This standard covers the requirements for power tool cleaning to produce a bare metal surface and to retain or produce a minimum 25 micrometer (1.0 mil) surface profile.
This standard is suitable where a roughened, clean, bare metal surface is required, but where abrasive blasting is not feasible or permissible (see Notes 10.1 and 10.2).
This standard differs from SSPC-SP 3, Power Tool Cleaning, in that SSPC-SP 3 requires only the removal of loosely adherent materials and does not require producing or retaining a surface profile.
This standard differs from SSPC-SP 15, Commercial Grade Power Tool Cleaning, in that SP 15 allows stains of rust, paint, or mill scale to remain on the surface, SP 11 only allows materials to remain at the bottom of pits.
