标准范围

ISO 8993:2010规定了基于标准图表的图表评级系统，该系统提供了一种定义经过腐蚀测试的铝及其合金上阳极氧化涂层性能水平的方法。该评级系统适用于由以下原因引起的点蚀加速试验，暴露于腐蚀性环境，以及实际服务测试。ISO 8993:2010仅考虑了由保护性阳极氧化涂层渗透引起的点蚀。

ISO 8993:2010 specifies a chart rating system based on standard charts that provides a means of defining levels of performance of anodic oxidation coatings on aluminium and its alloys that have been subjected to corrosion tests.This rating system is applicable to pitting corrosion resulting from

• accelerated tests,
• exposure to corrosive environments, and
• practical service tests.

ISO 8993:2010 takes into account only pitting corrosion resulting from penetration of the protective anodic oxidation coating.
