4.1 Ratings are developed by some subjective or comparative evaluation criteria, or both, of a sample(s) to some reference criteria or when compared to a control sample. These parameters generally include change in gloss, color, surface texture, alterations to pattern and possibly restorability of appearance with normal maintenance procedures, including the use of finishes or buffing. Rating is done by a qualified individual or preferably by a panel of qualified observers under specified lighting conditions in accordance with prescribed procedures.1.1 This test method is intended to provide a numerical rating system for classification of resilient floors during the various stages of their wear life in relation to their condition, as perceived by a knowledgeable user.1.2 This test method is intended to allow comparison between two or more samples or groups of samples for differences in visual appearance.1.3 This method provides recommended viewing conditions and lighting for rating visual differences between samples or groups of samples.1.4 This method can be utilized to evaluate change in visual appearance before and after some specified test condition exposure, for example, in service wear due to foot traffic, or other tests where change in appearance might occur.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 problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental health practices and determine the applicability of regulatory limitations prior to use.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.

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.

5.1 The impact sound rating for a floor assembly is determined both by the basic floor assembly and the floor covering on the upper surface. The same floor covering in combination with different basic floor assemblies will not always give the same impact insulation class (IIC) ratings. This test method is designed to provide data that characterize the floor covering alone when installed over concrete slab floors.5.2 The ΔIIC rating calculated in 13.4 is used to compare the effectiveness of different floor coverings on concrete floors.5.3 The impact insulation class (IIC) calculated for the reference concrete floor with a covering provides an indication of the impact sound insulation that the covering will provide with typical, monolithic concrete floors.5.4 When the normalized impact sound pressure levels below a bare concrete slab are known, the difference spectrum calculated in 13.1 may be used to estimate the impact sound pressure levels and hence the IIC that would result if the covering were installed on the slab.5.5 Warning: Difference spectra measured using this method shall not be used to estimate impact sound pressure levels for floors comprising only one or two lightweight floor layers such as oriented strand board or plywood. Such estimated impact sound pressure levels would be very inaccurate.NOTE 1: The difference spectrum calculated in 13.1 gives unreliable estimates of the reduction in impact sound pressure levels due to the floor covering when it is placed on a joist floor incorporating a concrete topping (about 50 mm thick) poured directly on the plywood subfloor or steel deck. The estimated impact sound pressure levels are too low.35.6 This test method closely follows that described in ISO 10140-1 (Annex H) except that the single number rating used is the impact insulation class (IIC) described in Classification E989. The description of the standard concrete floor also differs.NOTE 2: The requirement in Classification E989 that no deviation above the reference contour may exceed 8 dB means that there is no simple relationship between ISO 10140-1 (Annex H) test ratings and those generated by this method.1.1 This test method describes a method for the laboratory measurement of the effectiveness of floor coverings in reducing impact noise from a standard tapping machine through concrete floors. The test results are not necessarily directly related to the subjective evaluations of the floor coverings.1.2 This test method applies to all floor coverings, whether single or multi-layered, as installed on a standard concrete floor. Multi-layered coverings may be factory-assembled or assembled at the test laboratory.1.3 The test method applies only to laboratory measurements. It does not apply to the measurement of the effectiveness of a floor covering in a field situation.1.4 Laboratory Accreditation—A procedure for accrediting a laboratory for performing this test method is given in Method E492.1.5 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.
