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.
