标准范围

本文件规定了一种试验方法，用于在规定的条件下，通过使用带有规定负载的划痕笔进行划痕，测定涂料、清漆或相关产品的单涂层或多涂层系统的抗渗透性。触针可穿透基材，但多层涂层系统除外，在这种情况下，触针可穿透基材或中间涂层。可以执行指定的方法a） 作为“通过/失败”测试，通过在触针上施加单一规定负载进行测试，以评估是否符合特定规范，或b） 作为一种评估测试，通过向触针施加越来越大的载荷来确定穿透涂层的最小载荷。注:本文件和ISO 1518-2均未规定使用弯曲触针的方法，这在ISO 12137中有规定。这三种方法之间的选择将取决于具体的实际问题。

This document specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a multi-coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat.The method specified can be carried outa) either as a "pass/fail" test, by testing with a single specified load applied to the stylus to assess conformity with a particular specification, orb) as an assessment test by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated.NOTE Neither this document nor ISO 1518？2 specifies a method using a curved stylus, which is specified in ISO 12137. The choice between the three methods will depend on the particular practical problem.
