This joint standard covers the use of blast cleaning abrasives to achieve a defined degree of cleaning of steel surfaces prior to the application of a protective coating or lining system. The focus of this standard is industrial blast cleaning, which is used when the objective is to remove most of the coating, mill scale, and rust, while the extra effort required to remove every trace of these is determined to be unwarranted. The requirements presented include the end condition of the surface and materials and procedures necessary to achieve and verify the end condition. This standard is maintained jointly by the SSPC and NACE Task Group 006.
