Salt spray testing involves subjecting painted samples or components to a controlled mist or fog of saltwater solution consisting of a specific concentration of sodium chloride (NaCl) in a testing chamber for a predetermined amount of time, typically ranging from 24 to 96 hours depending on specific testing requirements and industry standards. Samples are continuously monitored and evaluated for signs of damage or corrosion during the salt spray test. The testing chamber provides a controlled environment that replicates real-world corrosive conditions, accelerating the corrosion process to allow manufacturers to assess the durability and performance of their paint coatings in a relatively short period. Automotive paint salt spray testing is also highly beneficial when exploring alternative corrosion protection methods, such as galvanization and advanced coating technologies, allowing manufacturers to make informed decisions about incorporating new technologies into their production processes.
