标准范围
This International Standard specifies a grid rating system that provides a means of defining levels ofperformance of anodic oxidation coatings on aluminium and its alloys that have been subjected to corrosiontests.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 frompenetration of the protective anodic oxidation coating.NOTE 1 ISO 8993[3] describes a similar rating system based on defined chart scales.NOTE 2 The grid rating system is frequently used for rating the results of short-term corrosion tests for relatively thinanodic oxidation coating, such as those used in the automotive industry.
