Salt spray test is a kind of environmental test which mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials.

Salt spray test standard is to specify the conditions of salt spray test, such as temperature, humidity, concentration of sodium chloride solution and PH value. In addition, the technical requirements for the performance of salt spray test box are put forward. The judgment methods of salt spray test results are: rating judgment method, weighing judgment method, corrosion occurrence judgment method, corrosion data statistical analysis method. The products that need salt spray test are mainly some metal products. The corrosion resistance of the products is investigated by testing.

According to customer application scenarios and product requirements, Yuancun's own rating system aims at salt spray test for product design.
