The Personnel Certification in Non-destructive Testing (PCN) scheme, administered by the British Institute of Non-Destructive Testing (BINDT), is one of the most widely recognized third-party NDT certifications globally. PCN is fully aligned with ISO 9712, and a PCN Level 2 certificate is accepted across Europe, the Middle East, Asia, and increasingly North America. This 2026 guide explains the PCN Level 2 exam structure, gives practice questions for the most common methods (UT, RT, MT, PT), and provides recommended study material.
\nPCN Level 2 follows ISO 9712 closely. The certification structure has three components:
\nAll three components must be passed in the same window (typically 1 year). Certification valid for 5 years with annual employer verification of practice, renewal exam at 5 years, full recertification at 10 years.
\nPCN organizes certifications by industry sector. Common Level 2 sectors include:
\nCorrect Answer: A
Explanation: BINDT, headquartered in Northampton UK, administers the PCN scheme. PCN is fully ISO 9712 aligned and accredited by UKAS (UK Accreditation Service).
Correct Answer: A
Explanation: ISO 9712 is the international standard for NDT personnel qualification. PCN is one of several ISO 9712-compliant schemes (others include COFREND, DGZfP, ACCP). EN 473 was the former European standard, now harmonized with ISO 9712.
Correct Answer: A
Explanation: ISO 9712 sets the certification cycle at 5 years initial validity, renewal at 5 years (administrative renewal with annual eye exam and continuous practice), and full recertification exam at 10 years.
Correct Answer: A
Explanation: ISO 9712 Table 2 / PCN appendix sets experience: typically 480 hours UT Level 2 documented after Level 1 certification, plus 80 hours formal training. Direct-entry Level 2 requires combined Level 1 + 2 training and experience.
Correct Answer: A
Explanation: Full skip = 2 × thickness × tan(angle) = 2 × 25 × 1.732 = 86.6 mm. Half skip = 43.3 mm. Skip distances are critical for marking the scanning range for full coverage of the weld volume.
Correct Answer: A
Explanation: European weld acceptance standards: EN ISO 11666 (acceptance for amplitude-based UT), EN ISO 23279 (characterization of indications), EN ISO 17640 (general UT of welds). ASME and AWS are also recognized depending on contract.
Correct Answer: A
Explanation: PCN RT Level 2 practical demonstration covers the full workflow: technique selection, IQI placement, exposure setup, film processing or DR/CR acquisition, interpretation, and final report. All must reach 80% to pass.
Correct Answer: A
Explanation: PCN MT Level 2 covers all magnetization techniques (yoke, prod, coil, central conductor, head shot, multidirectional), particle types (visible/fluorescent, wet/dry), field strength verification, and acceptance to applicable standards (e.g., EN ISO 23278).
Correct Answer: A
Explanation: PCN PT Level 2 practical follows the full penetrant sequence on 2 or 3 specimens (typically with planted defects). Candidates must identify and characterize indications, evaluate to the chosen acceptance standard (EN ISO 23277 etc.).
Correct Answer: A
Explanation: PCN is globally recognized in oil & gas (Shell, BP, ADNOC, Aramco accept PCN), offshore, pipelines, manufacturing, and aerospace. ISO 9712 alignment makes PCN portable across borders.
Correct Answer: A
Explanation: Per ISO 9712 / PCN, Level 2 personnel are authorized to write NDT instructions from approved procedures. The instruction is item-specific and lists exact parameters, scope, and acceptance. Level 2 cannot write procedures (that is Level 3).
Correct Answer: A
Explanation: ISO 9712 / PCN requires near vision capable of reading Jaeger 1 or Times Roman N4.5 letters at 30 cm (one or both eyes, corrected if needed), and color vision sufficient to distinguish colors used in the method (triennial test).
Correct Answer: A
Explanation: ISO 9712 specifies 10-year recertification by re-examination, similar to the initial qualifying exams. Renewal at 5 years is by document review (continued practice, eye exam, employer endorsement) with no exam.
Correct Answer: A
Explanation: ISO 9712 Annex A and PCN procedures specify the minimum 2 specimens for many sectors, with extra for multi-process sectors. Weld sector typically requires plate butt weld and pipe butt weld specimens.
Correct Answer: A
Explanation: PCN specific exams are closed-book in most sectors (candidates must memorize key acceptance values), although some sectors allow restricted reference material. Always verify with the current PCN syllabus.
Correct Answer: A
Explanation: The European/ISO acceptance standards form the spec backbone of PCN weld sector exams. Candidates must memorize quality levels (B, C, D) and key acceptance values.
Correct Answer: A
Explanation: ISO 9712 requires training by an approved training organization. PCN maintains a register of ATOs that have demonstrated trainer qualifications, syllabus alignment, and facilities. Atlantis NDT is not a PCN ATO and does not offer PCN training or preparation; its training is based on ASNT SNT-TC-1A.
Correct Answer: A
Explanation: ISO 9712 Table 1 specifies 40 hours UT Level 1 + 40 hours UT Level 2 = 80 hours total formal training. Other methods have different durations (e.g., MT 12 + 8, PT 4 + 8, RT 40 + 40).
Correct Answer: A
Explanation: PCN treats PAUT as a separate method requiring its own qualifying exam (general, specific, practical). Candidates typically must hold PCN UT Level 2 in the same sector first. See our PAUT vs TOFD article.
Correct Answer: A
Explanation: PCN is third-party certification (BINDT, not the employer, issues the certificate). ASNT employer-based (SNT-TC-1A) is issued by the employer and is tied to that employer. ASNT 9712 and ASNT Central Certification are third-party schemes. See ASNT vs PCN article.
Correct Answer: A
Explanation: Vision must be verified by an optometrist, occupational physician, or other competent medical examiner annually. Color vision is verified every 3 years. The results are recorded and submitted to BINDT.
Correct Answer: A
Explanation: ISO 9712 allows re-examination of failed components twice within the qualifying period. After two failures, re-training is required before another attempt. Practical and theory papers can be re-sat independently.
Correct Answer: A
Explanation: PCN certificate clearly states method (UT, RT, MT, PT, ET, VT), level (1, 2, 3), sector (welds, castings, etc.), holder name and ID, issue date, expiry date, and unique certificate number for verification on the BINDT portal.
Correct Answer: A
Explanation: PCN Level 3 (like ASNT Level III) requires Basic exam (cross-method knowledge) and Method exam (depth in one method). Experience after Level 2 (typically 1 to 2 years) is a prerequisite. See our Level 2 vs 3 comparison.
Correct Answer: A
Explanation: ISO 9712 / PCN Level 2 scope: equipment setup, calibration, test execution, indication interpretation, evaluation to acceptance criteria, instruction writing from procedures, training Level 1. Procedure writing and approval is Level 3 only.
A: PCN is third-party (BINDT issues the certificate). ASNT (under SNT-TC-1A) is employer-based. ASNT also offers third-party certification (ASNT 9712 / ASNT Central Certification). See our full ASNT vs PCN comparison.
\nA: Increasingly yes, especially in oil & gas and offshore. Some US codes (ASME) still default to ASNT, but PCN holders are widely accepted in international and multinational contracts.
\nA: Typically 6 to 12 months: training (1 to 2 weeks), accumulating required experience hours (often during work between training and exam), then 1 to 2 days of exams.
\nA: PCN requires continuous practice. Gaps over 12 months may invalidate certification. Always verify with BINDT and your employer.
\nA: Training fees vary (typically £1,500 to £2,500 per method) plus BINDT exam fees (~£500 to £700 per method). Total cost £2,000 to £3,500 per method.
\nA: No. PCN is run by BINDT and training is delivered by BINDT-approved Authorised Training Organisations (ATOs). Atlantis NDT does not offer PCN training or exam preparation; our training is based on ASNT SNT-TC-1A, led by an ASNT Level III, which suits candidates who also need US-recognised method qualifications.
\nA: Yes, many international inspectors hold both. They are complementary — ASNT for US work and PCN for international.
\nA: CSWIP 3.1 is a visual welding inspector qualification. PCN Level 2 weld sector is an NDT method qualification (UT, RT, MT, PT) applied to welds. Many inspectors hold both for complete fabrication inspection coverage.
\nA: First-attempt averages 60 to 75%. The practical exam has the highest failure rate. Structured prep raises pass rates to 85%+.
\nA: PCN certifies you in NDT methods. API 510/570/653 certify you as an in-service inspector of vessels, piping, or tanks. Many inspectors hold both PCN (for NDT skill) and API (for in-service inspection role).
