Matthew Petroleum Notes

PCN Qualifications

 The PCN scheme

The PCN (Personnel Certification in Non-Destructive Testing) is a scheme for the certification of NDT technicians and supervisors and meets BS EN ISO 9712 requirements. It is founded in UK but also has an influence over many near-European countries.

What are the certification types?

There are 3 separate levels (See BS EN ISO 9712 for full details)

PCN Level 1 qualifies personnel to carry out NDT operations according to written instructions under the supervision of a Level 2 or Level 3 qualified individual. A Level 1 qualified individual has demonstrated competence to:

  • set up equipment and carry out tests
  • record and classify the results in terms of written criteria

PCN Level 2 qualifies personnel to perform and direct NDT according to established or recognised procedures and has demonstrated competence to:

  • Choose the technique for the test method used
  • Perform and supervise the test
  • Interpret, evaluate and report results according to applicable standards, codes or specifications
  • Define the limitations of the testing method for which the qualification covers
  • Understand and transform NDT standards and specifications into practical testing instructions adapted to the actual working conditions

PCN Level 3 qualifies personnel to direct any NDT operation for which they are certificated and:

  • Assume full responsibility for a test facility and staff
  • Establish and/or validate NDT instructions or procedures
  • Interpret codes, standards, specifications and procedures
  • Designate the particular test methods, techniques and procedures to be used

How useful are PCN courses and certifications?

They contain comprehensive information on NDT but will be mainly of use if you involved solely in the NDT industry. In practice a lot of PCN certificate-holders work in a practical capacity as an NDT technician

Are PCN certificates more use than API inspection qualifications?

They are a different thing. API inspector certificates provide general coverage of the inspection and integrity aspects of vessels, pipework, pipelines and storage tanks. PCN qualifications are solely about NDT.

See our article NDT and Asset Integrity; The difference to understand how the subjects differ.

See the website for details of the PCN scheme
