API 571 Practice Test with Latest Exam Questions 2026

API 571 Corrosion and Materials Professional is an American Petroleum Institute Individual Certification Program credential for inspectors and engineers who identify damage mechanisms in refining and petrochemical equipment. It is based on API RP 571, which describes more than sixty damage mechanisms such as wet H2S damage, high temperature hydrogen attack, sulfidation, chloride stress corrosion cracking, creep and corrosion under insulation.

The American Petroleum Institute Individual Certification Programs certify inspectors and technical personnel in refining, petrochemical and pipeline industries. API exams are computer based and are built from specific codes and recommended practices listed in each body of knowledge.

Employers and clients rely on Corrosion and Materials Professional to reduce risk, because errors in inspection, design or installation can be costly or dangerous. The credential also supports progression to senior technical or supervisory roles.

The topic areas are broad, so it helps to look inside them. The General Damage Mechanisms area includes brittle fracture, fatigue and creep. Questions on Refining Industry Damage Mechanisms typically involve sulfidation, HTHA and naphthenic acid. Environment Assisted Cracking covers SCC and wet H2S. Within Corrosion Mechanisms, candidates should be comfortable with CUI, MIC and erosion.

Preparation for API-571 works best when it mirrors the exam outline. Allow roughly 5 weeks, giving each major area its own block: begin with General Damage Mechanisms, continue with Refining Industry Damage Mechanisms, Environment Assisted Cracking and Corrosion Mechanisms, and finish with Materials Knowledge. For each area, collect key definitions, a few examples and the mistakes you made in practice, then review them weekly. Leave the final week for full timed practice tests and targeted review of weak areas.

For API-571, study the referenced standards and codes directly, tab them if open book rules allow, and practice finding requirements quickly. Work through calculation examples until you can complete them reliably.
