AMPP CIP Level 2 case studies
AMPP CIP Level 2 · Put your knowledge to work in context.
The AMPP Coating Inspector Program (CIP) Level 2 is an intermediate-level credential within AMPP's coating inspection certification ladder, aimed at inspectors who already understand the fundamentals of protective coatings and now need to work with less supervision, interpret specifications, and resolve field questions. It suits coating inspectors, QA/QC personnel, coating applicators moving into inspection, and owner or engineering staff who witness and sign off on coating work. The AMPP CIP Level 2 case studies are 5 cases and about 3,947 words.
1The Two-Mil Disagreement on a Tank Shell
You are the third-party coating inspector on the exterior of a 250,000-gallon aboveground storage tank. The specification requires a zinc-rich primer at 3.0–5.0 mils DFT and an amine-epoxy intermediate at 5.0–7.0 mils.
