With salt spray testing, the corrosion behavior of metallic or non-metallic layers can be determined in an accelerated manner. Either neutral (NSS) or acidic (AASS, containing acetic acid) corrosion-promoting atmospheres are created in a chamber with sprayed 5% sodium chloride solution. The corrosiveness of the spray medium can be enhanced even further by adding copper chloride (CASS) to the salt spray.
