Abstract

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.

Scope

This Standard specifies requirements for anodic oxidation coatings on aluminium and its alloys for general applications and for external architectural applications.
This Standard is not applicable to—
(a) non-porous anodic oxidation coatings of the barrier-layer type;
(b) coatings produced by chromic acid anodising;
(c) hard anodic oxidation coatings that are used mainly for engineering purposes and that have abrasion and wear resistance as their primary characteristics; and
(d) anodic oxidation coatings intended merely to prepare a substrate for subsequent application of organic coatings or the electrodeposition of metals.
NOTES:
1 The coatings covered by this Standard consist mainly of aluminium oxide and are produced by an electrolytic oxidation process during which the aluminium acts as the anode.
2 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are given in Appendix A.
3 Although not specified, the quality and composition of aluminium or aluminium alloys should be suitable for anodising. (See Appendix B).
4 Information on maintenance of coatings is given in Appendix C.
5 Advice on handling and temporary protection of anodised products during transportation and installation is given in Appendix D.
Details of wrought aluminium and aluminium-alloy product types are given in the following Standards:
(i) Sheet and plate................ AS/NZS 1734.
(ii) Drawn wire, rod, bar and strip . AS/NZS 1865.
(iii) Extruded rod, bar, solid and hollow shapes.............................. AS/NZS 1866.
(iv) Drawn tubes.................... AS/NZS 1867.
