评估车轮漆与各种化学品的化学相容性的测试方法

[中文适用范围]： 本文件提出了测试和评估铝制车轮和车轮装饰表面光洁度的方法，以确保其与各种类型的轮胎、车轮和洗车清洁材料以及可能与这些汽车部件接触的其他化学品的兼容性。人们认识到，这种方法的每个最终用户可能会寻求针对其业务或情况的独特问题的答案。因此，该过程以通用顺序编写，可以严格遵循、重复或修改，以便为用户提供最佳结果。提供了示例决策树来帮助用户选择最适合其需求的曝光步骤序列（参考图 1、2）。如果目的是评估车轮饰面与任何易燃产品的兼容性，则不应使用此程序，因为这些化学物质需要特殊的实验室安全和处理预防措施。 [外文原描述]： This document proposes methods for the testing and evaluation of aluminum wheel and wheel trim surface finishes for compatibility with various types of tire, wheel and car wash cleaning materials, and other chemicals that might come into contact with these automotive components. It is recognized that each end user of this methodology might seek answers to questions that are unique to his business or situation. Therefore, the procedure is written in a generic sequence that could be strictly followed, repeated, or modified in order to provide the user with the best results. Example decision tree are provided to help the user select a sequence of exposure steps that would best suit his needs, (reference Figures 1 , 2 ).This procedure should not be utilized if the intent is to evaluate the compatibility of wheel finishes to any flammable products, because those chemistries would require special laboratory safety and handling precautions.Cross Reference: ASTMD1193,ASTMD1735,J2633_201503
