BS 687:2019 pdf download – Resilient floor coverings – Specification for plain and decorative linoleum on a corkment backing
This document specifies the characteristics of plain and decorative linoleum on a corkment backing as acompound floor covering, supplied in roll form.
To encourage the consumer to make an informed choice, this standard includes a classification systembased on intensity of use, which shows where resilient floor coverings should give satisfactory service(see EN ISO 10874). It also includes requirements for marking.
The term ‘linoleum’ is frequently incorrectly applied to a range of floor coverings, often to those basedon polyvinyl chloride or rubber.Such materials are not included in this document.

3.1
linoleum with corkment backing
product produced by calendering a homogeneous mixture of linoleum cement, cork and/or woodflour,pigments and inorganic filler onto a corkment backing
Note 1 to entry: The product is then converted into its final form by an oxidative curing process; the only
chemical cross-linking bondings in linoleum will be those which are formed during the oxidation process.
3.2
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
3.3
corkment
backing or underlay produced by calendering a homogeneous mixture of linoleum cement, granulated cork, pigments and inorganic fillers on a fibrous backing
Note 1 to entry: The product is then converted into its final form by an oxidative curing process.
4 Identification
Linoleum shall be identified by its ability to be disintegrated in 0,5 mol/l potassium
hydroxide/methanol solution and by the determination of cement content and ash residue.
The minimum amount of linoleum cement shall be 30 % when tested in accordance with EN ISO 26985.
The maximum amount of inorganic filler (ash residue) shall be 50 % when tested in accordance with EN ISO 26985.
Corkment shall be identified by its ability to be disintegrated in 0,5 mol/l potassium hydroxide/methanol solution.
