标准摘要
[中文适用范围]： 本文件规定了基于标准图表的图表评级系统，该系统提供了定义经过腐蚀测试的铝及其合金阳极氧化涂层性能水平的方法。 该评级系统适用于以下原因引起的点腐蚀： ——加速试验， — 暴露于腐蚀环境，以及 — 实际使用试验。 本文件仅考虑由于阳极氧化保护涂层的穿透而导致的点蚀。 笔记 [外文原描述]： This document 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. This document takes into account only pitting corrosion resulting from penetration of the protective anodic oxidation coating.
