The Corrosion and Materials Professional (API 571) certification is a specialized credential from the American Petroleum Institute designed for professionals who need a deep understanding of damage mechanisms in the refining and petrochemical industries. The exam objectives center on the ability to identify, analyze, and mitigate over sixty distinct types of deterioration, including high temperature oxidation, sulfidation, and various forms of environmental assisted cracking. Candidates must be fluent in terminologies like hydrogen induced cracking, stress oriented hydrogen induced cracking, and morphology of damage to accurately assess equipment integrity. The curriculum emphasizes the critical factors that drive corrosion rates and the specific materials susceptible to each mechanism, ensuring that inspectors and engineers can effectively manage asset reliability.

Test takers are allotted 3 hours and 15 minutes to complete the session in a closed book environment, meaning no reference materials are permitted inside the testing center. A passing score is determined by a scaled methodology where a score of 400 on a scale of 200 to 500 is typically required for success. Effective tips include studying the API RP 571 document at least three times and using the flag feature during the test to mark difficult questions for later review without wasting valuable time.
