GB/T 19747-2025 Corrosion of metals and alloys—Determination of bimetallic corrosion in atmospheric exposure corrosion tests
Abstract
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.
