41、irements Floor coverings described in this standard shall conform to the appropriate general requirements, specified in table 1, when tested in accordance with the methods given therein. 4.2 Classification requirements 4.2.1 Wear group classification Polyvinyl chloride floor coverings are classified
42、 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 intended to determine the wear resistance of wear layers defined either by thickness loss (prEN 660-1) or volume loss (prEN 660-2). Floor coverings described in this stan
43、dard shall be classified in wear group T or P. Floor coverings with a transparent wear layer are a priori group T and need not be tested.
