This specification covers the requirements for the power tool cleaning of steel surfaces.
Power tool cleaning is a method of preparing steel surfaces by the use of power assisted hand tools.
Power tool cleaning removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter. It is not intended that adherent mill scale, rust, and paint be removed by this process. Mill scale, rust, and paint are considered adherent if they cannot be removed by lifting with a dull putty knife.
SSPC-VIS 3, IS0 8501-1:1988 or other visual standards of surface preparation agreed upon by the contracting parties may be used to further define the surface.
