This part of IEC 60068-2 specifies a method of assessing a materials resistance to corrosion under salt mist environment. It is applicable to check that the comparative quality of a metallic material, with or without corrosion protection, is maintained from salt mist. It is particularly useful for detecting discontinuities, such as pores and other defects, in certain metallic, organic, anodic oxide and conversion coatings. This test is useful for evaluating the quality and the uniformity of coatings applied to protect metals against corrosion.
