AMPP CAS-1 case studies
AMPP CAS-1 · Put your knowledge to work in context.
The AMPP Coating Application Specialist (CAS) is a certification offered within the Association for Materials Protection and Performance (AMPP) certification portfolio. AMPP describes itself as "the largest global community for corrosion and coatings expertise" and states that its programs "cover cathodic protection, coating inspection, protective coatings, corrosion prevention and more." The CAS credential sits in that protective coatings track and is aimed at the people who actually apply coatings in the field - applicators and application crews working on industrial and marine assets - rather than at inspectors or engineers. The AMPP CAS-1 case studies are 5 cases and about 2,520 words.
1Bridging the Holiday: Coating a Welded Joint on a Bridge
A bridge rehabilitation project requires coating a new welded joint on a steel girder. The specified coating system is a three-coat epoxy/polyurethane system with a total dry film thickness (DFT) of 250-300 μm.
