scope:

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, 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.
