Salt spray corrosion test is mainly carried out through salt spray test chamber, so as to assess the ability of products to resist salt spray corrosion What are the characteristics and limitations of salt spray test box for salt spray corrosion test? Although the results of salt spray test are far from the actual situation, but before a better test method is found, salt spray test is still an effective method to check the quality and defects of materials and evaluate the corrosion resistance of electronic equipment The salt spray test only emphasizes the environmental factors of the marine environment or the salt air, not all the natural salt fog environmental conditions, so the brine spray test box has its shortcomings and limitations For example: 1) the influence of a certain marine atmosphere cannot be reproduced; 2) the relationship between salt spray corrosion and other medium corrosion cannot be verified; 3) it can not be directly proved that the sample that can withstand this test can guarantee satisfactory results under all corrosion conditions 4) it is not reliable to compare the service life of different materials and coating states 5) the corrosion caused by salt spray and the corrosion caused by damp heat / mould are different and cannot be replaced each other.
