This standard 21/30421421 DC BS ISO 24338. Laminate floor coverings. Determination of abrasion resistance is classified in these ICS categories:
- 97.150 Non-textile floor coverings
This document specifies two methods (A and B) for measuring abrasion of laminate floor covering elements. The tests described measure the ability of the surface layer to resist abrasive wear-through.
Abrasion according to method A is achieved by rotating a test specimen in contact with a pair of loaded cylindrical wheels covered with specified abrasive paper. The resistance to wear according to method B is evaluated by abrading the face of test pieces with a specified abrasive applied by means of two loaded wheels. The number of revolutions of the test specimen required to cause a defined degree of abrasion is measured by both methods.
The precision of the methods is not known. When inter-laboratory data become available, a precision statement will be added.
