Four of the most commonly used methods of application, i.e. spraying, dipping, powder coating and electrophoretic coating. Illustrates preferred and deprecated design features.

This Part of BS 4479 gives recommendations for the design of parts that are to be coated by painting or varnishing and covers four of the most commonly used methods whereby such coatings are applied, i.e.:

1. spray coatings;
2. dip coatings;
3. powder coatings;
4. electrophoretic coatings.

This Part of BS 4479 outlines the salient features of each method of application, and highlights the advantages and short-comings of each.

Design considerations are clearly given for each of the four processes, and Annex A illustrates some preferred and deprecated design features.

NOTE 1 Reference is made throughout this Part of BS 4479 to paint coatings. For the purposes of this standard, the term paint may be taken to include varnish in cases where the latter may be also applied by the process described.

NOTE 2 In many instances a paint system is preceded by some other surface treatment, e.g. phosphated steel or chromated aluminium, and the designer is directed to BS 4479-3 which deals with conversion coating.

NOTE 3 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 4 The titles of the publications referred to in this standard are listed on the inside back cover.
