Selection of methods for existing and newly erected buildings. Describes main techniques in common use. Gives recommendations for the protection of buildings, operators and public.

This Part of BS 6270 gives recommendations for the cleaning of metals and alloys which are not intended to be covered with a protective coating, renewable on site in the course of maintenance.

Structural repairs are not covered by this code. Whilst in a few cases it may be possible to effect surface repairs to metals, because of the specialist nature of such processes and the wide range of metals involved, no recommendations are given in this code. No recommendations are given for the cleaning of wrought iron or mild steel which are normally provided with a protective coating.

NOTE 1 For the preparation of iron and steel surfaces prior to protective coating, reference should be made to BS 5493.

NOTE 2 Where work on features of historic or artistic importance is being considered, guidance from specialists should be sought, since the general recommendations given in this code may need to be supplemented.

NOTE 3 For guidance on the structural use of steel and aluminium, reference should be made to BS 5950 and CP 118¹⁾ respectively.

NOTE 4 Where there is any doubt about the structural nature of defects, advice should be sought from a chartered civil or structural engineer or other appropriately qualified person.

NOTE 5 The cleaning recommendations in this standard may not, in some cases, be effective against agents applied during acts of vandalism.

NOTE 6 The titles of the publications referred to in this code are listed on the inside back cover. See also Appendix A for a bibliography.
