A specialized corrosion testing equipment called a CASS cum salt spray test chamber is made to assess the performance and longevity of materials and protective coatings in extremely corrosive environments. The CASS test chamber, in contrast to conventional salt spray chambers, creates a demanding atmosphere that speeds up the corrosion process by using a solution improved with acetic acid and copper chloride. Because of this, it is perfect for testing high-performance coatings such as electroplated surfaces, chrome plating, and anodized aluminum.
