标准范围

本文件规定了一种基于标准图表的图表评级系统，该系统提供了一种方法，用于定义经过腐蚀试验的铝及其合金阳极氧化涂层的性能水平。该评级体系适用于由腐蚀引起的点蚀-加速试验，-暴露在腐蚀性环境中，以及-实际服务测试。本文件仅考虑保护阳极氧化涂层穿透产生的点蚀。

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.
