Scope
This document specifies and compares the methods for determining the corrosion of metals and clad metals in atmospheric corrosion tests.
Note: In this document, the term "metal" refers to metals and their alloys, and the term "clad metal" refers to metals and their alloys with metallic and non-metallic coatings.
This document is applicable to determining the type and extent of corrosion that occurs when different metals come into contact in a natural atmospheric environment.
