How to Download ISO 9227:2022 for Free
ISO 9227:2022 is an international standard that 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[^1^].

These tests are useful for detecting discontinuities, such as pores and other defects, in certain metallic, organic, anodic oxide and conversion coatings. They are also suitable for checking that the quality of a metallic material, with or without
corrosion protection, is maintained[^1^].
