AbolishedTest Methods for anodic oxidation coatings of aluminium and aluminium alloys - Part 3 : Copper accelerated acetic acid salt spray test（CASS test）
铝及铝合金阳极氧化膜检测方法 第3部分：铜加速乙酸盐雾试验（CASS试验）
Application Summary AI generated
This standard specifies the copper-accelerated acetic acid salt spray (CASS) test method for evaluating the corrosion resistance of anodic oxidation coatings on aluminium and aluminium alloys. It is applied in manufacturing and quality control settings, particularly for automotive, architectural, and consumer electronics components, to simulate severe corrosive environments and assess coating durability. The test is used to verify that anodized surfaces meet specified performance requirements for long-term protection against pitting and degradation.
