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）。使用旋转刷和合成污垢在实验室环境中模拟基于机器的清洗。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。购买本文件时可获得的所有当前修订均包含在购买本文件中。

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.All current amendments available at time of purchase are included with the purchase of this document.
