The JIS Z2371-2015 standard specifies a specific method for salt spray testing, which is used to test the corrosion resistance of materials and coatings in a salt fog environment. This test method is suitable for various materials, such as metals, Coatings and plastics, to evaluate their corrosion resistance by simulating salt fog conditions in the marine environment. The standard specifies test equipment, test conditions and evaluation methods to ensure the accuracy and conformity of test results, and is widely used in quality control of materials and product certification.
