BS 4479-5:1990 pdf free download.Design of articles that are to be coated – Recommendations for anodic oxidation coatings.
This Part of BS 4479 gives recommendations for the design of metal parts that are to be coated by anodizing.
This Palt of BS 4479 also outlines the nature of the processes involved, gives typical applications for finished parts, and also outlines the prime features of an anodized finish.
NOTE 1: It is recommended that Part 1 of BS 4479 be read in conjunction with this Part. Part 1 includes a list of British Standards relating to processes covered by BS 4479 but not necessarily referred to in each Part.
NOTE 2: The titles of the publications referred to in this standard are listed on the inside back cover.

It is essential that the design of any article required to be coated should take into account not only the function of the article and its method of manufacture but also the limitations imposed by the coating.
Anodizing is an electrochemical process, whereby the natural oxide coating present on particular metals may be thickened. The process is applied principally to aluminium and its alloys, but it may also be applicable to materials such as magnesium, niobium, tantalum and titanium.
