What is Salt spray testing
Salt spray testing is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. The salt spray testing standard is a clear and specific regulation for the salt spray test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value, etc. In addition, it also puts forward technical requirements for the performance of the salt spray test chamber. The judgment methods of the salt spray testing results include rating judgment method, weighing judgment method, corrosive substance appearance judgment method, and corrosion data statistical analysis method. Salt spray test products are mainly some metal products, through testing to investigate the corrosion resistance of products.
