25、ean Standard specifies the characteristics of agglomerated cork with a wear layer based on polyvinyl chloride and modifications thereof. To encourage the consumer to make an informed choice, the standard includes a classification system (see EN 685) based on intensity of use, which shows where these
26、 floor coverings should give satisfactory service. It also specifies requirements for marking. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and
27、the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

33、geneous polyvinyl chloride layer. Decorative materials, e.g. decorative cork or wood veneers, can be incorporated under the wear layer. 4 Requirements 4.1 General requirements Floor coverings described in this standard shall conform to the appropriate general requirements specified in table 1, when
34、tested in accordance with the methods given therein. 4.2 Classification requirements 4.2.1 Wear group classification Polyvinyl chloride floor coverings shall be classified in the appropriate wear group specified in table 2, when tested in accordance with prEN 660-1 or prEN 660-2. NOTE. The tests are
35、 intended to determine the wear resistance of wear layers either by thickness loss (prEN 660-1) or volume loss (prEN 660-2). Floor coverings described in this standard have a transparent wear layer, are a priori group T and need not be tested. 4.2.2 Level of use classification Floor coverings descri
36、bed in this standard shall be classified as suitable for different levels of use in accordance with the performance requirements specified in table 3, when tested with the methods given therein. Classification shall conform to the scheme specified in EN 685. Licensed Copy: sheffieldun sheffieldun, n
