The API-510 exam is the official assessment behind the API Pressure Vessel Inspector certification from API, and its pass rate is genuinely low — many candidates need two or three attempts to get through. The difficulty is real, but it is also manageable: candidates who prepare with material aligned to the published objectives give themselves a far better starting position than those who walk in underprepared.
Registration for the API-510 exam runs through these official channels:
Given how commonly this exam takes more than one attempt, schedule your sitting only when your practice results say you are ready.
The official outline divides the API-510 exam into weighted domains, including:
- Damage Mechanisms and Corrosion Assessment (22%)
- Fitness-for-Service, RBI, and Pressure Testing (12%)
- Inspection Scope, Planning, and Data Evaluation (28%)
The API Pressure Vessel Inspector question bank at ValidTorrent is updated daily against these same objectives, and the free practice test lets you sample that alignment yourself.
API recommends these training resources for candidates:
Official training builds the foundation; a daily-reviewed practice bank with expert-verified answers builds the exam-day readiness. Use both.

Passing the API-510 exam requires 550 (scaled score, range 200–750), and registration costs $875 (API member) / $1,125 (non-member) USD — per attempt. With retakes so common on this exam, preparing properly for one focused attempt is the choice that protects your budget.
The API-510 exam contains 170 (140 scored + 30 unscored pretest; 110 closed-book + 60 open-book) questions with 450 (total exam day: 7.5 hours; 165 min closed-book + 225 min open-book + 45 min break) minutes to complete them.

API Pressure Vessel Inspector Sample Questions:
Question #1
Explain the API-510 provisions regarding the frequency and extent of inspections required after a pressure vessel has been altered or repaired.
Reveal Solution Discussion 0Correct Answer:
API-510 requires that pressure vessels undergo rigorous inspections following any repairs or alterations to ensure the integrity of the vessel is maintained. The standard stipulates that these vessels should be inspected immediately after the work is completed and before they are returned to service.
The type of inspection can vary but typically includes non-destructive testing (NDT) to verify the quality of the repair or alteration and to confirm that no additional damage was introduced during the process.
Question #2
Discuss the implications of deferred maintenance on pressure vessels and how API-510 helps to mitigate these risks.
Reveal Solution Discussion 0Correct Answer:
Deferred maintenance on pressure vessels can lead to serious safety risks, including the potential for catastrophic failures. API-510 mitigates these risks by setting strict guidelines for inspection and maintenance schedules based on the condition and service history of the vessels. The standard emphasizes the importance of adhering to these schedules and provides criteria for risk-based inspections that prioritize maintenance tasks based on the urgency and potential impact of defects. This proactive approach helps prevent the deterioration of vessel condition and ensures that maintenance is performed before any serious issues arise.
Question #3
Outline the process and requirements for the decommissioning and safe disposal of pressure vessels according to API-510.
Reveal Solution Discussion 0Correct Answer:
Decommissioning a pressure vessel under API-510 involves a thorough cleaning to remove hazardous substances, a final inspection to document the vessel's condition, and ensuring all environmental regulations are met during disposal. The vessel may need to be dismantled in a controlled manner, especially if it contained toxic or radioactive substances. Documentation of the decommissioning process is crucial for compliance and environmental protection.
Question #4
Increasing hardness of the metal substrate is not always a good indicator of improved resistance to
__________, particularly where corrosion plays a significant role.
- A. stress corrosion cracking
- B. ductile failure
- C. stress corrosion
- D. erosion
Correct Answer: D 🗳️
Question #5
What does API-510 require to verify a welder's qualifications when welding on a pressure vessel?
- A. Inspection of previous work
- B. A written test
- C. A practical demonstration
- D. Performance qualification records
Correct Answer: D 🗳️
