This International Standard 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 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. It has also been found suitable for testing anodic coatings
on aluminum.
The copper-accelerated acetic acid salt spray test is useful for testing decorative coatings of
copper + nickel + chromium, or nickel + chromium. 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 are not intended to be used for comparative testing, to rank
different materials relative to each other with respect to corrosion resistance.
