本文件规定了评估有机油漆涂层耐刮擦性的试验程序，尤其是汽车工业中使用的油漆涂层（即评估其耐洗车性）。在实验室环境中，使用旋转刷和合成污垢模拟机器清洗。测试条件设计为尽可能接近洗车场的真实条件。如果选择合适的测试参数，该方法也可用于测试保护性塑料薄膜和塑料组件。

This document specifies a test procedure for assessing the scratch resistance of organic paint coatings, in particular paint coatings used in the automotive industry (i.e. for assessing their car-wash resistance). Machine-based washing is simulated in the laboratory environment using a rotating brush and synthetic dirt. The test conditions have been designed to be as close as possible to the real conditions in a car-wash. If the test parameters are suitably chosen, the method can also be used for testing protective plastics films and plastics components.
