F06 - Resilient Floor Coverings

SIGNIFICANCE AND USE
4.1 Moisture permeating from concrete substrates can detrimentally affect the performance of resilient floor covering systems. All resilient flooring and adhesive manufacturers have a maximum acceptable level of moisture in which their products can perform satisfactorily. If pre-installation moisture tests indicate that the moisture level is unacceptable for the specified floor covering to be installed, one option is to apply a topical treatment to the concrete substrate surface to mitigate the moisture condition. Experience has shown that certain types of membrane-forming moisture mitigation systems have more desirable properties and successful performance than others. Requirements for membrane-forming moisture mitigation systems to be used, and other related details, are generally included as part of the project plans, or specification details, and may vary from the minimum recommendations set forth in this practice.  
4.2 This practice is intended for use after it has been determined that a floor moisture condition exceeds the resilient floor covering or adhesive manufacturer’s requirements, or both, as tested according to Test Methods F1869, F2170, and F2420.  
4.3 Membrane-forming moisture mitigation systems are not intended for use over gypsum-based substrates or other moisture sensitive substrates.
SCOPE
1.1 This practice covers the properties, application, and performance of a two-component resin based membrane-forming moisture mitigation system to high moisture concrete substrates prior to the installation of resilient flooring.  
1.2 This practice includes recommendations for the preparation of the concrete surface to receive a two-component resin based membrane-forming moisture mitigation system.  
1.3 This practice does not supersede written instructions of the two-component resin based membrane-forming moisture mitigation system manufacturer, the resilient flooring manufacturer, underlayment manufacturer, the adhesive manufacturer, or other components of the finish flooring system, or combinations thereof. Users of this practice shall review manufacturer’s technical data sheets and installation instructions for compatibility of system components.  
1.4 The following membrane-forming or non membrane-forming moisture mitigation systems are not included in the scope of this practice:  
1.4.1 Moisture mitigation systems that chemically react with any constituent of the concrete to form a gel or crystalline substance within the concrete.  
1.4.2 Penetrating, water- or solvent-based compounds that do not form a continuous membrane on the concrete surface.  
1.4.3 Water-based membrane-forming moisture mitigation systems are not included in the scope of this document.

SIGNIFICANCE AND USE
4.1 There is typically a higher concentration of soluble alkali salts in the surface region of a concrete slab due to the initial bleeding process of a freshly placed concrete slab. If after a resilient floor covering material is installed there is sufficient moisture within the slab to place these salts into solution a potentially damaging high pH solution can develop beneath the installed material.  
4.2 Results obtained through the use of this guide indicate the comparative pH of reagent water placed on properly prepared concrete slab surfaces only at the time of the procedure and in the specific locations evaluated.  
4.3 If pre-installation surface pH evaluation is required by the manufacturer of the resilient flooring, adhesive, patching/underlayment products or project specifications, their instructions and limitations should be consulted.

SIGNIFICANCE AND USE
4.1 Use this test method to obtain a quantitative value indicating the rate of moisture vapor emission from the surface of a concrete floor and whether or not that floor is acceptable to receive resilient floor covering. The moisture vapor emission rate only reflects the condition of the concrete floor at the time of the test. All concrete subfloors emit some amount of moisture in vapor form. Concrete moisture emission is a natural process driven by environmental conditions. All floor coverings are susceptible to failure from excessive moisture vapor emissions. The moisture vapor emitted from a concrete slab is measured in pounds. This measurement is the equivalent weight of water evaporating from 1000 ft2 of concrete surface in a 24-h period. The calcium chloride moisture test has been the industry standard for making this determination and is a practical, well-established and accepted test of dynamic moisture. It will produce quantified results directly applicable to flooring manufacturer's specifications. The results obtained reflect the condition of the concrete floor surface at the time of testing and may not indicate future conditions.
SCOPE
1.1 This test method covers the quantitative determination of the rate of moisture vapor emitted from below-grade, on-grade, and above-grade (suspended) bare concrete floors.  
1.2 This test shall not be used to evaluate the rate of moisture vapor emitted by gypsum concrete or floors containing lightweight aggregate.  
1.3 This test shall not be used to evaluate moisture vapor emissions over coatings on concrete or through reactive penetrants or over patching or leveling compounds.  
1.4 This quantity of moisture shall be expressed as the rate of moisture vapor emission, measured in pounds of moisture over a 1000 ft2 area during a 24-h period.  
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.

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.

SIGNIFICANCE AND USE
5.1 Moisture in concrete floor slabs affects the performance of flooring systems such as resilient, wood, and textile floor coverings and coatings. Manufacturers of such systems generally require moisture testing be performed before installation of coverings on floor slabs and screeds. The measurement of sub-surface comparative moisture condition in the upper 1.0 in. (25.4 mm) stratum of a concrete slab with a non-destructive moisture meter is one such method.  
5.2 Excessive moisture in floor slabs after installation can cause floor covering system failures such as delamination, bonding failure, deterioration of finish flooring and coatings, and microbial growth.  
5.3 5.3 Comparative moisture content tests indicate the moisture in the slab, which is usually referenced to the percentage of dry weight. That is:
Results indicate conditions at the time of the test.  
5.4 Methods of meter calibration and factors affecting equilibration are described in Section 8.
SCOPE
1.1 This guide focuses on obtaining the comparative moisture condition within the upper 1.0 in. (25.4 mm) stratum in concrete, gypsum, anhydrite floor slabs and screeds for field tests. Due to the wide variation of material mixtures and additives used in floor slabs and screeds, this methodology may not be appropriate for all applications. See 1.2 through 1.8 and Section 11. Where appropriate or when specified, use further testing as outlined in Test Methods F1869 or F2170 before installing a resilient floor covering.  
1.2 This guide is intended for use to determine if there are moisture-related conditions existing on, or in, the floor slabs that could adversely impact the successful application and performance of resilient flooring products.  
1.3 This guide may be used to aid in the diagnosis of failures of installed resilient flooring.  
1.4 This guide is intended to be used in conjunction with meter manufacturer’s operation instructions and interpretive data where available.  
1.5 Where possible or when results need to be quantified, use this guide to determine where additional testing such as Test Methods F1869 or F2170 as specified to characterize the floor slab and the test area environment for moisture, humidity and temperature conditions.  
1.6 This guide may not be suitable for areas that have surface applied moisture migration systems, curing compounds or coatings that cannot be removed or cleaned off sufficiently to allow the moisture to move upwards through the slab. For a floor slab of 6 in. (150 mm) plus thickness, low porosity slabs, slabs with no vapor retarder installed, and slabs where the above surface environmental conditions can have a greater than normal influence on the moisture reduction gradient of the floor slab or screed, consider Test Method F2170 (below surface in situ rh method) as a more suitable test method under these circumstances.  
1.7 This guide is not intended to provide quantitative results as a basis for acceptance of a floor for installation of moisture sensitive flooring finishes systems. Test Methods F1869 or F2170 provide quantitative information for determining if moisture levels are within specific limits. Results from this guide do not provide vital information when evaluating thick slabs, slabs without effective vapor retarders directly under the slab, lightweight aggregate concrete floors, and slabs with curing compound or sealers on the surface.

SIGNIFICANCE AND USE
4.1 Seams in some sheet resilient flooring are sealed to prevent openings from forming between cut edges and prevent penetrations of dirt, liquids, etc., into the seams.
SCOPE
1.1 This practice covers the instructions and precautions to be observed to ensure satisfactory performance of seams in sheet resilient flooring sealed with liquid seam sealers.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its 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.

SIGNIFICANCE AND USE
5.1 The ability of a substrate surface to readily absorb water is a key indicator in determining how to correctly install many types of flooring adhesives, primers, self-leveling underlayments, and other products. Several flooring industry publications such as CRI’s Carpet Installation Standard, RFCI’s Recommended Installation Practice for Homogenous Sheet Flooring, Fully-Adhered, as well as most flooring, adhesive, primer, and underlayment manufacturers reference substrate surface porosity criteria in their application instructions since this directly impacts the spread rate of directly applied material, the open time, and other critical installation factors.  
5.2 Installing flooring products over low or non-absorptive (sometimes referred to as “non-porous”) substrates such as densely machine-troweled concrete, mature and well-hydrated concrete, existing resilient flooring, polymer terrazzo and others may require adjustments to the surface preparation method or product selection to ensure a successful installation.  
5.3 Use this practice to obtain a qualitative assessment of substrate water absorption (porosity) and whether or not that substrate should be regarded as porous/absorptive or non-porous/non-absorptive as these terms relate to the installation of resilient floor coverings, adhesives, self-leveling underlayments, primers, and other products. This practice will produce results directly applicable to determining appropriate surface preparation requirements in accordance with manufacturer’s specifications, but it is in no way meant to replace published manufacturer’s literature regarding the determination of substrate water absorption (porosity) and the impact such has, if any, on substrate preparation requirements and on the installation of their respective materials.  
5.4 Substrates that evidence immediate absorption, are chalky or dusty, or have varying degrees of absorption may require priming or other additional surface preparation prior to subseq...
SCOPE
1.1 This practice covers the determination of whether or not a substrate surface, in lieu of written instruction from a product manufacturer, is considered porous or non-porous prior to the installation of resilient flooring materials.  
1.2 Although carpet tiles, carpet, wood flooring, coatings, films, paints, self-leveling and trowel-grade underlayments, primers, and other associated products are not specifically intended to be included in the category of resilient floor coverings, the procedures included in this practice may be useful for assessing the substrate water absorption for substrates to receive such materials.

ABSTRACT
This practice covers the procedure for determining the acceptability of concrete floors for the installation of resilient flooring. It also includes suggestions for ensuring that the constructed concrete floor is acceptable for such installations but does not cover tests for adequacy of the concrete floor to perform structural requirements. A permanent, effective moisture vapor retarder, of the specified thickness and permeance, is required under all on- or below-grade concrete floors. Concrete floors for resilient floorings should be permanently dry, clean, smooth, structurally sound, and free of substances that may prevent adhesive bonding. Surface cracks, grooves, depression, control joints or other non-moving joints, and other irregularities should be filled or smoothed with latex patching or a recommended underlayment compound. The surface of the floor should be cleaned by scraping, brushing, vacuuming, or any other method. All concrete slabs should be tested for moisture regardless of age or grade level while all concrete floors should be tested for pH before installing resilient flooring.
SCOPE
1.1 This practice covers the determination of the acceptability of a concrete floor for the installation of resilient flooring.  
1.2 This practice includes suggestions for the construction of a concrete floor to ensure its acceptability for installation of resilient flooring.  
1.3 This practice does not cover the adequacy of the concrete floor to perform its structural requirements.  
1.4 This practice covers the necessary preparation of concrete floors prior to the installation of resilient flooring.  
1.5 This practice does not supersede in any manner the resilient flooring or adhesive manufacturer's written instructions. Consult the individual manufacturer for specific recommendations.

1.7 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
3.1 This test method is a meaningful test for determining the indentation recovery properties of uninstalled resilient floor covering.3  
3.2 This test method is intended solely for the purpose of determining compliance, where applicable, with static load requirements set forth in resilient flooring product specifications under the jurisdiction of ASTM Committee F06 on Resilient Floor Coverings.  
3.3 As testing is conducted on uninstalled flooring, results are not an indicator of the floor covering's installed performance.3
SCOPE
1.1 This test method is intended for use in determining the recovery properties of uninstalled resilient floor covering after long-term indentation test, 24 h under the load specified in the detail specification. The reported value, residual indentation, is the depth of the depression remaining 24 h after removal of the specified load.  
1.2 This test method is intended to evaluate ex-factory floor covering and is not intended to evaluate the performance of installed floor coverings.  
1.3 This test method is not intended for use in evaluating the long-term indentation resistance or recovery properties, or both, of resilient floor coverings at loads above those listed in the Precision and Bias statement as described in Section 10.  
1.3.1 Testing at loads above 250 psi is outside the scope of this test method.  
1.4 Testing with any other indentor plate other than the exact plates listed in Section 4 is outside the scope of this test method.  
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.

1.7 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 Much of the cushioned resilient flooring in use today is in household kitchens. Kitchen flooring is frequently subjected to the hazard of dropped tableware and cutting knives, that can puncture the wear layer of cushioned resilient flooring. Food and soil that become embedded in these punctures often can not be removed by ordinary maintenance, resulting in unsightly marks. Moisture, grease, or oils that penetrate to the cushion layer can be wicked into the foam and cause permanent discoloration. Ultimately, the service life of the material is shortened.
SCOPE
1.1 This test method covers the laboratory procedure for determining the resistance of cushioned resilient floor coverings to punctures from dropped pointed objects such as dinner forks.  
1.2 This test method employs a 35-g cylindrical dart with a flat, small-diameter tip that is dropped onto a specimen of flooring. The dart represents the weight of a typical fork and the tip produces a similar puncture to those which result from dropped forks.  
1.3 Flooring with thick wear layers may not puncture under even the most severe drop. Although data can be obtained by increasing the drop height or the weight of the dart, values of this magnitude have no practical application.  
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 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 precaution statement see 8.2.  
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
3.1 This test method is applicable for wear layers with a minimum thickness of 0.001 in. (0.02 mm) to a maximum thickness of 0.1 in. (2.54 mm), where measurements within 0.0005 in. or 0.01 mm are tolerable.
SCOPE
1.1 This test method covers the determination of the thickness of the wear layer of resilient non-textile floor coverings, in tile or sheet form, with or without felt backing or foam layer, by optical measurement.  
1.2 This test method is applicable for wear layers with a minimum thickness of 0.0004 in. (0.01 mm) to a maximum thickness of 0.1 in. (2.54 mm), where measurements within 0.0001 in. or 0.0025 mm are tolerable.  
1.3 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.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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 This test method is designed to measure the vertical distance between any two levels on the face of the flooring, that is, between any two flat areas, between a flat area and any part of a textured area, or between two textured areas. This vertical distance may be of interest in itself or it may be applied to the questions of: (1) how much of the thickness of the flooring is available before the pattern is destroyed; or (2) how deep the depressed areas must be before valley printing ink is not walked on in normal traffic.
SCOPE
1.1 Two important characteristics involved in the manufacture of resilient flooring relate to the smoothness of the wear surface and the hardness of the layers under the wear surface.

SIGNIFICANCE AND USE
4.1 This practice provides minimum recommendations for the installation of self-leveling underlayments suitable to receive resilient floor coverings. This practice establishes the proper preparation of the subfloor, and installation methods and quality control requirements for self-leveling underlayments. This practice addresses any necessary preparation of the self-leveling underlayment’s surface prior to the installation of floor coverings.  
4.2 Actual requirements for self-leveling underlayments are generally included as part of project plans or specifications and may vary from the recommendations set forth in this practice. Provisions in the project documents at variance with this practice shall take precedence.
SCOPE
1.1 This practice covers the installation of self-leveling underlayments, which may include a priming system, over solid wood, wood structural panel subfloors, over concrete, and over certain solidly bonded existing flooring systems such as epoxy floors, ceramic and natural stone tiles, terrazzo, metal subfloors and foils such as steel, copper and lead, solidly bonded patching and other leveling materials as well as properly prepared non water-soluble adhesive residues as recommended by the underlayment manufacturer. This practice also covers the preparation of the self-leveling underlayment’s surface prior to the installation of resilient flooring.  
1.2 This practice points out the factors that are required to be controlled while installing a self-leveling underlayment to be used as a substrate for resilient flooring.

SIGNIFICANCE AND USE
4.1 When subjected to normal in-use traffic conditions, a flooring material is exposed to abrasion caused by the destructive action of fine hard particles. This situation occurs whenever loose debris, dirt and other particulate matter exists between traffic bodies (that is, shoes and a flooring surface). Under continuing exposure to an “abrasive action,” a flooring material may suffer a thickness loss sufficient to reduce its service life.  
4.2 Abrasion resistance measurements of resilient floor coverings can be complicated since the resistance to abrasion is affected by many factors. These may include the physical properties of the material in the floor covering surface, particularly its hardness and resilience; type and degree of added substances, such as fillers and pigments; surface characteristics of the specimen, such as type, depth, and amount of embossing. It can also be affected by conditions of the test, including the type and characteristics of the abradant and how it acts on the area of the specimen being abraded; pressure between the specimen and leather clad brass wheels; and vacuum suction.  
4.3 This test method is designed to simulate one kind of abrasive action and abradant that a flooring may encounter in the field. However, results should not be used as an absolute index of ultimate life because, as noted, there are too many factors and interactions to consider. Also involved are the many different types of service locations. Therefore, the data from this test method are of value chiefly in the development of materials and should not be used without qualifications as a basis for commercial comparisons.
SCOPE
1.1 This test method2 describes a laboratory procedure for determining the abrasion resistance of resilient flooring using an abrader with a grit feeder.3  
1.2 The equipment used in this test method is a modification of the Taber abraser. The regular abrading wheels are replaced by leather clad brass wheels (rollers). As the specimen holder rotates, a grit-feeding device dispenses aluminum oxide grit onto the specimen before the grit passes under the leather clad brass wheels. As the specimen rotates, the rub-wear action of the wheels and abrasive grit causes abrasion on the test piece. Using the vacuum system incorporated in the apparatus, the used grit and abraded material are removed after passing under both wheels.  
1.3 This test method employs a rotary, rubbing action caused by loose abrasive grit and the two abrading wheels. One wheel rubs the specimen from the center outward and the other from the outside toward the center. The wheels traverse a complete circle and have an abrasive action on the rotating specimen at all angles. This action approaches the twisting action between shoe and floor that occurs when a person turns. The use of loose grit serves the function of an abradant and also aids in the rolling action characteristic of normal walking.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.
