About this exam
The API 510 Pressure Vessel Inspector Examination assesses whether candidates can apply the API 510 in-service inspection code to pressure-vessel integrity work. It is intended for experienced inspection professionals, including engineers and other personnel involved in inspection, repair, alteration, and rerating. For an engineer, preparation means more than recalling design terminology: the exam emphasizes code-based decisions about vessel condition, inspection scope, damage mechanisms, and safe continued operation in refining, petrochemical, and other process-industry settings.
Candidates should expect questions drawn from the current API 510 Body of Knowledge and its listed publications, with exam details and permitted references set out in the current API ICP candidate bulletin. Core study areas include API 510 requirements, construction codes and design fundamentals, inspection planning, and methods for internal inspection and damage assessment. Eligibility depends on meeting API’s education and relevant experience requirements and submitting an application; requirements, exam windows, and procedures can change, so confirm them with API before applying. A structured review and realistic question practice can help reveal gaps.
How to prepare for the API 510 exam
- Start with the current API 510 Body of Knowledge and candidate bulletin. Check the listed editions and exam references, then build a study plan around the topics and publications they identify.
- Review code application alongside engineering fundamentals: inspection planning and scope, vessel construction requirements, internal inspection methods, damage assessment, and the decisions involved in repair, alteration, and rerating.
- Use timed multiple-choice practice to identify weak areas, then revisit the relevant code or reference for each missed question. Practice finding information in permitted references if the current exam format allows them.
