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.1.1 This guide discusses procedures that may be used for evaluating the comparative change in pH of reagent water placed on the surface of a properly prepared concrete slab surface.1.2 This guide is intended to be used in conjunction with the flat surface electrode pH meter manufacturer’s calibration procedures, operation instructions, and interpretive data where available.1.3 This guide is intended to be used in conjunction with the pH paper manufacturer’s instructions, product shelf life, and interpretive data where available.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.

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.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. The surfaces may vary from completely textured areas to portions that are flat but separated by textured areas. This test method covers flooring with these interrupted wear surfaces which are not supported by soft, cushioned layers.1.2 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.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.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.1.6 Although carpet tiles, carpet, wood flooring, coatings, films, and paints are not specifically intended to be included in the category of resilient floor coverings, the procedures included in this practice may be useful for preparing concrete floors to receive such finishes.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. See 4.1.1, 7.1.1, and 7.1.2 for specific warning statements.1.8 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.1.9 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.

4.1 Resilient floor tile is subjected to impacts from objects that may be inadvertently dropped on to surfaces. It is not possible to know all of the factors related to the dropped objects (shape, weight, height of drop) or the condition of the environment in which the tile is located (types of subfloor, degree of adhesion to subfloor, temperature). Therefore, this test method can only provide a relative measure of resistance of resilient floor tile to impact.1.1 This test method measures the resistance to impact of resilient floor tile.1.2 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.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its 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.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.
