14、dard 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 commercial blast cleaning. White metal blast cleaning, near-white metal blast cleaning, industrial b

15、last cleaning, and brush-off blast cleaning are addressed in separate standards.Commercial blast cleaning provides a greater degree of cleaning than industrial blast cleaning (SSPC-SP 14/NACE No. 81) but less than near-white metal blast cleaning (SSPCSP 10/NACE No. 22). Commercial blast cleaning is

16、used when the objective is to remove all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter, leaving staining or shadows on no more than 33 percent of each unit area of surface.The difference between a commercial blast cleaning and a near

17、-white metal blast cleaning is in the amount of staining permitted to remain on the surface. Commercial blast cleaning allows stains or shadows on 33 percent of each unit area of surface. Near-white metal blast cleaning allows staining or shadows on only 5 percent of each unit area of surface.注意事项：应

20、灰尘、污物、氧化皮、绣、涂料、氧化物、腐蚀产品及其他杂质，使着色或阴影部分不超过各单元表面积的33%.商业级和近似出白级金属喷砂清理喷砂清理的区别在于：允许表面残留着色的数量，商业级喷砂清理允许表面残留的着色或阴影不得超过各单元表面积的33%；而近似出白级金属喷砂清理允许表面残留的着色或阴影不得超过各单元表面积的5%。The difference between a commercial blast cleaning and an industrial blast cleaning is that a commercial blast cleaning removes all visible

21、oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter from all surfaces and allows stains to remain on 33 percent of each unit area of surface, while industrial blast cleaning allows defined mill scale, coating, and rust to remain on less than 10 pe

22、rcent of each unit area of surface and allows defined stains to remain on all surfaces.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. This joint task group includes members of both the SSPC S

23、urface Preparation Committee and the NACE Unit Committee T-6G on Surface Preparation. It was reaffirmed in 2006 by the SSPC Surface Preparation Committee and NACE Specific Technology Group (STG) 04, Protective Coatings and Linings: Surface Preparation.In SSPC/NACE standards, shall and must are used
