GB/T 19747-2025 "Metal and alloy corrosion Bimetallic atmospheric exposure corrosion assessment" stipulates the evaluation method of bimetallic exposure corrosion in the atmospheric environment, including test design, exposure procedures, corrosion degree detection and result evaluation. The standard is applicable to the corrosion performance evaluation of bimetallic materials composed of metals and alloys in the atmospheric environment. It provides a basis for judging the corrosion resistance of bimetallic contact, guiding material selection and engineering application, and is of great significance to ensure the durability of metal structures.
