BS EN 686:2011EN 686:2011 (E) 4 1 Scope This European Standard specifies the characteristics of plain and decorated linoleum on a foam backing as a compound floor covering, sup
16、plied in roll form. To encourage the consumer to make an informed choice, this European Standard includes a classification system based on intensity of use, which shows where resilient floor coverings should give satisfactory service (see EN 685). It also includes requirements for marking. The term
17、linoleum is frequently incorrectly applied to a range of floor coverings, often to those based on polyvinyl chloride or rubber. Such materials are not included in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For date
