standardization bsi 3 december 2003en 649:19961 scopethis european standard specifies the characteristics of homogeneous and heterogeneous floor coverings, based on polyvinyl chloride and modifications thereof, supplied in either tile or roll form.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 floor coverings should give satisfactory service. it also specifies requirements for marking.2 normative referencesthis 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 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. for undated references the latest edition of the
