AMPP PCS case studies
AMPP PCS · Put your knowledge to work in context.
The AMPP Protective Coatings Specialist (PCS) is a professional credential offered within the certification portfolio of AMPP, the Association for Materials Protection and Performance. 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 PCS credential sits on the protective coatings side of that portfolio, which makes it relevant to personnel who specify, apply, supervise, or verify protective coating systems on industrial assets rather than to cathodic protection specialists. Candidates typically include coatings applicators and supervisors, coating inspectors, quality personnel, and engineers or asset owners who need a working command of coating system selection, surface preparation, application variables, and inspection and testing practice. The AMPP PCS case studies are 5 cases and about 2,235 words.
