The API Corrosion and Materials Professional blueprint is structured around these main domains:

• Other Damage Mechanisms (15%)
• Mechanical and Metallurgical Failure Mechanisms (15%)
• Terms, Definitions, and Acronyms (5%)

Additional domains complete the official outline — our question bank spans the full set.

According to the latest exam information, the API-571 exam contains 110 (100 scored, 10 unscored pretest) questions with a 195 minutes-minute limit. Since performance on the day matters as much as preparation, timed practice under these exact conditions is time well spent.

API points candidates toward these official training options:

• API RP 571 Damage Mechanisms Standard

Formal training builds the framework; consistent question practice fills it in.
