[Current]Aluminium and aluminium alloys — Anodic oxidation coatings
Specifies requirements for anodic oxidation coatings on aluminium and its alloys for general applications and for external architectural applications. Appendices give guidance on the choice of aluminium grades and coating thickness grades, on the maintenance, handling and transportation of anodised products and on the application of test methods for anodised coatings.
