本文件规定了在低腐蚀性室内环境中用金属标准试样测定腐蚀速率的方法。对于这种直接评估腐蚀性的方法，可以使用以下金属的标准样品采用不同的敏感方法:铜、银、锌、钢和铅。从测量中获得的值被用作确定室内大气腐蚀性的分类标准。

This document specifies methods for determining corrosion rates with standard specimens of metals in indoor atmospheres with low corrosivity. For this direct method of evaluation corrosivity, different sensitive methods can be applied using standard specimens of the following metals: copper, silver, zinc, steel and lead. The values obtained from the measurements are used as classification criteria for the determination of indoor atmospheric corrosivity.
