标准范围

本文件规定了一种测试方法，用于在规定的条件下，通过用装载有规定载荷的划痕笔进行划痕，测定油漆、清漆或相关产品的单涂层或多涂层系统对渗透的抵抗力。触针穿透基材，除了在多涂层系统的情况下，在这种情况下，触针可以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，通过对触控笔施加单个指定负载进行测试，以评估是否符合特定规范；或b）？作为评估测试，通过向触针施加增加的负载来确定涂层渗透的最小负载。笔记？无论是本文件还是ISO？1518-2规定了一种使用弯曲触针的方法，该方法在ISO？12137.这三种方法的选择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. The stylus penetrates 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 out:

a)    either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess conformity with a particular specification; or

b)    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 depends on the particular practical problem.
