This standard contains the requirements for powertool cleaning steel to produce a commercial grade power-tool cleaned steel surface having a minimum 25 micrometer (1.0 mil) surface profile. This standard is suitable where a roughened metal surface that is free of all visible oil@ grease@ dirt@ rust@ coating@ oxides@ mill scale@ corrosion products@ and other foreign matter except as noted in Section 2.2 is required@ but where abrasive blasting is not feasible or permissible (see Notes 8.1 and 8.2). This standard differs from SSPC-SP 3@ Power-Tool Cleaning@ in that SSPC-SP 3 requires only the removal of loosely adherent materials@ and contains no requirement to expose bare metal or to achieve a minimum surface profile. This standard differs from SSPC-SP 11@ Power-Tool Cleaning to Bare Metal@ in that SSPC-SP 11 does not allow stains to remain on the surface.
