本文件规定了进行中性盐雾（NSS）、乙酸盐雾（AAS）和铜加速乙酸盐雾（CASS）试验的仪器、试剂和程序，以评估碳纤维增强塑料（CFRP）和金属材料之间接头和粘结结构的耐电偶腐蚀性，有无电流的永久或临时绝缘。

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.
