Standard Test Method for Measurement of Smoke Obscuration Using a Conical Radiant Source in a Single Closed Chamber, With the Test Specimen Oriented Horizontally

Standard Test Method for Measurement of Smoke Obscuration Using a Conical Radiant Source in a Single Closed Chamber, With the Test Specimen Oriented Horizontally

SCOPE
1.1 This is a fire-test-response standard.
1.2 This test method provides a means of measuring smoke obscuration resulting from subjecting essentially flat materials, products, or assemblies (including surface finishes), not exceeding 25 mm [1 in.] in thickness, in a horizontal orientation, exposed to specified levels of thermal irradiance, from a conical heater, in the presence of a pilot flame, in a single closed chamber. Optional testing modes exclude the pilot flame.
1.3 The principal fire-test-response characteristic obtained from this test method is the specific optical density of smoke from the specimens tested, which is obtained as a function of time, for a period of 10 min.
1.4 An optional fire-test-response characteristic measurable with this test method is the mass optical density (see ), which is the specific optical density of smoke divided by the mass lost by the specimens during the test.
1.5 The fire-test-response characteristics obtained from this test are specific to the specimen tested, in the form and thickness tested, and are not an inherent property of the material, product, or assembly.
1.6 This test method does not provide information on the fire performance of the test specimens under fire conditions other than those conditions specified in this test method. For limitations of this test method, see 5.5.
1.7 Use the SI system of units in referee decisions; see IEEE/ASTM SI-10. The inch-pound units given in brackets are for information only.
1.8 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
1.9 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. This test method may involve hazardous materials, operations, and equipment. See also 6.2.1.2, Section 7, and 11.7.2.
1.10 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.

Standard Practice for Specimen Preparation and Mounting of Wood Products to Assess Surface Burning Characteristics

SIGNIFICANCE AND USE
5.1 The surface burning characteristics of wood products are often evaluated with Test Method E84 to comply with code requirements. This practice describes specimen preparation and mounting procedures for such materials and systems.  
5.2 If it can be demonstrated that none of the methods described in this practice are applicable to a particular wood product, other mounting methods shall be permitted to be used. This information shall be included in the report.  
5.3 The limitations for this procedure are those associated with Test Method E84.
SCOPE
1.1 This practice describes procedures for specimen preparation and mounting when testing wood products to assess flames spread and smoke development as surface burning characteristics using Test Method E84 or Test Method E2768.  
1.1.1 Test Method E2768 uses the same test equipment as Test Method E84.  
1.2 This practice applies also to laminated products factory-produced with a wood substrate (see 8.6). This practice does not apply to wood veneers or facings intended to be applied on site over a wood substrate, which are covered by Practice E2404.  
1.3 Testing is conducted with Test Method E84 or with Test Method E2768.  
1.4 Testing for the reporting of the moisture content of the test specimen is conducted with Test Methods D4442.  
1.5 This practice does not provide pass/fail criteria that can be used as a regulatory tool.  
1.6 Units—Use the values stated in inch-pound units as the standard, in referee decisions. The values in the SI system of units are given in parentheses, for information only; see IEEE/ASTM SI-10 for further details.  
1.7 This fire standard cannot be used to provide quantitative measures.  
1.8 The text of this standard references notes and footnotes which provide explanatory materials. These notes and footnotes shall not be considered requirements of the standard.  
1.9 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. Fire testing involves hazardous materials and equipment. This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E84, or in Test Method E2768, as appropriate. See also Section 10.  
1.10 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.  
1.11 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.

Standard Test Methods for Fire Tests of Fire-Resistive Barrier Systems for Electrical System Components

SIGNIFICANCE AND USE
4.1 These fire-test-response test methods evaluate, under the specified test conditions, the ability of a fire-resistive barrier system to inhibit thermal transmission to the electrical system component within.  
4.2 In these procedures, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from these test methods to predict changes in the fire test response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in these procedures.  
4.3 These test methods provide a measurement of the transmission of heat to the electrical system components within the barrier system.  
4.4 These test methods provide qualification of a fireresistive barrier system as one element of an electrical system designed to maintain continuous operation of critical functions and processes for a specific fire resistance rating.  
4.4.1 In addition to the temperature data provided by these test methods, numerous other factors, such as referenced in 1.4 shall be considered in specifying such a system.
SCOPE
1.1 These test methods cover fire-test-response.  
1.2 These fire-test-response test methods provide information on the temperatures recorded on the electrical system component within a fire-resistive barrier system during the period of exposure.  
1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.4 Potentially important factors and fire characteristics not addressed by these test methods include, but are not limited to:  
1.4.1 The performance of the fire-resistive barrier system constructed with components other than those tested.  
1.4.2 An evaluation of the functionality of the electrical system within the fire-resistive barrier system.  
1.4.3 An evaluation of the ampacity of the electrical system within the fire-resistive barrier system.  
1.4.4 An evaluation of the smoke, toxic gases, corrosivity, or other products of heating.  
1.4.5 A measurement of the flame spread characteristics over the surface of the fire-resistive barrier system.  
1.4.6 An evaluation of through-penetration sealing methods.
Note 1: Refer to Test Method E814 for testing of firestop systems.  
1.4.7 Combustibility of materials in the fire-resistive barrier system or of the electrical system components.  
1.4.8 The need for supports beyond those normally required.  
1.4.9 Environmental conditions in the area of service.  
1.5 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.  
1.6 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 regulatory limitations prior to use.  
1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.8 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.

Standard Guide for Fire-Resistance Experiments

SIGNIFICANCE AND USE
4.1 The methods and procedures set forth in this guide relate to the conduct and reporting of fire-resistance tests obtained from particular fire-resistance tested specimens tested using conditions different than those addressed by Test Methods E119.  
4.2 Data derived from fire tests conducted and reported under this guide are useful for general fire research and as potential input data for use in fire models.  
4.3 It is necessary that users of this guide have knowledge and understanding of the provisions of Test Methods E119, including those pertaining to conditions of acceptance in order to understand how the alternative test conditions relate to those specified in Test Methods E119.  
4.4 Users of this guide should be aware that tests conducted using exposure conditions different than those specified in Test Methods E119 do not provide or generate fire resistance ratings suitable for determining compliance with code or regulatory requirements.  
4.4.1 In Test Methods E119, standard test specimens are subjected to specific exposure conditions. Substitution of different exposure conditions can change the measured fire-test-response characteristics of a test specimen. Therefore, the data are valid for only the alternative exposure conditions used.
SCOPE
1.1 This guide covers the conduct of fire-resistance tests using conditions different than those addressed in Test Methods E119. This guide also addresses the reporting of data derived from those tests.  
1.2 This guide does not provide or generate fire-resistance ratings suitable for determining compliance with code or regulatory requirements comparable to those resulting from tests conducted in accordance with Test Methods E119.  
1.3 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.  
1.4 This guide is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
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 regulatory limitations prior to use.

Standard Test Method for Fire Testing of Mattresses

SIGNIFICANCE AND USE
5.1 This test method provides a means of measuring a variety of fire-test-response characteristics resulting from burning a test specimen, mattress or mattress with foundation. After ignition using a propane gas burner, the test specimen is permitted to burn freely under well-ventilated conditions. The most important fire-test-response characteristic measured in this test method is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. Annex A3 discusses the assumptions and limitations.  
5.3 This test method also provides measures of other fire-test-response characteristics, including smoke obscuration (as the rate of smoke release, total smoke released, or optical density of smoke), combustion gas release (as concentrations of combustion gases), and mass loss, which are important to making decisions on fire safety.  
5.4 In the majority of fires, the most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: (1) as part of fire hazard assessment calculations and (2) to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are also indicators of the toxicity of the atmosphere, but are less crucial for determining combustion completeness and are optional measures; however, fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (flaming source) is common in both accidental and intentional fires in public occupancies. The test method is thus applicable to mattresses in public occupancies. Such facilities include, but are not limited to, health-care facilities, old age convalescent and board and care homes, and college dormitories and residence halls.  
5.6 One ...
SCOPE
1.1 This is a fire-test-response standard.  
1.2 This test method provides a means of determining the burning behavior of mattresses used in public occupancies by measuring specific fire test responses when the test specimen, a mattress or mattress with foundation, is subjected to a specified flaming ignition source under well ventilated conditions.  
1.3 This is a test method for mattresses or mattresses with foundations.  
1.4 Test data are obtained describing the burning behavior, following application of a specific ignition source, from ignition until all burning has ceased, a period of 1 h has elapsed, or flashover appears inevitable.  
1.5 This test method does not provide information on the fire performance of mattresses under fire conditions other than those specified in this test method. In particular, this test method does not apply to smoldering ignition by cigarettes. See 5.12 for further information.  
1.6 The rate of heat release of burning test specimen is measured by an oxygen consumption method. See 5.12.4 for further information.  
1.7 Other measurements are the production of light-obscuring smoke and the concentrations of certain toxic gas species in the combustion gases. See 5.12.5 for further information.  
1.8 The burning behavior is documented visually by photographic or video recordings.  
1.9 Units—Use the SI system of units in referee decisions; see IEEE/ASTM SI-10. The units given in parentheses are for information only.  
1.10 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.

Standard Test Method for Determination of Time to Burn-Through Using the Intermediate Scale Calorimeter (ICAL) Radiant Panel

SIGNIFICANCE AND USE
5.1 This test method is used primarily to determine the time to burn-through and the time to ignition of materials, products, and assemblies.  
5.2 Representative joints and other characteristics of an assembly shall be included in a specimen when these details are part of normal design.  
5.3 This test method is applicable to end-use products not having an ideally planar external surface. The heat flux shall be adjusted to be that which is desired at the average distance of the surface from the radiant panel.  
5.4 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.  
5.5 Representative materials and thicknesses shall be included in a specimen when these details are part of normal design.  
5.6 This method can also be used for research and development of various material types to be included in larger-scale fire test assemblies (for example, Test Methods E119).  
5.7 Test Limitations:  
5.7.1 The test results have limited validity if: (a) the specimen melts sufficiently to overflow the drip tray, or (b) explosive spalling occurs.  
5.7.2 Report observations of specimens that sag, deform, or delaminate.
SCOPE
1.1 This fire-test-response test method assesses the response of materials, products, and assemblies to controlled levels of heat flux with an external igniter.  
1.2 The fire-test-response characteristics determined by this test method include the ignitability and time to burn-through of materials, products, and assemblies under well ventilated conditions.  
1.3 Heat, smoke, and mass loss rate are not within the scope of this test method, but are addressed by Test Method E1623.  
1.3.1 This test method uses the same burner as that described in Test Method E1623. Two burner types are described (Burner A and Burner B).  
1.4 Specimens are exposed to a constant heat flux up to 50 kW/m2 in a vertical orientation. Hot wires are used to ignite the combustible vapors from the specimen.  
1.5 This test method has been developed for evaluations, design, or research and development of materials, products, or assemblies, or for code compliance. The specimen shall be tested in thicknesses and configurations representative of actual end product or system uses.  
1.6 Limitations of the test method are listed in 5.7.  
1.7 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.9 The values stated in SI units are to be regarded as standard.  
1.10 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. Specific information about hazards is given in Section 7.  
1.11 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.

Standard Test Method for Determination of Low Levels of Heat Release Rate for Materials and Products Using an Oxygen Consumption Calorimeter

SIGNIFICANCE AND USE
5.1 This test method is used primarily to determine the heat evolved in, or contributed to, a fire involving materials or products that emit low levels of heat release. The recommended use for this test method is for materials with a total heat release rate measured of less than 10 MJ over the first 20 min test period, and which do not give peak heat release rates of more than 200 kW/m2 for periods extending more than 10 s. Also included is a determination of the effective heat of combustion, mass loss rate, the time to sustained flaming, and (optionally) smoke production. These properties are determined on small size test specimens that are representative of those in the intended end use.  
5.2 This test method is applicable to various categories of products and is not limited to representing a single fire scenario.  
5.3 This test method is not applicable to end-use products that do not have planar, or nearly planar, external surfaces.
SCOPE
1.1 This fire-test-response standard provides a procedure for measuring the response of materials that emit low levels of heat release when exposed to controlled levels of radiant heating with or without an external igniter.  
1.2 This test method differs from Test Method E1354 in that it prescribes a different specific test specimen size, specimen holder, test specimen orientation, a direct connection between the plenum and the top plate of the cone heater assembly to ensure complete collection of all the combustion gases (Fig. 1), and a lower volumetric flow rate for analyses via oxygen consumption calorimetry. It is intended for use on materials and products that contain only small amounts of combustible ingredients or components, such as test specimens that yield a peak heat release of 2 and total heat release of 2.
Note 1: PMMA is typically used to check the general operation of a Cone Calorimeter. PMMA should not be used with this standard as the heat release rate is too high.  
1.3 The rate of heat release is determined by measurement of the oxygen consumption as determined by the oxygen concentration and the flow rate in the exhaust product stream. The effective heat of combustion is determined from a concomitant measurement of test specimen mass loss rate, in combination with the heat release rate. Smoke development (an optional measurement) is measured by obscuration of light by the combustion product stream.  
1.4 Test specimens shall be exposed to initial test heat fluxes generated by a conical radiant heater. External ignition, when used, shall be by electric spark. The test specimen testing orientation is horizontal, independent of whether the end-use application involves a horizontal or a vertical orientation.  
1.5 Ignitability is determined as a measurement of time from initial exposure to time of sustained flaming.  
1.6 This test method has been developed for use for material and product evaluations, mathematical modeling, design purposes, and development and research. Examples of material test specimens include portions of an end-use product or the various components used in the end-use product.  
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.10 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 applic...

Standard Test Method for Fire Testing of Upholstered Furniture

SIGNIFICANCE AND USE
5.1 This test method provides a means to measure a variety of fire-test-response characteristics resulting from burning a specimen of upholstered furniture. The upholstered furniture specimen is allowed to burn freely under well-ventilated conditions after ignition using a propane gas burner. The most important fire-test-response characteristic measured is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. The assumptions and limitations of oxygen depletion calorimetry are discussed in Annex A4, and in particular in A4.1.2.  
5.3 Other fire-test-response characteristics are measured, namely smoke obscuration and combustion gas release, as they are also important in making decisions on fire safety.  
5.4 The most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are less crucial for determining combustion completeness and are optional measures, but fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (a flaming source) is common in both accidental and intentional fires in public occupancies. This test method is thus applicable to upholstered furniture in public occupancies. Such facilities include, but are not limited to, jails, prisons, nursing care homes, health care facilities, public auditoriums, hotels, and motels.  
5.6 It has been shown that if the gas burner is used at a flow rate of 13 L/min for 80 s (equivalent to 19.3 kW), as is the case in California Technical Bulletin (CA TB) 133, it approximates the ignition propensity of five cru...
SCOPE
1.1 This is a fire-test-response standard.  
1.2 The purpose of this test method is to determine the burning behavior of upholstered furniture used in public occupancies by measuring specific fire-test responses when the specimen of furniture is subjected to a specified flaming ignition source under well-ventilated conditions.  
1.3 Data are obtained describing the burning behavior from a specific ignition source until all burning has ceased, a period of 1 h has elapsed, or flashover appears inevitable.  
1.4 This test method does not provide information on the fire performance of upholstered furniture in fire conditions other than those conditions specified. In particular, this test method does not apply to smoldering ignition by cigarettes. See X1.6 for further information.  
1.5 The rate of heat release of the burning specimen is measured by an oxygen consumption method. See X1.6.4 for further information.  
1.6 The production of light obscuring smoke is measured and the concentrations of certain toxic gas species in the combustion gases are determined. See X1.6.5 for further information.  
1.7 The burning behavior is visually documented by photographic or video recordings, whenever possible.  
1.8 The system of units to be used in referee decisions is the SI system of units, see IEEE/ASTM SI-10 only. The units given in parentheses are for information only.  
1.9 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.  
1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

Standard Test Method for Determining the Heat Release Rate of Upholstered Furniture and Mattress Components or Composites Using a Bench Scale Oxygen Consumption Calorimeter

SIGNIFICANCE AND USE
5.1 This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus.  
5.2 Quantitative heat release measurements provide information that can be used for upholstery and mattress product designs and product development.  
5.3 Heat release measurements provide useful information for product development by yielding a quantitative measure of specific changes in fire performance caused by component and composite modifications. Heat release data from this test method will not be predictive of product behavior if the product does not spread flame over its surface under the fire exposure conditions of interest.  
5.4 Test Limitations—The test data are invalid if either of the following conditions occur: (1) explosive spalling; or (2) the specimen swells sufficiently prior to ignition to touch the spark plug, or the specimen swells up to the plane of the heater base during combustion.
SCOPE
1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter.  
1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heat fluxes. The specimen is oriented horizontally, and a spark ignition source is used.  
1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354.  
1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included.  
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 is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.7 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. For specific precautionary statements, see Section 6.  
1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.9 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.

Standard Practice for Ignition Sources

SIGNIFICANCE AND USE
5.1 A variety of standard test methods, specifications, and regulations have been issued by a number of different standards developing organizations and regulatory authorities that contain ignition sources used to assess fire-test-response characteristics associated with flaming and non-flaming ignition. This practice describes such ignition sources and provides information on the standard method in which they are described.  
5.2 The ignition source to be chosen for any specific use needs to be relevant to the fire hazard associated with the intended application. Neither the scope of the standard containing the ignition source nor any other aspect of the standard has any bearing on the use of the ignition source for another application.  
5.3 This practice is not expected to be a fully comprehensive list of ignition sources. If additional ignition sources are identified they can be added to the practice.  
5.4 This practice does not describe test specimen preparation or detailed testing procedures for the materials or products.  
5.5 This practice does not address limitations associated with the ignition sources described in this practice.  
5.6 This practice does not necessarily address the latest edition of any standard referenced.
SCOPE
1.1 This practice describes a series of ignition sources that have been used and that are potentially applicable to assessing fire-test-response characteristics resulting from the ignition of materials, products, or assemblies.  
1.2 This practice does not identify which of the ignition sources described is applicable to any specific use since that is a function of the associated fire hazard (see also 5.2).  
1.3 This practice is not necessarily comprehensive and it is possible that other applicable ignition sources exist (see also 5.3).  
1.4 This practice describes both flaming and non-flaming ignition sources, since the outcome of a non-flaming ignition can be the eventual flaming ignition of these materials or products (see also 4.2).  
1.5 This practice does not provide pass/fail criteria that can be used as a regulatory tool.  
1.6 This fire standard cannot be used to provide quantitative measures.  
1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.9 This practice contains notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard.  
1.10 The values stated in SI units are to be regarded as standard in referee decisions. No other units of measurement are included in this standard. See IEEE/ASTM SI 10 for further details.  
1.11 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.  
1.12 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.

Standard Practice for Extension of Data From Fire Resistance Tests Conducted in Accordance with ASTM E 119

SIGNIFICANCE AND USE
4.1 The methods and procedures set forth in this practice relate to the extension of the fire resistance ratings obtained from particular fire tested specimens to constructions that have not been tested.  
4.2 Users of this practice must have knowledge and understanding of the provisions of Test Method E119 including those pertaining to conditions of acceptance.  
4.3 In order to apply some of the principles described in this practice, reference to the original fire test report will be necessary.  
4.4 In Test Method E119, the specimens are subjected to specific laboratory fire test exposure conditions. Substitution of different test conditions or changes in the end use conditions have the ability to change the measured fire-test-response characteristics. Therefore, the extensions of data are valid only for the fire test exposure conditions described in Test Method E119,.
SCOPE
1.1 This practice covers the extension of fire resistance ratings obtained from fire tests performed in accordance with Test Method E119 to constructions that have not been tested. Test Method E119 evaluates the duration for which test specimens will contain a fire, retain their standard integrity, or both during a predetermined test exposure.  
1.2 This practice is based on principles involving the extension of test data using simple considerations. The acceptance of these principles and their application is based substantially on an analogous worst case proposition.  
1.3 These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method E119. Test Method E119 is a fire-test-response standard.  
1.4 The types of building constructions which are the subject of this practice are categorized as follows: beams; floor and roof assemblies; columns; and walls and partitions. Floor and roof assemblies include such assemblies with ceiling protective membranes.  
1.5 The extension of test data using numerical calculations based on empirical data or theoretical models is not covered in this practice.  
1.6 This practice does not cover the substitution of one proprietary material for another proprietary material, or materials for which fire test data are not presently available.  
1.7 This practice does not purport to be comprehensive in its treatment of non-proprietary modifications of tested constructions. Engineering evaluation or tests are recommended for assessing modifications not specifically covered in this practice.  
1.8 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.9 This standard is used to determine certain fire-test responses of materials, products, or assemblies to heat and flame under controlled conditions by using results obtained from fire-test-response standards. The results obtained from using this standard do not by themselves constitute measures of fire hazard or fire risk.  
1.10 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.  
1.11 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.
