Specification for anodic oxidation coatings on wrought aluminium for external architectural applications
This British Standard specifies requirements for clear and coloured anodic oxidation coatings on wrought aluminium for external architectural applications.
Guidance on the information to be supplied by the purchaser to the anodizer is given in Appendix A.
Guidance on properties affecting coating performance is given although reflectance and gloss are not specified (see Appendix B).
- NOTE 1: The coatings consist mainly of aluminium oxide and are produced by an electrolytic oxidation process during which the aluminium acts as the anode.
- NOTE 2: The composition of the aluminium is not specified but that used is assumed to be suitable for anodizing (see Appendix C).
- NOTE 3: Temporary protection and maintenance of anodized aluminium after anodizing may be necessary (see Appendix D and Appendix E).
- NOTE 4: The titles of the publications referred to in this standard are listed on the inside back cover.
Requirements for colour (where appropriate), coating thickness, sealing quality and abrasion resistance for clear and coloured coatings.
Also gives guidance on handling and temporary protection during transportation and installation, maintenance and sampling.
