API 510 Certification

Pressure Vessel Inspector certification from the American Petroleum Institute for in-service inspection of pressure vessels.

American Petroleum Institute Valid: 3 years

About API 510 Certification

API 510 certifies Authorized Pressure Vessel Inspectors under the American Petroleum Institute’s Individual Certification Program (ICP). Holders are qualified to direct and perform in-service inspection, rating, repair, alteration, and rerating of pressure vessels governed by the API 510 Pressure Vessel Inspection Code — the dominant fixed-equipment integrity code in refineries, petrochemical plants, and chemical facilities. Eligibility is an education-plus-experience matrix: roughly one year of relevant supervision or inspection experience with an engineering degree, scaling up to about five years with a high-school education, and the qualifying experience must have been gained within the previous ten years under an authorized inspection program. The examination is a single 7.5-hour sitting split into a closed-book portion (recall of code requirements and inspection knowledge) and an open-book portion (applying the ASME and API documents to calculation and scenario questions) — 170 questions in total, of which 140 are scored. Certification is valid for three years; recertification requires documenting at least 24 hours of continuing professional development (CPD) and that at least 20% of working time over the cycle was spent on pressure-vessel inspection activities, with an online open-book recertification quiz required every six years.

Certification Levels

Single level - API 510 Authorized Pressure Vessel Inspector. There is no I/II/III tiering; the credential certifies the holder to apply the full API 510 code to in-service vessels.

Requirements

  • Education-plus-experience matrix (e.g. ~1 year with a relevant engineering degree up to ~5 years with a high-school diploma)
  • Qualifying experience earned within the previous 10 years under an authorized inspection program
  • Pass the 7.5-hour closed-book + open-book ICP examination (170 questions, 140 scored)
  • Working knowledge of ASME BPVC Section VIII Div 1, ASME Section V (NDE), API 510, API 571 (damage mechanisms), API 572, API 576, API 577, and API 579-1/ASME FFS-1
  • Recertify every 3 years (24 CPD hours + ≥20% time on pressure-vessel inspection); online open-book quiz every 6 years
