What is SSPC SP10?
SSPC-SP 10 near-white metal blast cleaning (NACE No. 2) is a standard used for near-white metal blast cleaning put forth by the Society for Protective Coatings (SSPC) and NACE International Standard. SSPC-SP 10/NACE No. 2 removes all dust, coating, and mill scale.

What is brush blasting?
Brush-off or sweep blasting of galvanized steel is not only covered by the usual galvanizing standards. A brush-off blast cleaned surface is defined as free of all visible oil, grease dirt, dust, metal oxides (corrosion products), and other foreign matter.
What is sp10?
SP-10 is a testis-specific acrosomal protein that has been detected in several species including humans. Extracts from whole human testis and epididymal, ejaculated, and capacitated sperm were analyzed by Western blot for SP-10 polypeptides.
What is commercial blast cleaning?
Commercial blast cleaning is 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.
What is brush off blast cleaning?
What are the requirements for SSPC-SP 10 near white metal blast cleaning?
The coating specification requires that the surface has the correct roughness after applying SSPC-SP 10/NACE No. 2 for the new coating system. Therefore, the surface must be free of sharp fins, edges, weld spatter, or burning slag as indicated by the coating specification prior to performing SSPC-SP 10 near-white metal blast cleaning (NACE No. 2)
What’s the difference between SP6 and SP10 sand blasting?
The primary difference between SP 6 and SP 10 is the degree of cleanliness required from the blast cleaning. Again, these standards are minimums and should not be construed as a restriction on the usage of superior materials or procedures.
When to use near white metal blast cleaning?
Near-white metal blast cleaning is to be used to clean unpainted or painted steel surfaces prior to applying a new protective coating or lining systems. SSPC-SP 10/NACE No. 2 removes all dust, coating, and mill scale. The limit of staining permitted for near-white metal blast cleaning is no more than five percent of each unit area of the surface.
What’s the difference between SA 2.5 and SP 10?
The two versions were not equal: Sa 2.5 permitted stains, streaks and shadows from rust, mill scale and coatings to remain on up to 15% * of the surface, whereas SP 10 allowed for only 5%. In 2000, SSPC and NACE issued joint standards in anticipation of a merger between the organizations, whose memberships largely overlapped.
