|Significance and Use|
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.
