\nCorrosion tests in artificial atmospheres\u2014Salt spray tests<\/p>\n
<\/p>\n
1 Scope<\/p>\n
This document 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. It also describes the method employed to evaluate the corrosivity of the test cabinet environment.<\/p>\n
This document is applicable to assessment of the corrosion resistance of metallic materials and coatings, with or without permanent or temporary corrosion protection.<\/p>\n
This document does not specify the dimensions or types 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.<\/p>\n
This document is useful for detecting discontinuities, such as pores and other defects, in metals and their alloys, as well as metallic, organic, anodic oxide and conversion coatings.<\/p>\n
The neutral salt spray (NSS) test applies to:
\n\u2014\u2014metals and their alloys;
\n\u2014\u2014metallic coatings (anodic and cathodic);
\n\u2014\u2014conversion coatings;
\n\u2014\u2014anodic oxide coatings;
\n\u2014\u2014organic coatings on metallic materials.<\/p>\n
The 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 and organic coatings on aluminium.<\/p>\n
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 and organic coatings on aluminium.<\/p>\n
These methods are all suitable for checking that the quality of a metallic material, with or without corrosion protection, is maintained. They are not intended to be used as a means of ranking different materials relative to each other with respect to corrosion resistance or as means of predicting long-term corrosion resistance of the tested material.<\/p>\n
