15、011EN 688:2011 (E) 4 1 Scope This European Standard specifies the characteristics of corklinoleum, supplied in roll form. To encourage the consumer to make an informed choice, the standard includes a classification system based on intensity of use, which shows where resilient floor coverings should
16、give satisfactory service (see EN 685). It also includes requirements for marking. The term linoleum is frequently incorrectly applied to a range of floor coverings, often to those based on polyvinyl chloride or rubber. Such materials are excluded from this standard. 2 Normative references The follo

22、poses of this document, the following terms and definitions apply. 3.1 linoleum cement binder in linoleum, consisting of a mixture of linseed oil and/or other vegetable drying oils, rosin and drying oil catalysts, which is converted to a semi-elastic mass by an oxidative curing process 3.2 corklinol
23、eum product produced by calendering a homogeneous mixture of linoleum cement, granulated cork, pigments and inorganic filler onto a fibrous backing NOTE 1 The product is then converted into its final form by an oxidative curing process. NOTE 2 The only chemical cross-linking bondings in corklinoleum
24、 will be those which are formed during the oxidation process. Corklinoleum is a composition containing sufficient granulated cork, to give underfoot comfort and impact sound reduction. 4 Identification Corklinoleum shall be identified by its ability to be disintegrated in 0,5 mol/l potassium hydroxi
25、de/methanol solution. The maximum amount of inorganic filler (ash residue) shall be 25 % when tested in accordance with EN 670. Corklinoleum shall be distinguished from other types of linoleum by its density. 5 Requirements 5.1 General requirements All classes of corklinoleum shall comply with the g
