标准摘要
[中文适用范围]： 本国际标准规定了一种使用弯曲（环形或环状）触针测定油漆、清漆或相关产品的单层涂层，或多涂层体系的最上层涂层的耐划痕性的方法。该测试已发现可用于比较不同涂层的耐划痕性。它特别适用于为显示出显著耐划痕性差异的一系列涂覆面板提供相对等级评定。本国际标准未规定使用尖端触针的方法，ISO 1518-1 和 ISO 1518-2 分别规定了两种尖端触针。三种方法之间的选择将取决于具体的实际问题。 [外文原描述]： ISO 12137:2011 specifies a method for determining, using a curved (loop-shaped or ring-shaped) stylus, the mar resistance of a single coating of a paint, varnish or related product, or the upper layer of a multicoat system. This test has been found to be useful in comparing the mar resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in mar resistance. ISO 12137 does not specify a method using a pointed stylus, two of which are specified in ISO 1528‑1 and ISO 1528‑2, respectively. The choice between the three methods will depend on the particular practical problem.
