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.
