涂层划格试验不同标准的对比分析

Comparison and Analysis of Coating cross-cut Test in different Standards

对比介绍了GB/T 9286—1998、ASTM D 3359—2017、ISO 2409—2020这3个关于涂层划格试验标准的主要内容,重点介绍了基本操作及不同标准间的差异。针对划格深度影响试验准确性的问题,以实例进行了说明。

This paper compared the main concepts of three cross-cut testing standards(i.e.,GB/T 9286,ASTM D 3359 and ISO 2409)and particularly described basic operation and the differences of these standards.In addition,an example is used to explain how the cross-cutting depth affects the accuracy of the test result.
