Personnel Certification in Non-Destructive Testing

The PCN scheme, an internationally recognised scheme for the certification competence of NDT personnel, is accredited as meeting the requirements of European Standards EN 45013 and EN473, and international standard ISO 9712. In addition, the aerospace sector examinations meet the requirement of EN 4179.

Certificates of competence are valid for five years from issue, following a demonstration which includes specific periods of training and experience and a thoroughly searching independent examination.

The scheme offers three levels of certification specific to industry sectors and NDT methods are defined as follows.

TWI offers the following PCN examinations at permanent locations in the UK and overseas and periodically at additional locations according to demand. Further information can be obtained by contacting TWI.
