DIN EN 688:2011-07 EN 688:2011 (E) 4 1 Scope This European Standard specifies the characteristics of corklinoleum, supplied in roll form. To encourage the con
17、sumer to make an informed choice, the 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 linoleum is frequently incorrectly applied to a ra
18、nge of floor coverings, often to those based on polyvinyl chloride or rubber. Such materials are excluded from this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE 2 The only chemical cross-linking bondings in corklinoleum will be those which are formed during the oxidation process. Corklinoleum is a composition containing sufficient granulated cork, to giv
