This document specifies the apparatus, the reagents and the procedure to be used in conducting the neutral salt spray (NSS), acetic acid salt spray (AASS) and copper-accelerated acetic acid salt spray (CASS) tests for assessment of the galvanic corrosion resistance of joints and bonded structures between carbon fibre reinforced plastics (CFRPs) and metallic materials, with or without permanent or temporary insulation for the galvanic current.
Abstract
Overview
ISO 21746:2019 - "Composites and metal assemblies - Galvanic corrosion tests of carbon fibre reinforced plastics (CFRPs) related bonded or fastened structures in artificial atmospheres - Salt spray tests" - defines standardized salt spray methods to assess galvanic corrosion between CFRP and metallic components. The standard covers test apparatus, reagents and procedures for neutral salt spray (NSS), acetic acid salt spray (AASS) and copper‑accelerated acetic acid salt spray (CASS) to evaluate galvanic corrosion resistance of bonded or fastened CFRP/metal joints, with or without insulation.
Key topics and technical requirements
- Test methods covered: NSS, AASS and CASS tailored to CFRP‑metal assemblies.
- Test solutions: Preparation of a 50 g/L ± 5 g/L sodium chloride solution; requirements for reagent purity (e.g., Cu and Ni
