This International Standard specifies a grid rating system that provides a means of defining levels of performance of anodic oxidation coatings on aluminium and its alloys that have been subjected to corrosion tests. This rating system is applicable to pitting corrosion resulting from - accelerated tests, - exposure to corrosive environments, and - practical service tests. This International Standard takes into account only pitting corrosion of the basis metal resulting from penetration of the protective anodic oxidation coating.
