This International Standard ISO 9227 specifies the apparatus, the reagents and the procedure to be used in conducting the neutral salt spray (NSS), acetic acid salt spray (AASS) and copper-accelerated acetic acid salt spray (CASS) tests for assessment of the corrosion resistance of metallic materials with or without permanent corrosion protection or temporary corrosion protection. It also describes the method employed to evaluate the corrosivity of the test cabinet environment. It does not specify the dimensions of test specimens, the exposure period to be used for a particular product, or the interpretation of results. Such details are provided in the appropriate product specifications. The salt spray tests are particularly useful for detecting discontinuities such as pores and other defects in certain metallic, organic, anodic oxide and conversion coatings. The neutral salt spray test applies to - metals and their alloys: - metallic coatings (anodic and cathodic); - conversion coatings; - anodic oxide coatings; - organic coatings on metallic materials. The acetic acid salt spray test is especially useful for testing decorative coatings of copper + nickel + chromium or nickel + chromium. The copper-accelerated acetic acid salt spray test is useful for testing decorative coatings of copper + nickel + chromium or nickel + chromium1); it has also been found suitable for testing anodic coatings on aluminum. The salt spray methods are all suitable for checking that the comparative quality of a metallic material with or without corrosion protection is maintained. They should not be used for comparative testing to rank different materials relative to each other with respect to corrosion resistance.
