When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter.
NACE 1 (SSPC-SP 5)
White Metal Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter. Random staining shall be limited to no more than 5% of each unit area of surface and may consist of light shadows, slight streaks, or minor discolorations cause by stains of previously applied coatings.

Near White Metal Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter. Random staining shall be limited to no more than 33% of each unit area of surface and may consist of light shadows, slight streaks, or minor discolorations cause by stains of rust, stains of mill scale, or previously applied coatings.
NACE 3 (SSPC-SP 6)
Commercial Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt. Traces of light adherent mill scale, rust, and coating residues are permitted to remain on 10% of each unit area of the surface if they are randomly distributed. The traces of mill scale, rust, and coating are considered tightly adherent if they cannot be removed by lifting a dull putty knife. Shadows, streaks, and discolorations caused by stains of rust, stains of mill scale, or stains of previously applied coatings may be present on the remainder of the surface.
NACE 8 (SSPC-SP 14)
Industrial Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, loose mill scale, loose rust, and loose coating. Tightly adherent mill scale, rust, and coating may remain on the surface. Mill scale, rust, and coating are considered tightly adherent if they cannot be removed by lifting a dull putty knife.

Sa 3
Blast Cleaning to Visually Clean Steel
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, and shall be free from the mill scale, rust, paint coatings, and other foreign matter. Any remaining traces of contamination will show only as slight stains in the form of spots or stripes.
Sa 2 1/2
Very Through Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, and shall be free from most of the mill scale, rust, paint coatings, and other foreign matter. Any residual contamination shall be firmly adhering.
Sa 2
Thorough Blast Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, and from poorly adhering mill scale, rust, paint coatings, and foreign matter.
Sa 1 or St 2
Sa 1 - Light Blast Cleaning
St 2 - Thorough Hand and Power Tool Cleaning
When viewed without magnification, the surface shall be free from visible oil, grease, dust, dirt, and from poorly adhering mill scale, rust, paint coatings, and foreign matter.
Sa 1 or St 2
Sa 1 - Light Blast Cleaning
St 2 - Thorough Hand and Power Tool Cleaning
Same as for St 2, but the surface shall be treated much more thoroughly to give a metallic sheen arising from the metallic substrate.
St 3
Very Through Hand and 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 a dull putty knife.
SSPC-SP 2 or SSPC-SP 3
SSPC-SP 2 - Hand Tool Cleaning
SSPC-SP 3 - Power Tool Cleaning
When viewed without magnification, shall be free from visible oil, grease, dust, dirt, coating, oxides, mill scale, corrosion products, and other foreign matter. Random staining shall be limited to no more that 33% of each unit area of surface. Staining may consist of light shadows, slight streaks, or minor discolorations caused by stains of rust, stains of mill scale, or stains of previously applied coatings. Slight residues of rust and paint may also be left in the bottom of the pits if the original surface is pitted.
SSPC-SP 15
Commercial Grade Power Tool Cleaning
A steel surface cleaned with power tools to bare metal, when viewed without magnification, shall be free from visible oil, grease, dirt, dust, coating, oxides, mill scale, corrosion products, and other foreign matter. Slight residues of rust and paint may also be left in the bottom of the pits of the original surface if the original surface is pitted.
The surface profile roughness shall be a minimum of 25.4 um (1.0 mil) as measured in accordance with Method C of ASTM D 4417 or other mutually agreed upon method. The peaks and valleys on the surface shall form a continuous pattern with no smooth unprofiled spots in between.
