Selected Answers

From Yan Lin, Yu of DNVGL on November 23, 2017:
It's a good question, but there is no answer at this moment. The answers already given are not the right ones, because ASTM A- 380 is not for inspection of surface cleanness prior to paint application; and in SSPC-SP 16, roughness is not standard of cleanness.

From Bryant Chandler of Greenman-Pedersen, Inc. on November 17, 2017:
Performing a passivation treatment on the SST will remove contaminants. Passivation is normally done with nitric acid or other organic acids. Consult ASTM A380, which describes 8 cleaning/passivation treatments and 4 cleaning treatments using other chemicals. Do not use a chlorinated solvent as chlorides can lead to stress corrosion cracking.

From Jithin Narayanan of JGC Corporation on November 12, 2017:
Visually, it is impossible to distinguish SSPC-SP7/ SP10/SP5/ SP16 if new stainless steel is blasted. The profile can be verified using conventional methods. The presence of contaminants such as surface salt and dust can be determined using conventional methods.
