油漆和清漆 用弹簧笔进行划痕试验

[中文适用范围]： 本文件规定了一种确定涂层对通常手持式装载触针造成的划痕的抵抗力的方法。可以使用点触针（方法 A）或盘触针（方法 B）进行测试。这两种方法都普遍适用，既可用于现场，也可用于曲面。方法 A 也可以应用于小型测试样本（最小尺寸为 30 毫米 × 50 毫米）。测试可以作为“通过/失败”测试（测试要求 I）或分类测试（测试要求 II）进行。 [外文原描述]： This document specifies a method for determining the resistance of a coating to scratches introduced by a usually hand-held loaded stylus. The test can be carried out using a point stylus (method A) or using a disc stylus (method B). Both methods are generally applicable and can be used in the field as well as on curved surfaces. Method A can also be applied on small test specimens (minimum dimensions 30 mm × 50 mm). The test can be carried out as a "pass/fail" test (test requirement I) or as a classification test (test requirement II).
