This standard is intended for use by coating or lining specifiers, applicators, inspectors, or others who may be responsible for defining a standard degree of surface cleanliness. The focus of this standard is near-white metal blast cleaning. White metal blastcleaning, commercial blastcleaning, industrial blast cleaning, and brush-off blast cleaning are addressed in separate standards. Near-white metal blastcleaning provides a greater degree of cleaning than commercial blast cleaning (SSPC-SP 6/NACE No. 31) but less than white metal blast cleaning (SSPC-SP 5/NACE No. 12). Near-white metal blastcleaning is used when the objective is to remove all rust, coating, and mill scale, but when the extra effort required to remove all stains of these materials is determined to be unwarranted. Staining shall be limited to no more than 5 percent of each unit area of surface. Near-white metal blast cleaning allows staining on only 5 percent of each unit area of surface, while commercial blast cleaning allows staining on 33 percent of each unit area of surface. White metal blast cleani ng does not permit any staini ng to remain on the surface. This joint standard was originally prepared in 1994 and reaffirmed in 2000 by the SSPC/NACE Task Group A on Surface Preparation by Abrasive Blast Cleaning, and NACE Unit Committee T-6G on Surface Preparation.
