCM is a fiber counting technique that excludes non-fibrous particles from the analysis.  
5.3.2 The technique is inexpensive, but requires specialized knowledge to carry out the analysis for total fiber counts, at least in so far as the analyst is often required under regulations to have taken a specific training course (for example, NIOSH 582, or equivalent).  
5.3.3 The analysis is quick and can be performed on-site for rapid determination of the concentrations of airborne fibers.  
5.4 Limitations:  
5.4.1 The main limitation of PCM is that fibers are not identified. All fibers within the specified dimensional range are counted. Differential fiber counting may sometimes be used to discriminate between asbestos fibers and fibers of obviously different morphology, such as cellulose and glass fiber. In most situations, differential fiber counting cannot be used to adequately differentiate asbestos from non-asbestos fibers for purposes of compliance with regulations without additional positive identification. If positive identification of asbestos is required, this must be performed by polarized light or electron microscopy techniques, using a different portion of the filter.  
5.4.2 A further limitation is that the smallest fibers visible by PCM are about 0.2 μm in diameter, while the finest asbestos fibers may be as small as 0.02 μm in diameter.  
5.4.3 Where calculation of fiber concentration provides a result exceed...
SCOPE
1.1 This practice2 describes the determination of the concentration of fibers, expressed as the number of such fibers per millilitre of air, using phase contrast microscopy and optionally transmission electron microscopy to evaluate particulate material collected on a membrane filter in the breathing zone of an individual or by area sampling in a specific location. This practice is based on the core procedures provided in the International Organization for Standardization (ISO) Standard ISO 8672  (1),3 the National Institute for Occupational and Health (NIOSH) Manual of Analytical Methods, NIOSH 7400  (2), and the Occupational Safety and Health Administration (OSHA) ID 160  (3). This practice indicates the important points where these methods differ, and provides information regarding the differences, which will allow the user to select the most appropriate procedure for a particular application. However, selecting portions of procedures from different published methods generally requires a user to report that they have used a modification to a method rather than claim they have used the method as written.  
1.2 The practice is used for routine determination of an index of occupational exposure to airborne fibers in workplaces. Workplaces are considered those places where workers are exposed to airborne fibers including asbestos. Additional information on sampling strategies, sample collection (including calibration) and use of sample results for asbestos abatement projects is provided in a standard Practice for Air Monitoring for Management of Asbestos-Containing Materials (WK 8951) currently being considered by ASTM subcommittee E06.24. A further practice has been approved for the specific purpose of sampling and counting airborne fibers in mines and quarries (Practice D7200), although the practice herein may also be used for this purpose. The current practice may be used as a means of monitoring occupational exposure...

SIGNIFICANCE AND USE
5.1 The inhalation of airborne asbestos fibers has been shown to cause asbestosis, lung cancer, and mesothelioma.  
5.1.1 The U.S. Environmental Protection Agency reports that “Effects on the lung are a major health concern from asbestos, as chronic (long-term) exposure to asbestos in humans via inhalation can result in a lung disease termed asbestosis. Asbestosis is characterized by shortness of breath and cough and may lead to severe impairment of respiratory function. Cancer is also a major concern from asbestos exposure, as inhalation exposure can cause lung cancer and mesothelioma (a rare cancer of the thin membranes lining the abdominal cavity and surrounding internal organs), and possibly gastrointestinal cancers in humans. EPA has classified asbestos as a Group A, known human carcinogen” (1).4  
5.1.2 The World Health Organization states: “Exposure to asbestos occurs through inhalation of fibres primarily from contaminated air in the working environment, as well as from ambient air in the vicinity of point sources, or indoor air in housing and buildings containing friable asbestos materials. The highest levels of exposure occur during repackaging of asbestos containers, mixing with other raw materials and dry cutting of asbestos-containing products with abrasive tools” (2).  
5.1.3 The World Bank states: “Health hazards from breathing asbestos dust include asbestosis, a lung scarring disease, and various forms of cancer (including lung cancer and mesothelioma of the pleura and peritoneum). These diseases usually arise decades after the onset of asbestos exposure. Mesothelioma, a signal tumor for asbestos exposure, occurs among workers’ family members from dust on the workers’ clothes and among neighbors of asbestos air pollution point sources” (3).  
5.2 Extensive litigation has occurred worldwide as a result of the health effects of asbestos over the past century, resulting in considerable economic consequences. The regulatory response to asbestos haza...
SCOPE
1.1 This practice describes work practices for asbestos-cement products when maintenance, renovation, and repair are required. This includes common tasks such as drilling and cutting holes in roofing, siding, pipes, etc. that can result in exposure to asbestos fibers if not done carefully. These work practices are supplemented and facilitated by the regulatory, contractual, training, and supervisory provisions of this practice.  
1.2 Materials covered include those installed in or on buildings and facilities and those used in external infrastructure such as water, wastewater, and electrical distribution systems. Also included is pavement made from asbestos-cement manufacturing waste.  
1.3 The work practices described herein are intended for use only with asbestos-cement products already installed in buildings, facilities, and external infrastructure. They are not intended for use in construction or renovation involving the installation of new asbestos-cement products.  
1.4 The work practices are primarily intended to be used in situations where small amounts of asbestos-cement products must be removed or disturbed in order to perform maintenance, renovation, or repair necessary for operation of the building, facility, or infrastructure.  
1.5 The work practices described herein are also applicable for use where the primary objective is the removal of asbestos-cement products from the building or other location, particularly the use of wet methods and other means of dust and fiber control.

SIGNIFICANCE AND USE
4.1 Work practices, engineering controls, personal protective equipment and other precautions to minimize exposure to airborne asbestos fibers have been extensively documented in regulations, training manuals and other publications. The work described in these publications ranges from large-scale abatement projects to minor disturbances and clean-up. Practices E1368 and E2394 address these issues within the context of their subject matter.  
4.2 This practice applies to specific types of asbestos work where the same task is performed by various persons without substantial deviation from a documented procedure and with material containing the same type and similar content of asbestos fiber. The exposure from such operations can be expected to remain fairly consistent as long as these parameters do not vary substantially and the workers have received the required training to perform the task.  
4.3 Because of the variability in field conditions under which large-scale work such as asbestos abatement is performed, the opportunity to collect sufficient personal air samples under conditions similar enough to establish statistical confidence can be questioned. For this reason, this practice does not address the collection of such samples and their use for determining exposure data to apply on other projects. Users with such requirements are referred to the applicable regulations for guidance.  
4.4 There are many tasks, however, that are of short duration and amenable to testing under controlled conditions for assessing worker exposure. These tasks are performed by equipment installers and other tradesmen in the course of their ordinary duties in what this practice refers to as the current job. The following list of potential tasks where ACMs can be disturbed is by no means inclusive and the feasibility of conducting an Exposure Assessment is the responsibility of the user:  
4.4.1 Drilling holes through asbestos floor tile and sheet vinyl flooring,  
4.4.2 Removing ...
SCOPE
1.1 This practice establishes procedures for assessing the exposure of workers to airborne fibers who perform repetitive tasks of short duration where small quantities of asbestos-containing materials must be disturbed in order to perform maintenance and installation activities.  
1.2 This practice describes the facilities and equipment for performing the tasks under controlled conditions for the express purpose of collecting personal air samples to determine worker exposure. The tasks are performed on actual asbestos-containing materials during Exposure Assessment tests and precautions are taken for personal protection and avoiding contamination of adjacent spaces.  
1.3 This practice describes the air sample collection procedures, the analytical methods for the air samples, and the calculation of worker exposure including the use of statistical confidence limits. This practice differentiates between the test to obtain exposure data and the current job to which the data are applied, and describes the duties of the individuals who conduct these separate activities.  
1.4 The results are applied to the current job as defined herein for determining worker protection such as respiratory protection or for other purposes as determined by the competent person responsible for the current job. The results of the tests shall not be applied to current jobs that are expected to differ substantially from the test conditions in work practices, material properties or other factors that might affect the concentration of airborne asbestos fibers.  
1.5 This practice is not intended to be used for asbestos abatement work for which the objective is the removal of asbestos-containing materials. It is designed to assess exposures for short-term repetitive tasks. Compliance with regulatory requirements as to the purpose of the work and limits on the quantity of asbestos-containing materials disturbed is the responsibility of the user.

SIGNIFICANCE AND USE
5.1 This wipe sampling and indirect analysis test method is used for the general testing of surfaces for asbestos. It is used to assist in the evaluation of surfaces in buildings, such as ceiling tiles, shelving, electrical components, duct work, and so forth. This test method provides an index of the concentration of asbestos structures per unit area sampled as derived from a quantitative measure of the number of asbestos structures detected during analysis.  
5.1.1 This test method does not describe procedures or techniques required for the evaluation of the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes. It is the user's responsibility to make these determinations.  
5.1.2 At present, a single direct relationship between asbestos sampled from a surface and potential human exposure does not exist. Accordingly, the user should consider these data in relationship to other available information (for example, air sampling data) in their evaluation.  
5.2 One or more large asbestos-containing particles dispersed during sample preparation may result in large asbestos surface loading results in the TEM analyses of that sample. It is, therefore, recommended that multiple replicate independent samples be secured in the same area, and that a minimum of three such samples be analyzed by the entire procedure.
SCOPE
1.1 This test method covers a procedure to identify asbestos in samples wiped from surfaces and to provide an estimate of the concentration of asbestos reported as the number of asbestos structures per unit area of sampled surface. The procedure outlined in this test method employs an indirect sample preparation technique. It is intended to disperse aggregated asbestos into fundamental fibrils, fiber bundles, clusters, or matrices. However, as with all indirect sample preparation techniques, the asbestos observed for quantification may not represent the physical form of the asbestos as sampled. More specifically, the procedure described neither creates nor destroys asbestos, but it may alter the physical form of the mineral fiber aggregates.  
1.2 This test method describes the equipment and procedures necessary for wipe sampling of surfaces for levels of asbestos structures. The sample is collected onto a particle-free wipe material (wipe) from the surface of a sampling area that may contain asbestos.  
1.2.1 The collection efficiency of this wipe sampling technique is unknown and will vary among substrates. Properties influencing collection efficiency include surface texture, adhesiveness, and other factors.  
1.2.2 This test method is generally applicable for an estimate of the surface loading of asbestos structures starting from approximately 1000 asbestos structures per square centimetre.  
1.3 Asbestos identification by transmission electron microscopy (TEM) is based on morphology, electron diffraction (ED), and energy dispersive X-ray analysis (EDXA).  
1.4 This test method allows determination of the type(s) of asbestos fibers present.  
1.4.1 This test method cannot always discriminate between individual fibers of the asbestos and nonasbestos analogues of the same amphibole mineral.  
1.4.2 There is no lower limit to the dimensions of asbestos fibers that can be detected. However, in practice, the lower limit to the dimensions of asbestos fibers, that can be detected, is variable and dependent on individual microscopists. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.  
1.5 The values stated in SI units are to be regarded as standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulator...

SIGNIFICANCE AND USE
4.1 The DL concept addresses potential measurement interpretation errors. It is used to control the likelihood of reporting a positive finding of asbestos when the measured asbestos level cannot clearly be differentiated from the background contamination level. Specifically, a measurement is reported as being “below the DL” if the measured level is not statistically different than the background level.  
4.2 The DL, along with other measurement characteristics such as bias and precision, is used when selecting a measurement method for a particular application. The DL should be established either at the method development stage or prior to a specific application of the method. The method developer subsequently would advertise the method as having a certain DL. An analyst planning to collect and analyze samples would, if alternative measurement methods were available, want to select a measurement method with a DL that was appropriate for the intended application.5 The most important use of the DL, therefore, takes place at the planning stage of a study, before samples are collected and analyzed.
SCOPE
1.1 This practice presents the procedure for determining the detection limit (DL)2 for measurements of fibers or structures3 using microscopy methods.  
1.2 This practice applies to samples of air that are analyzed either by phase contrast microscopy (PCM) or transmission electron microscopy (TEM), and samples of dust that are analyzed by TEM.  
1.3 The microscopy methods entail counting asbestos structures and reporting the results as structures per cubic centimeter of air (str/cc) or fibers per cubic centimeter of air (f/cc) for air samples and structures per square centimeter of surface area (str/cm2) for dust samples.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Management of asbestos-containing materials in buildings and facilities requires knowledge of the location, type, quantity, and condition of the material. The more complete and accurate the information available, the more appropriate and cost-effective are the control measures used to reduce possible exposure to airborne asbestos fibers. This is true whether the asbestos-containing materials remain undisturbed and completely intact, are selectively removed for maintenance or prior to renovation, or are removed to the greatest extent feasible before demolishing the building or facility.  
4.2 This practice describes three types of surveys that support different objectives. These are the Baseline Survey, the Project Design Survey, and the Pre-Construction Survey.  
4.2.1 The Baseline Survey is a building-wide or facility-wide inspection that provides a general sense of the overall location, type, quantity, and condition of asbestos-containing materials present. It is thorough in that most accessible functional spaces are inspected and bulk samples taken of suspect materials observed. The baseline survey provides information for long-term management of asbestos-containing materials and prioritization of response actions. The presence of asbestos in suspect materials may be assumed or presumed in some cases without bulk samples being taken or analyzed. However, the baseline survey is unobtrusive in that samples are not taken where doing so would result in objectionable damage to surfaces or where institutional barriers preclude access. In a baseline survey, destructive testing is avoided. Posting of signs and labels required for compliance with OSHA regulations would use the information generated during a Baseline Survey.
Note 1: A Baseline Survey is sometimes called an “AHERA” survey because it provides the type of information used for management of asbestos-containing materials in schools. However, the baseline survey described in this practice requires inspec...
SCOPE
1.1 This practice describes procedures for conducting comprehensive surveys of buildings and facilities for the purpose of locating, identifying, quantifying, and assessing asbestos-containing materials.  
1.2 The results of a Comprehensive Building Asbestos Survey are intended to be used for ongoing management of asbestos-containing materials, including Operations and Maintenance (O&M), removal, and other response actions. This includes response actions associated with renovations. A Comprehensive Building Asbestos Survey is also intended to provide information required for removal of asbestos-containing materials prior to demolition of a building or facility.  
1.3 This practice discusses three types of surveys: Baseline Surveys, Project Design Surveys, and Pre-Construction Surveys.  
1.4 This practice discusses the following activities for each of the above types of surveys:  
1.4.1 Planning the survey to meet defined objectives;  
1.4.2 Obtaining and reviewing information on the building or facility including previous surveys and response actions;  
1.4.3 Conducting the physical activities of inspecting the premises and collecting bulk samples of suspect materials;  
1.4.4 Analyzing the bulk samples for asbestos type and content;  
1.4.5 Assessing the Current Condition and Potential for Disturbance of asbestos-containing materials; and  
1.4.6 Preparing a report that includes a narrative discussion of the findings, tabulations of inspection, sampling and analysis results, graphical depiction of the areas inspected, and the results of the assessment.  
1.5 This practice does not include air sampling or surface (dust) sampling for purposes of evaluating a potential exposure hazard from airborne asbestos fibers. The reader may find assistance with exposure assessment determination by reviewing Practice D7886.  
1.6 Warning—Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in d...

SIGNIFICANCE AND USE
4.1 The purpose of this practice is to provide test methods and performance criteria involving encapsulants for surfacing material on an asbestos abatement project in accordance with Practice E1368, including the application of encapsulants to the surfacing material as an abatement measure and the removal of existing encapsulated surfacing material.  
4.1.1 Abatement projects involving application of encapsulants require coverage, penetration, and cohesion/adhesion tests to determine encapsulation requirements during project design, on test patches, and at conclusion of the project to determine completeness of abatement.  
4.1.2 Removal projects requires penetration tests during project design on test patches to determine thicknesses of encapsulated and un-encapsulated surfacing material.  
4.2 The test methods and performance criteria described in this practice may also be used during a Project Design Survey in accordance with Practice E2356 to provide information for preparing the plans and specifications for applying or removing the encapsulated surfacing material.  
4.3 Asbestos-containing surfacing materials installed in buildings may include fireproofing, acoustical and decorative plaster, and soundproofing. Properties not directly addressed in this practice may be important and appropriate test methods should be considered. See Test Methods E84, E119, and E605, and 1-GP-205M2003.  
4.4 The test methods described in this practice are designed to (1) determine the depth of penetration, or lack thereof, of the encapsulant into the matrix of the surfacing material, (2) determine the coverage of the encapsulant on the surfacing material, and (3) to determine the adhesive and cohesive properties of the encapsulated surfacing material.  
4.5 Compliance with the acceptance criteria in this practice and with referenced specifications does not guarantee that the abatement project will pass the visual inspection for completeness of clean-up in Practice E1368, or t...
SCOPE
1.1 This practice covers encapsulants intended to reduce or eliminate the release of asbestos fibers from a matrix of friable spray- or trowel-applied asbestos-containing surfacing material.  
1.2 This practice includes a series of determinations to be conducted in the field on asbestos abatement projects for which encapsulation is being considered or has been performed.  
1.3 This practice is to be used to determine the appropriateness of encapsulation as an abatement measure in accordance with Practice E1368, as part of a Project Design Survey in accordance with Practice E2356, and to demonstrate completeness of abatement in accordance with Practice E1368. Performance of the encapsulated surfacing material for other purposes is not within the scope of this practice. Use Test Methods E84, E119, and E605 to determine other properties of the material.

SCOPE
1.1 There are multiple purposes for determining the loading of asbestos in dust on surfaces. Each particular purpose may require unique sampling strategies, analytical methods, and procedures for data interpretation. Procedures are provided to facilitate application of available methods for determining asbestos surface loadings and/or asbestos loadings in surface dust for comparison between two environments. At present, this guide addresses one application of the ASTM surface dust methods. It is anticipated that additional areas will be added in the future. It is not intended that the discussion of one application should limit use of the methods in other areas.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 This terminology standard is a collective vocabulary relating to sampling and analysis of asbestos. As a convenience to general interest, it contains most of the standard terms, definitions, and nomenclature under the jurisdiction of Committee D22.  
1.2 Many of the entries in this terminology are copied (with attribution) from the standards of origin referenced in Section 2. The standards of origin are noted in bold type at the right margin of the applicable definition.  
1.3 Certain terms in the common language that comprise multiple concepts are included herein with the definition specific to standards and practices of Committee D22.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 The SCCW may be present in the workplace atmosphere where these materials are manufactured, processed, transported, or used. The test methods discussed in this practice can be used to provide guidance when monitoring airborne concentrations of SCCW in these environments.  
5.2 Because of their visibility limitations, a significant fraction of the very small thin fibers that are present in some samples may not be detected by PCM or SEM. Therefore, TEM is considered to be the reference technique for the analysis of airborne SCCW. The TEM must be used to determine both fiber count and morphology when samples are from previously uncharacterized workplaces or materials.  
5.3 Although TEM is the reference technique, PCM or SEM are considered to be the primary screening methods for the analysis of airborne SCCW.  
5.4 Parallel TEM measurements shall be carried out, at least initially, to provide an index or relative measure of the fraction of total fibers that are seen by PCM or SEM. Only in instances when this percentage has been shown to be at a high and reproducible level may the lower resolution techniques (that is, PCM or SEM) be relied on exclusively.
SCOPE
1.1 This practice is intended to assist individuals in the sampling and analysis of single-crystal ceramic whiskers (SCCW), such as silicon carbide and silicon nitride, in the workplace environment. It describes sampling and analytical techniques used to assess the airborne concentration and size distribution of SCCW, which may occur in and around the workplace where these materials are manufactured, processed, transported, or used.  
1.2 The protocols currently in use for asbestos and other fibrous materials have been used as a guide in developing sampling and analytical procedures for characterizing fibers produced from the manufacture and use of SCCW. The sampling and analysis protocols described here have been written specifically for SCCW, however, they may be appropriate for other man-made mineral fibers (MMMF).

SIGNIFICANCE AND USE
5.1 This analysis method is used for the testing of soil samples for asbestos. The emphasis is on detection and analysis of sieved particles for asbestos in the soil. Debris identifiable as bulk building material that is readily separable from the soil is to be analyzed and reported separately.  
5.2 The coarse fraction of the sample (>2 to  
5.3 This test method does not describe procedures or techniques required to evaluate the safety or habitability of buildings or outdoor areas potentially contaminated with asbestos-containing materials or compliance with federal, state, or local regulations or statutes. It is the investigator's responsibility to make these determinations.  
5.4 Whereas this test method produces results that may be used for evaluation of sites contaminated by construction, mine, and manufacturing wastes; deposits of natural occurrences of asbestos; and other sources of interest to the investigator, the application of the results to such evaluations and the conclusions drawn there from, including any assessment of risk or liability, is beyond the scope of this test method and is the responsibility of the investigator.
SCOPE
1.1 This test method covers a procedure to: (1) identify asbestos in soil, (2) provide an estimate of the concentration of asbestos in the sampled soil (dried), and (3) optionally to provide a concentration of asbestos reported as the number of asbestos structures per gram of sample.  
1.2 In this test method, results are produced that may be used for evaluation of sites contaminated by construction, mine and manufacturing wastes, deposits of natural occurrences of asbestos (NOA), and other sources of interest to the investigator.  
1.3 This test method describes the gravimetric, sieve, and other laboratory procedures for preparing the soil for analysis as well as the identification and quantification of any asbestos detected. Pieces of collected soil and material embedded therein that pass through a 19-mm sieve will become part of the sample that is analyzed and for which results are reported.  
1.3.1 Asbestos is identified and quantified by polarized light microscopy (PLM) techniques including analysis of morphology and optical properties. Optional transmission electron microscopy (TEM) identification and quantification of asbestos is based on morphology, selected area electron diffraction (SAED), and energy dispersive X-ray analysis (EDXA). Some information about fiber size may also be determined. The PLM and TEM methods use different definitions and size criteria for fibers and structures. Separate data sets may be produced.  
1.4 This test method has an analytical sensitivity of 0.25 % by weight with optional procedures to allow for an analytical sensitivity of 0.1 % by weight.  
1.5 This test method does not purport to address sampling strategies or variables associated with soil environments. Such considerations are the responsibility of the investigator collecting and submitting the sample. Appendix X2 covering elements of soil sampling and good field practices is attached.  
1.6 Units—The values stated in SI units are to be regarded as the standard. Other units may be cited in the method for informational purposes only.  
1.7 Hazards—Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in disease of the lungs including asbestosis, lung cancer, and mesothelioma. Precautions should be taken to avoid creating and breathing airborne asbestos particles when sampling and analyzing materials suspected of containing asbestos.

SIGNIFICANCE AND USE
5.1 This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere for asbestos structures. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be identified. Most of the airborne asbestos fibers in ambient atmospheres have diameters below the resolution limit of the light microscope. This test method is based on transmission electron microscopy, which has adequate resolution to allow detection of small thin fibers and is currently the only technique capable of unequivocal identification of the majority of individual fibers of asbestos. Asbestos is often found, not as single fibers, but as very complex, aggregated structures, which may or may not also be aggregated with other particles. The fibers found suspended in an ambient atmosphere can often be identified unequivocally if sufficient measurement effort is expended. However, if each fiber were to be identified in this way, the analysis would become prohibitively expensive. Because of instrumental deficiencies or because of the nature of the particulate matter, some fibers cannot be positively identified as asbestos even though the measurements all indicate that they could be asbestos. Therefore, subjective factors contribute to this measurement, and consequently, a very precise definition of the procedure for identification and enumeration of asbestos fibers is required. The method defined in this test method is designed to provide a description of the nature, numerical concentration, and sizes of asbestos-containing particles found in an air sample. The test method is necessarily complex because the structures observed are frequently very complex. The method of data recording specified in the test method is designed to allow reevaluation of the structure-counting data as new applications for measurements are developed. All of the feasible specimen preparation techn...
SCOPE
1.1 This test method2 is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of asbestos structures in ambient atmospheres and includes measurement of the dimension of structures and of the asbestos fibers found in the structures from which aspect ratios are calculated.  
1.1.1 This test method allows determination of the type(s) of asbestos fibers present.  
1.1.2 This test method cannot always discriminate between individual fibers of the asbestos and non-asbestos analogues of the same amphibole mineral.  
1.2 This test method is suitable for determination of asbestos in both ambient (outdoor) and building atmospheres.  
1.2.1 This test method is defined for polycarbonate capillary-pore filters or cellulose ester (either mixed esters of cellulose or cellulose nitrate) filters through which a known volume of air has been drawn and for blank filters.  
1.3 The upper range of concentrations that can be determined by this test method is 7000 s/mm2. The air concentration represented by this value is a function of the volume of air sampled.  
1.3.1 There is no lower limit to the dimensions of asbestos fibers that can be detected. In practice, microscopists vary in their ability to detect very small asbestos fibers. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.  
1.4 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 10 % coverage of the collection filter by particulate matter.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
4.1 Work practices, engineering controls, personal protective equipment and other precautions to minimize exposure to airborne asbestos fibers have been extensively documented in regulations, training manuals and other publications. The work described in these publications ranges from large-scale abatement projects to minor disturbances and clean-up. Practices E1368 and E2394 address these issues within the context of their subject matter.  
4.2 This practice applies to specific types of asbestos work where the same task is performed by various persons without substantial deviation from a documented procedure and with material containing the same type and similar content of asbestos fiber. The exposure from such operations can be expected to remain fairly consistent as long as these parameters do not vary substantially and the workers have received the required training to perform the task.  
4.3 Because of the variability in field conditions under which large-scale work such as asbestos abatement is performed, the opportunity to collect sufficient personal air samples under conditions similar enough to establish statistical confidence can be questioned. For this reason, this practice does not address the collection of such samples and their use for determining exposure data to apply on other projects. Users with such requirements are referred to the applicable regulations for guidance.  
4.4 There are many tasks, however, that are of short duration and amenable to testing under controlled conditions for assessing worker exposure. These tasks are performed by equipment installers and other tradesmen in the course of their ordinary duties in what this practice refers to as the current job. The following list of potential tasks where ACMs can be disturbed is by no means inclusive and the feasibility of conducting an Exposure Assessment is the responsibility of the user:  
4.4.1 Drilling holes through asbestos floor tile and sheet vinyl flooring,  
4.4.2 Removing ...
SCOPE
1.1 This practice establishes procedures for assessing the exposure of workers to airborne fibers who perform repetitive tasks of short duration where small quantities of asbestos-containing materials must be disturbed in order to perform maintenance and installation activities.  
1.2 This practice describes the facilities and equipment for performing the tasks under controlled conditions for the express purpose of collecting personal air samples to determine worker exposure. The tasks are performed on actual asbestos-containing materials during Exposure Assessment tests and precautions are taken for personal protection and avoiding contamination of adjacent spaces.  
1.3 This practice describes the air sample collection procedures, the analytical methods for the air samples, and the calculation of worker exposure including the use of statistical confidence limits. This practice differentiates between the test to obtain exposure data and the current job to which the data are applied, and describes the duties of the individuals who conduct these separate activities.  
1.4 The results are applied to the current job as defined herein for determining worker protection such as respiratory protection or for other purposes as determined by the competent person responsible for the current job. The results of the tests shall not be applied to current jobs that are expected to differ substantially from the test conditions in work practices, material properties or other factors that might affect the concentration of airborne asbestos fibers.  
1.5 This practice is not intended to be used for asbestos abatement work for which the objective is the removal of asbestos-containing materials. It is designed to assess exposures for short-term repetitive tasks. Compliance with regulatory requirements as to the purpose of the work and limits on the quantity of asbestos-containing materials disturbed is the responsibility of the user.

SIGNIFICANCE AND USE
5.1 This practice applies to response actions for all types of asbestos-containing materials, including surfacing materials, thermal systems insulation, and miscellaneous materials, whether friable or not, regardless of the quantities involved and the reason for conducting the response action.  
5.1.1 Abatement for the purpose of removing asbestos-containing materials or encapsulating or enclosing them, regardless of the engineering controls and work practices used, requires performance of visual inspections as described in this practice.  
5.1.2 Operations and maintenance (O&M) activities, such as removal, encapsulation, or enclosure of asbestos-containing materials incidental to repair or replacement of a component, clean-up of debris from a fiber release episode, or other preventive measures, require the performance of visual inspections as described in this practice. See Managing Asbestos in Place and Guidance Manual.  
5.1.3 This practice applies to response actions performed under a contract from the building owner, as well as to work performed by the building owner's staff.  
5.2 The specific objectives of the visual inspection process before, during, and at the conclusion of an asbestos abatement project are: to review the extent of asbestos-containing material (ACM) within the scope of work, to monitor performance of the work, and to verify if visible residue, dust or debris, or unremoved material are absent at the completion of removal and clean-up activities.  
5.2.1 The visual inspection process is used to evaluate all four aspects of an asbestos abatement project as follows:
5.2.1.1 Extent of ACM within Scope of Work—The building survey which is intended to locate and quantify asbestos-containing materials is not properly called a “visual inspection” within the context of this practice. To define the extent of ACM involved, a building survey is a necessary prelude to the first step of the visual inspection process. The building survey, which may...
SCOPE
1.1 This practice covers procedures for performing visual inspections of asbestos response actions to:  
1.1.1 Establish the extent of the required work before it begins;  
1.1.2 Determine the progress and quality of the work and evaluate the completeness of the response action; and  
1.1.3 Evaluate the cleanliness of the work area prior to final air testing for clearance (if performed), and subsequent to dismantling of critical barriers.  
1.2 This practice can be used on an abatement project, or for operations and maintenance (O&M) work, performed by the building owner's staff. It can also be used in conjunction with contract documents between the building owner and other parties involved in an abatement project.Note 1—Standard contract documents (such as AIA and EJCDC documents) define contractual relationships and responsibilities for projects within the construction industry. Asbestos abatement projects differ from traditional construction projects in the manner of their design and execution, as well as in the type and level of oversight required to substantiate their successful completion. Non-traditional responsibilities are given to the building owner, project designer, and abatement contractor by this practice. Furthermore, responsibilities related to project oversight, inspections, and approvals are placed upon an additional non-traditional representative of the building owner; the project monitor, as defined by this practice. All parties are cautioned that the subject authorities and corresponding responsibilities be understood, mutually agreed upon, and correspondingly addressed with appropriate modifications, if necessary, to the contract documents for a specific project.  
1.3 This practice provides the following information:  
1.3.1 The objectives of the visual inspection process;  
1.3.2 The responsibilities and qualifications of the individuals involved in the visual inspections;  
1.3.3 The sch...

SIGNIFICANCE AND USE
4.1 Management of asbestos-containing materials in buildings and facilities requires knowledge of the location, type, quantity, and condition of the material. The more complete and accurate the information available, the more appropriate and cost-effective are the control measures used to reduce possible exposure to airborne asbestos fibers. This is true whether the asbestos-containing materials remain undisturbed and completely intact, are selectively removed for maintenance or prior to renovation, or are removed to the greatest extent feasible before demolishing the building or facility.  
4.2 This practice describes three types of surveys that support different objectives. These are the Baseline Survey, the Project Design Survey, and the Pre-Construction Survey.  
4.2.1 The Baseline Survey is a building-wide or facility-wide inspection that provides a general sense of the overall location, type, quantity, and condition of asbestos-containing materials present. It is thorough in that most accessible functional spaces are inspected and bulk samples taken of suspect materials observed. The baseline survey provides information for long-term management of asbestos-containing materials and prioritization of response actions. The presence of asbestos in suspect materials may be assumed or presumed in some cases without bulk samples being taken or analyzed. However, the baseline survey is unobtrusive in that samples are not taken where doing so would result in objectionable damage to surfaces or where institutional barriers preclude access. In a baseline survey, destructive testing is avoided. Posting of signs and labels required for compliance with OSHA regulations would use the information generated during a Baseline Survey.Note 1—A Baseline Survey is sometimes called an “AHERA” survey because it provides the type of information used for management of asbestos-containing materials in schools. However, the baseline survey described in this practice requires inspection...
SCOPE
1.1 This practice describes procedures for conducting comprehensive surveys of buildings and facilities for the purpose of locating, identifying, quantifying, and assessing asbestos-containing materials.  
1.2 The results of a Comprehensive Building Asbestos Survey are intended to be used for ongoing management of asbestos-containing materials, including Operations and Maintenance (O&M), removal, and other response actions. This includes response actions associated with renovations. A Comprehensive Building Asbestos Survey is also intended to provide information required for removal of asbestos-containing materials prior to demolition of a building or facility.  
1.3 This practice discusses three types of surveys: Baseline Surveys, Project Design Surveys, and Pre-Construction Surveys.  
1.4 This practice discusses the following activities for each of the above types of surveys:  
1.4.1 Planning the survey to meet defined objectives;  
1.4.2 Obtaining and reviewing information on the building or facility including previous surveys and response actions;  
1.4.3 Conducting the physical activities of inspecting the premises and collecting bulk samples of suspect materials;  
1.4.4 Analyzing the bulk samples for asbestos type and content;  
1.4.5 Assessing the Current Condition and Potential for Disturbance of asbestos-containing materials; and  
1.4.6 Preparing a report that includes a narrative discussion of the findings, tabulations of inspection, sampling and analysis results, graphical depiction of the areas inspected, and the results of the assessment.  
1.5 A Comprehensive Building Asbestos Survey provides sufficient information about the asbestos-containing materials in a building or facility for purposes of a real property transaction. In situations where the amount of information required by a party to the transaction is minimal, a Limited Asbestos Screen (see Practice E2308) may suffice in place of the ...

SCOPE
1.1 There are multiple purposes for determining the loading of asbestos in dust on surfaces. Each particular purpose may require unique sampling strategies, analytical methods, and procedures for data interpretation. Procedures are provided to facilitate application of available methods for determining asbestos surface loadings and/or asbestos loadings in surface dust for comparison between two environments.

SIGNIFICANCE AND USE
The purpose of this practice is to provide test methods and performance criteria involving encapsulants for surfacing material on an asbestos abatement project in accordance with Practice E1368, including the application of encapsulants to the surfacing material as an abatement measure and the removal of existing encapsulated surfacing material.
Abatement projects involving application of encapsulants require coverage, penetration and cohesion/adhesion tests to determine encapsulation requirements during project design, on test patches and at conclusion of the project to determine completeness of abatement.
Removal projects requires penetration tests during project design on test patches to determine thicknesses of encapsulated and un-encapsulated surfacing material.
The test methods and performance criteria described in this practice may also be used during a Project Design Survey in accordance with Practice E2356 to provide information for preparing the plans and specifications for applying or removing the encapsulated surfacing material.
Asbestos-containing surfacing materials installed in buildings may include fireproofing, acoustical and decorative plaster, and soundproofing. Properties not directly addressed in this practice may be important and appropriate test methods should be considered. See Test Methods E84, E119, and E605, and 1-GP-205M2003.
The test methods described in this practice are designed to (1) determine the depth of penetration, or lack thereof, of the encapsulant into the matrix of the surfacing material, (2) determine the coverage of the encapsulant on the surfacing material, and (3) to determine the adhesive and cohesive properties of the encapsulated surfacing material.
Compliance with the acceptance criteria in this practice and with referenced specifications does not guarantee that the abatement project will pass the visual inspection for completeness of clean-up in Practice E1368, or that the project will pass final air samp...
SCOPE
1.1 This practice covers encapsulants intended to reduce or eliminate the release of asbestos fibers from a matrix of friable spray- or trowel-applied asbestos-containing surfacing material.
1.2 This practice includes a series of determinations to be conducted in the field on asbestos abatement projects for which encapsulation is being considered or has been performed.
1.3 This practice is to be used to determine the appropriateness of encapsulation as an abatement measure in accordance with Practice E1368, as part of a Project Design Survey in accordance with Practice E2356, and to demonstrate completeness of abatement in accordance with Practice E1368. Performance of the encapsulated surfacing material for other purposes is not within the scope of this practice. Use Test Methods E84, E119, and E605 to determine other properties of the material.

SIGNIFICANCE AND USE
This practice applies to response actions for all types of asbestos-containing materials, including surfacing materials, thermal systems insulation, and miscellaneous materials, whether friable or not, regardless of the quantities involved and the reason for conducting the response action.  
Abatement for the purpose of removing asbestos-containing materials or encapsulating or enclosing them, regardless of the engineering controls and work practices used, requires performance of visual inspections as described in this practice.
Operations and maintenance (O&M) activities, such as removal, encapsulation, or enclosure of asbestos-containing materials incidental to repair or replacement of a component, clean-up of debris from a fiber release episode, or other preventive measures, require the performance of visual inspections as described in this practice. See Managing Asbestos in Place and Guidance Manual.
This practice applies to response actions performed under a contract from the building owner, as well as to work performed by the building owner's staff.
The specific objectives of the visual inspection process before, during, and at the conclusion of an asbestos abatement project are: to review the extent of asbestos-containing material (ACM) within the scope of work, to monitor performance of the work, and to verify if visible residue, dust or debris, or unremoved material are absent at the completion of removal and clean-up activities.
The visual inspection process is used to evaluate all four aspects of an asbestos abatement project as follows:
Extent of ACM within Scope of Work—The building survey which is intended to locate and quantify asbestos-containing materials is not properly called a “visual inspection” within the context of this practice. To define the extent of ACM involved, a building survey is a necessary prelude to the first step of the visual inspection process. The building survey, which may use other building records, is intended to l...
SCOPE
1.1 This practice covers procedures for performing visual inspections of asbestos response actions to:
1.1.1 Establish the extent of the required work before it begins;
1.1.2 Determine the progress and quality of the work and evaluate the completeness of the response action; and
1.1.3 Evaluate the cleanliness of the work area prior to final air testing for clearance (if performed), and subsequent to dismantling of critical barriers.
1.2 This practice can be used on an abatement project, or for operations and maintenance (O&M) work, performed by the building owner's staff. It can also be used in conjunction with contract documents between the building owner and other parties involved in an abatement project.  
Note 1—Standard contract documents (such as AIA and EJCDC documents) define contractual relationships and responsibilities for projects within the construction industry. Asbestos abatement projects differ from traditional construction projects in the manner of their design and execution, as well as in the type and level of oversight required to substantiate their successful completion. Non-traditional responsibilities are given to the building owner, project designer, and abatement contractor by this practice. Furthermore, responsibilities related to project oversight, inspections, and approvals are placed upon an additional non-traditional representative of the building owner; the project monitor, as defined by this practice. All parties are cautioned that the subject authorities and corresponding responsibilities be understood, mutually agreed upon, and correspondingly addressed with appropriate modifications, if necessary, to the contract documents for a specific project.
1.3 This practice provides the following information:
1.3.1 The objectives of the visual inspection process;
1.3.2 The responsibilities and qualifications of the individuals involved in the visual inspections;
1.3.3 The schedul...

SIGNIFICANCE AND USE
Users of this practice must determine for themselves whether the practices described meet the requirements of local or national authorities regulating asbestos or other fibrous hazards.
Variations of this practice have been described by the Asbestos Research Council in Great Britain (8), the Asbestos International Association (AIA) RTM 1 (9), NIOSH 7400, OSHA (Reference Method ID 160), and ISO 8672. Where the counting rules of the latter three methods differ, this is noted in the text.
Advantages
The technique is specific for fibers. PCM is a fiber counting technique that excludes non-fibrous particles from the analysis.
The technique is inexpensive, but requires specialized knowledge to carry out the analysis for total fiber counts, at least in so far as the analyst is often required under regulations to have taken a specific training course (for example, NIOSH 582, or equivalent).
The analysis is quick and can be performed on-site for rapid determination of the concentrations of airborne fibers.
Limitations
The main limitation of PCM is that fibers are not identified. All fibers within the specified dimensional range are counted. Differential fiber counting may sometimes be used to discriminate between asbestos fibers and fibers of obviously different morphology, such as cellulose and glass fiber. In most situations, differential fiber counting cannot be used to adequately differentiate asbestos from non-asbestos fibers for purposes of compliance with regulations without additional positive identification. If positive identification of asbestos is required, this must be performed by polarized light or electron microscopy techniques, using a different portion of the filter.
A further limitation is that the smallest fibers visible by PCM are about 0.2 μm in diameter, while the finest asbestos fibers may be as small as 0.02 μm in diameter.
Where calculation of fiber concentration provides a result exceeding the regulatory standard, non-complia...
SCOPE
1.1 This practice describes the determination of the concentration of fibers, expressed as the number of such fibers per millilitre of air, using phase contrast microscopy and optionally transmission electron microscopy to evaluate particulate material collected on a membrane filter in the breathing zone of an individual or by area sampling in a specific location. This practice is based on the core procedures provided in the International Organization for Standardization (ISO) Standard ISO 8672 (1) , the National Institute for Occupational and Health (NIOSH) Manual of Analytical Methods, NIOSH 7400 (2), and the Occupational Safety and Health Administration (OSHA) Method ID 160 (3). This practice indicates the important points where these methods differ, and provides information regarding the differences, which will allow the user to select the most appropriate procedure for a particular application. However, selecting portions of procedures from different published methods generally requires a user to report that they have used a modification to a method rather than claim they have used the method as written.
1.2 The practice is used for routine determination of an index of occupational exposure to airborne fibers in workplaces. Workplaces are considered those places where workers are exposed to airborne fibers including asbestos. Additional information on sampling strategies, sample collection (including calibration) and use of sample results for asbestos abatement projects is provided in a standard Practice for Air Monitoring for Management of Asbestos-Containing Materials (WK 8951) currently being considered by ASTM subcommittee E06.24. A further practice has been approved for the specific purpose of sampling and counting airborne fibers in mines and quarries (Practice D7200), although the practice herein may also be used for this purpose. The current practice may be used as a means of monitoring occupational exposu...

SIGNIFICANCE AND USE
The inhalation of airborne asbestos fibers has been shown to cause asbestosis, lung cancer, and mesothelioma.  
5.1.1 The U.S. Environmental Protection Agency reports that “Effects on the lung are a major health concern from asbestos, as chronic (long-term) exposure to asbestos in humans via inhalation can result in a lung disease termed asbestosis. Asbestosis is characterized by shortness of breath and cough and may lead to severe impairment of respiratory function. Cancer is also a major concern from asbestos exposure, as inhalation exposure can cause lung cancer and mesothelioma (a rare cancer of the thin membranes lining the abdominal cavity and surrounding internal organs), and possibly gastrointestinal cancers in humans. EPA has classified asbestos as a Group A, known human carcinogen” (1).  
The World Health Organization states: “Exposure to asbestos occurs through inhalation of fibres primarily from contaminated air in the working environment, as well as from ambient air in the vicinity of point sources, or indoor air in housing and buildings containing friable asbestos materials. The highest levels of exposure occur during repackaging of asbestos containers, mixing with other raw materials and dry cutting of asbestos-containing products with abrasive tools” (2).
The World Bank states: “Health hazards from breathing asbestos dust include asbestosis, a lung scarring disease, and various forms of cancer (including lung cancer and mesothelioma of the pleura and peritoneum). These diseases usually arise decades after the onset of asbestos exposure. Mesothelioma, a signal tumor for asbestos exposure, occurs among workers’ family members from dust on the workers’ clothes and among neighbors of asbestos air pollution point sources” (3).
Extensive litigation has occurred worldwide as a result of the health effects of asbestos over the past century, resulting in considerable economic consequences. The regulatory response to asbestos hazards has resulted in civi...
SCOPE
1.1 This practice describes work practices for asbestos-cement products when maintenance, renovation, and repair are required. This includes common tasks such as drilling and cutting holes in roofing, siding, pipes, etc. that can result in exposure to asbestos fibers if not done carefully. These work practices are supplemented and facilitated by the regulatory, contractual, training, and supervisory provisions of this practice.
1.2 Materials covered include those installed in or on buildings and facilities and those used in external infrastructure such as water, wastewater, and electrical distribution systems. Also included is pavement made from asbestos-cement manufacturing waste.
1.3 The work practices described herein are intended for use only with asbestos-cement products already installed in buildings, facilities, and external infrastructure. They are not intended for use in construction or renovation involving the installation of new asbestos-cement products.  
1.4 The work practices are primarily intended to be used in situations where small amounts of asbestos-cement products must be removed or disturbed in order to perform maintenance, renovation, or repair necessary for operation of the building, facility, or infrastructure.
1.5 The work practices described herein are also applicable for use where the primary objective is the removal of asbestos-cement products from the building or other location, particularly the use of wet methods and other means of dust and fiber control.

SIGNIFICANCE AND USE
The purpose of this practice is to provide criteria for the selection of an encapsulant once the decision to encapsulate an asbestos installation has been made. It is assumed that the users of this practice have already made a decision to encapsulate friable asbestos-containing material and that this decision is appropriate. Test Method  and Practice  shall be consulted for the measurement of airborne fibrous materials in the environmental air space.
Since existing asbestos-containing materials installed in buildings may have been applied for a variety of purposes in addition to fire-resistance, encapsulant properties and performance characteristics not addressed in this practice may be important for preservation of original qualities of the asbestos-containing material and should be considered.
The results of the test methods described in this practice on nonasbestos-containing materials will not necessarily predict encapsulant performance on friable asbestos-containing building materials. These test methods are designed to characterize the behavior of the encapsulants, rather than to give a definitive indication of their performance on any particular friable asbestos-containg materials.
The test methods described in this practice measure characteristics of encapsulants in order to retain essential properties of the building material intended for encapsulation.
SCOPE
1.1 This practice covers encapsulants intended to reduce or eliminate the release of asbestos fibers from a matrix of friable spray- or trowel-applied asbestos-containing materials.
1.2 This practice includes: (1) a series of laboratory tests to show whether an encapsulant is capable of acceptable performance on a specified asbestos-free model matrix, and (2) a series of determinations to be conducted in the field at each location for which encapsulation has been accepted, to show whether a given encapsulant is acceptable on the specific asbestos-containing matrix.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This wipe sampling and indirect analysis test method is used for the general testing of surfaces for asbestos. It is used to assist in the evaluation of surfaces in buildings, such as ceiling tiles, shelving, electrical components, duct work, and so forth. This test method provides an index of the concentration of asbestos structures per unit area sampled as derived from a quantitative measure of the number of asbestos structures detected during analysis.
This test method does not describe procedures or techniques required for the evaluation of the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes. It is the user's responsibility to make these determinations.
At present, a single direct relationship between asbestos sampled from a surface and potential human exposure does not exist. Accordingly, the user should consider these data in relationship to other available information (for example, air sampling data) in their evaluation.
One or more large asbestos-containing particles dispersed during sample preparation may result in large asbestos surface loading results in the TEM analyses of that sample. It is, therefore, recommended that multiple replicate independent samples be secured in the same area, and that a minimum of three such samples be analyzed by the entire procedure.
SCOPE
1.1 This test method covers a procedure to identify asbestos in samples wiped from surfaces and to provide an estimate of the concentration of asbestos reported as the number of asbestos structures per unit area of sampled surface. The procedure outlined in this test method employs an indirect sample preparation technique. It is intended to disperse aggregated asbestos into fundamental fibrils, fiber bundles, clusters, or matrices. However, as with all indirect sample preparation techniques, the asbestos observed for quantification may not represent the physical form of the asbestos as sampled. More specifically, the procedure described neither creates nor destroys asbestos, but it may alter the physical form of the mineral fiber aggregates.
1.2 This test method describes the equipment and procedures necessary for wipe sampling of surfaces for levels of asbestos structures. The sample is collected onto a particle-free wipe material (wipe) from the surface of a sampling area that may contain asbestos.
1.2.1 The collection efficiency of this wipe sampling technique is unknown and will vary among substrates. Properties influencing collection efficiency include surface texture, adhesiveness, and other factors.
1.2.2 This test method is generally applicable for an estimate of the surface loading of asbestos structures starting from approximately 1000 asbestos structures per square centimetre.
1.3 Asbestos identification by transmission electron microscopy (TEM) is based on morphology, electron diffraction (ED), and energy dispersive X-ray analysis (EDXA).
1.4 This test method allows determination of the type(s) of asbestos fibers present.
1.4.1 This test method cannot always discriminate between individual fibers of the asbestos and nonasbestos analogues of the same amphibole mineral.
1.4.2 There is no lower limit to the dimensions of asbestos fibers that can be detected. However, in practice, the lower limit to the dimensions of asbestos fibers, that can be detected, is variable and dependent on individual microscopists. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.
1.5 This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
The DL concept addresses potential measurement interpretation errors. It is used to control the likelihood of reporting a positive finding of asbestos when the measured asbestos level cannot clearly be differentiated from the background contamination level. Specifically, a measurement is reported as being “below the DL” if the measured level is not statistically different than the background level.
The DL, along with other measurement characteristics such as bias and precision, is used when selecting a measurement method for a particular application. The DL should be established either at the method development stage or prior to a specific application of the method. The method developer subsequently would advertise the method as having a certain DL. An analyst planning to collect and analyze samples would, if alternative measurement methods were available, want to select a measurement method with a DL that was appropriate for the intended application. The most important use of the DL, therefore, takes place at the planning stage of a study, before samples are collected and analyzed.
SCOPE
1.1 This practice presents the procedure for determining the detection limit (DL) for measurements of fibers or structures using microscopy methods.
1.2 This practice applies to samples of air that are analyzed either by phase contrast microscopy (PCM) or transmission electron microscopy (TEM), and samples of dust that are analyzed by TEM.
1.3 The microscopy methods entail counting asbestos structures and reporting the results as structures per cubic centimeter of air (str/cc) or fibers per cubic centimeter of air (f/cc) for air samples and structures per square centimeter of surface area (str/cm2) for dust samples.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
Management of asbestos-containing materials in buildings and facilities requires knowledge of the location, type, quantity, and condition of the material. The more complete and accurate the information available, the more appropriate and cost-effective are the control measures used to reduce possible exposure to airborne asbestos fibers. This is true whether the asbestos-containing materials remain undisturbed and completely intact, are selectively removed for maintenance or prior to renovation, or are removed to the greatest extent feasible before demolishing the building or facility.
This practice describes three types of surveys that support different objectives. These are the Baseline Survey, the Project Design Survey, and the Pre-Construction Survey.
The Baseline Survey is a building-wide or facility-wide inspection that provides a general sense of the overall location, type, quantity, and condition of asbestos-containing materials present. It is thorough in that most accessible functional spaces are inspected and bulk samples taken of suspect materials observed. The baseline survey provides information for long-term management of asbestos-containing materials and prioritization of response actions. The presence of asbestos in suspect materials may be assumed or presumed in some cases without bulk samples being taken or analyzed. However, the baseline survey is unobtrusive in that samples are not taken where doing so would result in objectionable damage to surfaces or where institutional barriers preclude access. In a baseline survey, destructive testing is avoided. Posting of signs and labels required for compliance with OSHA regulations would use the information generated during a Baseline Survey.
Note 1—A Baseline Survey is sometimes called an “AHERA” survey because it provides the type of information used for management of asbestos-containing materials in schools. However, the baseline survey described in this practice requires inspection, bulk sampl...
SCOPE
1.1 This practice describes procedures for conducting comprehensive surveys of buildings and facilities for the purpose of locating, identifying, quantifying, and assessing asbestos-containing materials.
1.2 The results of a Comprehensive Building Asbestos Survey are intended to be used for ongoing management of asbestos-containing materials, including Operations and Maintenance (O&M), removal, and other response actions. This includes response actions associated with renovations. A Comprehensive Building Asbestos Survey is also intended to provide information required for removal of asbestos-containing materials prior to demolition of a building or facility.
1.3 This practice discusses three types of surveys: Baseline Surveys, Project Design Surveys, and Pre-Construction Surveys.  
1.4 This practice discusses the following activities for each of the above types of surveys:
1.4.1 Planning the survey to meet defined objectives;
1.4.2 Obtaining and reviewing information on the building or facility including previous surveys and response actions;
1.4.3 Conducting the physical activities of inspecting the premises and collecting bulk samples of suspect materials;
1.4.4 Analyzing the bulk samples for asbestos type and content;
1.4.5 Assessing the Current Condition and Potential for Disturbance of asbestos-containing materials; and
1.4.6 Preparing a report that includes a narrative discussion of the findings, tabulations of inspection, sampling and analysis results, graphical depiction of the areas inspected, and the results of the assessment.
1.5 A Comprehensive Building Asbestos Survey provides sufficient information about the asbestos-containing materials in a building or facility for purposes of a real property transaction. In situations where the amount of information required by a party to the transaction is minimal, a Limited Asbestos Screen (see Practice E2308) may suffice in place of the Comprehensi...

SIGNIFICANCE AND USE
This microvacuum sampling and indirect analysis method is used for the general testing of non-airborne dust samples for asbestos. It is used to assist in the evaluation of dust that may be found on surfaces in buildings such as ceiling tiles, shelving, electrical components, duct work, carpet, etc. This test method provides an index of the surface loading of asbestos structures in the dust per unit area analyzed as derived from a quantitative TEM analysis.
This test method does not describe procedures or techniques required to evaluate the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes. It is the user's responsibility to make these determinations.  
At present, no relationship has been established between asbestos-containing dust as measured by this test method and potential human exposure to airborne asbestos. Accordingly, the users should consider other available information in their interpretation of the data obtained from this test method.
This definition of dust accepts all particles small enough to pass through a 1 mm (No. 18) screen. Thus, a single, large asbestos containing particle(s) (from the large end of the particle size distribution) dispersed during sample preparation may result in anomalously large asbestos surface loading results in the TEM analyses of that sample. It is, therefore, recommended that multiple independent samples are secured from the same area, and that a minimum of three samples be analyzed by the entire procedure.
SCOPE
1.1 This test method covers a procedure to (a) identify asbestos in dust and (b) provide an estimate of the surface loading of asbestos in the sampled dust reported as the number of asbestos structures per unit area of sampled surface.
1.1.1 If an estimate of the asbestos mass is to be determined, the user is referred to Test Method D5756.
1.2 This test method describes the equipment and procedures necessary for sampling, by a microvacuum technique, non-airborne dust for levels of asbestos structures. The non-airborne sample is collected inside a standard filter membrane cassette from the sampling of a surface area for dust which may contain asbestos.
1.2.1 This procedure uses a microvacuuming sampling technique. The collection efficiency of this technique is unknown and will vary among substrates. Properties influencing collection efficiency include surface texture, adhesiveness, electrostatic properties and other factors.
1.3 Asbestos identified by transmission electron microscopy (TEM) is based on morphology, selected area electron diffraction (SAED), and energy dispersive X-ray analysis (EDXA). Some information about structure size is also determined.
1.4 This test method is generally applicable for an estimate of the surface loading of asbestos structures starting from approximately 1000 asbestos structures per square centimetre.
1.4.1 The procedure outlined in this test method employs an indirect sample preparation technique. It is intended to disperse aggregated asbestos into fundamental fibrils, fiber bundles, clusters, or matrices that can be more accurately quantified by transmission electron microscopy. However, as with all indirect sample preparation techniques, the asbestos observed for quantification may not represent the physical form of the asbestos as sampled. More specifically, the procedure described neither creates nor destroys asbestos, but it may alter the physical form of the mineral fibers.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere in which asbestos structures are likely to be present. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be identified. Most of the airborne asbestos fibers in ambient atmospheres have diameters below the resolution limit of the light microscope. This test method is based on transmission electron microscopy, which has adequate resolution to allow detection of small thin fibers and is currently the only technique capable of unequivocal identification of the majority of individual fibers of asbestos. Asbestos is often found, not as single fibers, but as very complex, aggregated structures, which may or may not also be aggregated with other particles. The fibers found suspended in an ambient atmosphere can often be identified unequivocally if sufficient measurement effort is expended. However, if each fiber were to be identified in this way, the analysis would become prohibitively expensive. Because of instrumental deficiencies or because of the nature of the particulate matter, some fibers cannot be positively identified as asbestos even though the measurements all indicate that they could be asbestos. Therefore, subjective factors contribute to this measurement, and consequently, a very precise definition of the procedure for identification and enumeration of asbestos fibers is required. The method defined in this test method is designed to provide a description of the nature, numerical concentration, and sizes of asbestos-containing particles found in an air sample. The test method is necessarily complex because the structures observed are frequently very complex. The method of data recording specified in the test method is designed to allow reevaluation of the structure-counting data as new applications for measurements are developed. All of the feasible ...

1.1 This test method is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of asbestos structures in ambient atmospheres and includes measurement of the dimension of structures and of the asbestos fibers found in the structures from which aspect ratios are calculated.

1.1.2 This test method cannot always discriminate between individual fibers of the asbestos and non-asbestos analogues of the same amphibole mineral.
1.2 This test method is suitable for determination of asbestos in both ambient (outdoor) and building atmospheres.
1.2.1 This test method is defined for polycarbonate capillary-pore filters or cellulose ester (either mixed esters of cellulose or cellulose nitrate) filters through which a known volume of air has been drawn and for blank filters.
1.3 The upper range of concentrations that can be determined by this test method is 7000 s/mm2. The air concentration represented by this value is a function of the volume of air sampled.
1.3.1 There is no lower limit to the dimensions of asbestos fibers that can be detected. In practice, microscopists vary in their ability to detect very small asbestos fibers. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.
1.4 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 10 % coverage of the collection filter by particulate matter.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This guide describes factors to be considered by an investigator designing a sampling program to compare the asbestos dust loadings in two environments and presents statistical methods for making the comparison. Each user is responsible for the design of an investigation and the interpretation of data collected when using dust data.
This guide does not deal with situations where dusts of different compositions or from different surfaces are to be evaluated.
This guide describes methods for interpreting the results of sampling and analysis performed in accordance with Test Methods D 5755, D 5756, and D 6480. It may be appropriate to use the procedures in this Guide with other dust collection and analysis methods, but it is the responsibility of the user to make this determination.
The methods described in this guide are not intended to be used alone. They are intended to be used along with various evaluation methods that may include consideration of building use, activities within the building, air sampling, asbestos surveys (refer to Practice E 2356), evaluation of building history and study of building ventilation systems.
This guide describes methods for comparing environments and does not draw any conclusions relating asbestos surface loadings to the potential safety or habitability of buildings.
This guide does not address risk assessments or the use of dust sampling in risk assessment. Health based risk assessments are beyond the scope of this guide.
Warning—Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in disease of the lungs including asbestosis, lung cancer, and mesothelioma. Precautions should be taken to avoid creating and breathing airborne asbestos particles when sampling and analyzing materials suspected of containing asbestos. Regulatory requirements addressing asbestos are defined by USEPA4 ,5 and OSHA6 .
SCOPE
1.1 There are multiple purposes for determining the loading of asbestos in dust on surfaces. Each particular purpose may require unique sampling strategies, analytical methods, and procedures for data interpretation. Procedures are provided to facilitate application of available methods for determining asbestos surface loadings and/or asbestos loadings in surface dust for comparison between two environments. At present, this guide addresses one application of the ASTM surface dust methods. It is anticipated that additional areas will be added in the future. It is not intended that the discussion of one application should limit use of the methods in other areas.

1.2 This practice applies to samples of air that are analyzed either by phase contrast microscopy (PCM) or transmission electron microscopy (TEM), and samples of dust that are analyzed by TEM.
1.3 The microscopy methods entail counting asbestos structures and reporting the results as structures per cubic centimeter of air (str/cc) or fibers per cubic centimeter of air (f/cc) for air samples and structures per square centimeter of surface area (str/cm2) for dust samples.

SCOPE
1.1 This test method is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of asbestos structures in ambient atmospheres and includes measurement of the dimension of structures and of the asbestos fibers found in the structures from which aspect ratios are calculated.
1.1.1 This test method allows determination of the type(s) of asbestos fibers present.
1.1.2 This test method cannot always discriminate between individual fibers of the asbestos and non-asbestos analogues of the same amphibole mineral.
1.2 This test method is suitable for determination of asbestos in both ambient (outdoor) and building atmospheres.
1.2.1 This test method is defined for polycarbonate capillary-pore filters or cellulose ester (either mixed esters of cellulose or cellulose nitrate) filters through which a known volume of air has been drawn and for blank filters.
1.3 The upper range of concentrations that can be determined by this test method is 7000 s/mm2. The air concentration represented by this value is a function of the volume of air sampled.
1.3.1 There is no lower limit to the dimensions of asbestos fibers that can be detected. In practice, microscopists vary in their ability to detect very small asbestos fibers. Therefore, a minimum length of 0.5 m has been defined as the shortest fiber to be incorporated in the reported results.
1.4 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 10 % coverage of the collection filter by particulate matter.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SCOPE
1.1 This practice covers procedures for performing visual inspections of asbestos response actions to:
1.1.1 Establish the extent of the required work before it begins;
1.1.2 Determine the progress and quality of the work and evaluate the completeness of the response action; and
1.1.3 Evaluate the cleanliness of the work area prior to final air testing for clearance (if performed), and subsequent to dismantling of critical barriers.
1.2 This practice can be used on an abatement project, or for operations and maintenance (OM) work, performed by the building owner's staff. It can also be used in conjunction with contract documents between the building owner and other parties involved in an abatement project. Note 1
Standard contract documents (such as AIA and EJCDC documents) define contractual relationships and responsibilities for projects within the construction industry. Asbestos abatement projects differ from traditional construction projects in the manner of their design and execution, as well as in the type and level of oversight required to substantiate their successful completion. Non-traditional responsibilities are given to the building owner, project designer, and abatement contractor by this practice. Furthermore, responsibilities related to project oversight, inspections, and approvals are placed upon an additional non-traditional representative of the building owner; the project monitor, as defined by this practice. All parties are cautioned that the subject authorities and corresponding responsibilities be understood, mutually agreed upon, and correspondingly addressed with appropriate modifications, if necessary, to the contract documents for a specific project.
1.3 This practice provides the following information:
1.3.1 The objectives of the visual inspection process;
1.3.2 The responsibilities and qualifications of the individuals involved in the visual inspections;
1.3.3 The schedule of visual inspection activities during an abatement project and OM work;
1.3.4 The inspection procedures for the various types of abatement work and OM tasks; and
1.3.5 The criteria for certifying work as complete on the basis of the visual inspections.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 Warning-Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in disease of the lungs including asbestosis, lung cancer, and mesothelioma. Precautions in this standard practice should be taken to avoid creating and breathing airborne asbestos particles from materials known or suspected to contain asbestos. See for regulatory requirements addressing asbestos.

SIGNIFICANCE AND USE
This wipe sampling and indirect analysis test method is used for the general testing of surfaces for asbestos. It is used to assist in the evaluation of surfaces in buildings, such as ceiling tiles, shelving, electrical components, duct work, and so forth. This test method provides an index of the concentration of asbestos structures per unit area sampled as derived from a quantitative measure of the number of asbestos structures detected during analysis.
5.1.1 This test method does not describe procedures or techniques required for the evaluation of the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes. It is the user’responsibility to make these determinations.
5.1.2 At present, a single direct relationship between asbestos sampled from a surface and potential human exposure does not exist. Accordingly, the user should consider these data in relationship to other available information (for example, air sampling data) in their evaluation.
One or more large asbestos-containing particles dispersed during sample preparation may result in large asbestos surface loading results in the TEM analyses of that sample. It is, therefore, recommended that multiple replicate independent samples be secured in the same area, and that a minimum of three such samples be analyzed by the entire procedure.
SCOPE
1.1 This test method covers a procedure to identify asbestos in samples wiped from surfaces and to provide an estimate of the concentration of asbestos reported as the number of asbestos structures per unit area of sampled surface. The procedure outlined in this test method employs an indirect sample preparation technique. It is intended to disperse aggregated asbestos into fundamental fibrils, fiber bundles, clusters, or matrices. However, as with all indirect sample preparation techniques, the asbestos observed for quantification may not represent the physical form of the asbestos as sampled. More specifically, the procedure described neither creates nor destroys asbestos, but it may alter the physical form of the mineral fiber aggregates.
1.2 This test method describes the equipment and procedures necessary for wipe sampling of surfaces for levels of asbestos structures. The sample is collected onto a particle-free wipe material (wipe) from the surface of a sampling area that may contain asbestos.
1.2.1 The collection efficiency of this wipe sampling technique is unknown and will vary among substrates. Properties influencing collection efficiency include surface texture, adhesiveness, and other factors.
1.2.2 This test method is generally applicable for an estimate of the surface loading of asbestos structures starting from approximately 1000 asbestos structures per square centimetre.
1.3 Asbestos identification by transmission electron microscopy (TEM) is based on morphology, electron diffraction (ED), and energy dispersive X-ray analysis (EDXA).
1.4 This test method allows determination of the type(s) of asbestos fibers present.
1.4.1 This test method cannot always discriminate between individual fibers of the asbestos and nonasbestos analogues of the same amphibole mineral.
1.4.2 There is no lower limit to the dimensions of asbestos fibers that can be detected. However, in practice, the lower limit to the dimensions of asbestos fibers, that can be detected, is variable and dependent on individual microscopists. Therefore, a minimum length of 0.5 m has been defined as the shortest fiber to be incorporated in the reported results.
This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Precautions in this standard practice should be taken to avoid creating and breathing airborne asbestos particles from materials known or suspected to contain asbestos. Comply with all applicable regulatory requirements addressing asbestos
1.7 This practice does not address safety hazards associated with working on asbestos-cement products such as falling through roof panels or trench cave-ins. The use of power tools presents possible electrical hazards, particularly in wet environments. These and other safety hazards must be considered and controlled in compliance with the employer's policies and applicable regulations.

SCOPE
1.1 This practice describes procedures for conducting comprehensive surveys of buildings and facilities for the purpose of locating, identifying, quantifying and assessing asbestos-containing materials.
1.2 The results of a Comprehensive Building Asbestos Survey are intended to be used for ongoing management of asbestos-containing materials, including Operations Maintenance, removal and other response actions. This includes response actions associated with renovations. A Comprehensive Building Asbestos Survey is also intended to provide information required for removal of asbestos-containing materials prior to demolition of a building or facility.
1.3 This standard practice discusses two types of surveys: Baseline Surveys and Project Design Surveys.
1.4 This standard practice discusses the following activities for each of the above types of surveys:

1.4.6 Preparing a report that includes a narrative discussion of the findings, tabulations of inspection, sampling and analysis results, graphical depiction of the areas inspected, and the results of the assessment.
1.5 A Comprehensive Building Asbestos Survey provides sufficient information about the asbestos-containing materials in a building or facility for purposes of a real property transaction. In situations where the amount of information required by a party to the transaction is minimal, a Limited Asbestos Screen may suffice in place of the Comprehensive Building Asbestos Survey.

SIGNIFICANCE AND USE
This microvacuum sampling and indirect analysis method is used for the general testing of non-airborne dust samples for asbestos. It is used to assist in the evaluation of dust that may be found on surfaces in buildings such as ceiling tiles, shelving, electrical components, duct work, carpet, etc. This test method provides an index of the surface loading of asbestos structures in the dust per unit area analyzed as derived from a quantitative TEM analysis.
5.1.1 This test method does not describe procedures or techniques required to evaluate the safety or habitability of buildings with asbestos-containing materials, or compliance with federal, state, or local regulations or statutes. It is the user’responsibility to make these determinations.  
5.1.2 At present, no relationship has been established between asbestos-containing dust as measured by this test method and potential human exposure to airborne asbestos. Accordingly, the users should consider other available information in their interpretation of the data obtained from this test method.
This definition of dust accepts all particles small enough to pass through a 1 mm (No. 18) screen. Thus, a single, large asbestos containing particle(s) (from the large end of the particle size distribution) dispersed during sample preparation may result in anomalously large asbestos surface loading results in the TEM analyses of that sample. It is, therefore, recommended that multiple independent samples are secured from the same area, and that a minimum of three samples be analyzed by the entire procedure.

1.2 This test method describes the equipment and procedures necessary for sampling, by a microvacuum technique, non-airborne dust for levels of asbestos structures. The non-airborne sample is collected inside a standard filter membrane cassette from the sampling of a surface area for dust which may contain asbestos.
1.2.1 This procedure uses a microvacuuming sampling technique. The collection efficiency of this technique is unknown and will vary among substrates. Properties influencing collection efficiency include surface texture, adhesiveness, electrostatic properties and other factors.
1.3 Asbestos identified by transmission electron microscopy (TEM) is based on morphology, selected area electron diffraction (SAED), and energy dispersive X-ray analysis (EDXA). Some information about structure size is also determined.
1.4 This test method is generally applicable for an estimate of the surface loading of asbestos structures starting from approximately 1000 asbestos structures per square centimetre.
