DIN EN ISO 8993:2010-12

This standard specifies a chart rating system based on standard charts that provides a means of defining levels of performance of anodic oxidation coatings on aluminium and its alloys that have been subjected to corrosion test. The rating system is applicable to pitting corrosion resulting from: - accelerated corrosion tests - exposure to corrosive environments - practical service tests. This standard only takes into account pitting corrosion resulting from penetration of the protective anodic oxidation coating. A comparable standard, ISO 8994, describes a similar rating system based on defined grids. The International/European Standard has been prepared under the leadership of ISO/TC 79/SC 2/WG 16 "Revisions for Systematic reviewed TC 79/SC 2 ISO standards" (secretariat: JISC, Japan) in a parallel procedure with CEN/TC 132/WG 15 "Aluminium anodisation" (secretariat: BSI, United Kingdom). On the national level the responsible Working Committee is NA 066-01-09 AA "Anodisch oxidiertes Aluminium" ("Aluminium anodisation") of FNNE.
