标准范围

本文件规定了两种测量层压板地板覆盖件磨损的方法（A和B）。所述测试测量表面层抵抗磨料磨损的能力。根据方法A，通过旋转与覆盖有指定砂纸的一对负载圆柱轮接触的试样来实现磨损。根据方法B，通过使用两个加载轮施加的指定磨料研磨试样表面来评估耐磨性。通过两种方法测量引起规定磨损程度所需的试样转数。注意这些方法的精度未知。当实验室间数据可用时，将添加精度声明。

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.NOTE      The precision of the methods is not known. When inter-laboratory data become available, a precision statement will be added.
