BS 7079:2009

This standard BS 7079:2009 General introduction to standards for preparation of steel substrates before application of paints and related products is classified in these ICS categories:

• 25.220.10 Surface preparation

This British Standard provides a general introduction to all the steel surface preparation standards. It gives general information on all the separate groups of standards, along with a complete listing of all the published standards that cover abrasive blast-cleaning, hand-and power-tool cleaning and flame cleaning of steel substrates.

This British Standard also includes definitions that are applicable to all the standards listed. Additional definitions, specific to certain processes, are given in the respective standards.

To help the user, all of the ‘older’ BS 7079 references are given so that the new and/or updated standards can easily be found, as (although some remain dual-numbered) many are now only known by their BS EN ISO reference.

Although the surface preparation standards are primarily intended for use with hot-rolled steel, abrasive blast-cleaning methods, in particular, might also be applicable to the surface preparation of cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive.

The standards are not applicable to non-ferrous substrates such as aluminium or galvanized or electroplated steel.
