Hot dip galvanizing steel articles after fabrication is one of the most widely used methods to provide corrosion protection. As a final step in the process, the hot dip galvanized coating is inspected for compliance with specifications. Correct measurement techniques and accurate interpretation of the results are necessary to provide an acceptable hot dip galvanized coating.
Conference Paper - This paper describes the requirements of the standard, additional inspection points, and several uses of the standard in the field where clear specification language was imperative to successful project completion. NACE 5/SSPC-SP 12 standard confined to water jetting - which makes use of ultra-high pressure water that is nonabrasive. Four levels of visible post-cleaning condition and three levels of non-visible condition are defined.
