To encourage the consumer to make an informed ch
21、oice, 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 range of floor coverings, ofte
22、n to those based on polyvinyl chloride or rubber. Such materials are not included in this standard. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the tex

28、ying oil catalysts, which is converted to a semi-elastic mass by an oxidative curing process. 3.2 linoleum Product produced by calendering a homogeneous mixture of linoleum cement, cork and/or woodflour, pigments and inorganic filler onto a fibrous backing. The product is then converted into its fin
29、al form by an oxidative curing process. NOTE. The only chemical cross-linking bondings in linoleum will be those which are formed during the oxidation process. 4 Identification Linoleum shall be identified by its ability to be disintegrated in 0,5 mol/l potassium hydroxide/methanol solution and by t
30、he determination of cement content and ash residue. The minimum amount of linoleum cement shall be 30 % when tested in accordance with prEN 670. The maximum amount of inorganic filler (ash residue) shall be 50 % when tested in accordance with prEN 670. 5 Requirements 5.1 General requirements All cla
31、sses of plain and decorative linoleum shall comply with the appropriate general requirements specified in table 1, when tested in accordance with the methods given therein. Plain and decorative linoleum complying with the requirements of this standard are suitable for use with castor chairs. 5.2 Cla
32、ssification requirements The classification scheme for resilient floor coverings is described in EN 685. The requirements for plain and decorative linoleum in accordance with this scheme are related to the nominal overall thickness of the linoleum, as shown in table 2. Licensed Copy: sheffieldun she
