A second method of measuring a blast profile is a digital gauge depth micrometer.

What do you need to know about SSPC-SP 3?

SSPC-SP 3 is power tool cleaning, which is a method of surface preparation on steel surfaces with the use of power assisted hand tools. It is performed after SSPC-SP 1, solvent cleaning. Power tool cleaning is to remove loose rust, mill scale, and paint. The power tools used for this standard include sanders, wire brushes or wheels,

Which is better SSPC-sp 5 or NACE No.1?

SSPC-SP 5/NACE No. 1 removes all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and any other foreign matter on the surface. Therefore, it is often better than other blast cleaning as it requires higher standards of a clean surface.
