This standard contains the requirements for powertool cleaning steel to produce a bare metal power tool cleaned surface having a minimum 25-micrometer (1.0-mil) surface profile. This standard is suitable where a roughened@ clean@ bare metal surface free of all visible oil@ grease@ dirt@ rust@ coating@ oxides@ mill scale@ corrosion products@ and other foreign matter 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 the removal of loosely adherent materials only@ and contains no requirement to expose bare metal or to achieve a minimum surface profile. This standard differs from SSPC-SP 15@ Commercial Grade Power-Tool Cleaning@ in that SSPC-SP 15 allows stains to remain on the surface.
