Candidates should hold a PCN Level 2 in TOFD, a PCN Level 3 approval in Ultrasonic Testing as a minimum and have at least 3 years experience in TOFD Inspection before attempting this course.

  • PCN requirements for Level 3 approval
  • Complementary NDT methods
  • Advanced product technology
  • Quality assurance, quality control and supervision
  • Specifications, procedures and techniques
  • Analysis of reports
  • Advanced ultrasonic testing theory and revision
  • Analysis of procedures
  • Procedure writing
  • Mock examinations

An individual certified to Ultrasonic TOFD Level 3 has demonstrated competence to perform and direct Ultrasonic Testing operators for which he is certified. Ultrasonic TOFD Level 3 personnel have demonstrated:

  • The competence to evaluate and interpret results in terms of existing standards, codes, and specifications
  • Sufficient practical knowledge of applicable materials, fabrication, process, and product technology to select Ultrasonic TOFD methods, establish Ultrasonic TOFD techniques and assist in establishing acceptance criteria where non are otherwise available
  • A general familiarity with other NDT methods

Within the scope of the competence defined on the certificate, Ultrasonic TOFD Level 3 personnel may be authorised to:

  • Assume full responsibility for the test facility or examination centre and staff
  • Establish, review for editorial and technical correctness and validate Ultrasonic Testing instructions and procedures
  • Interpret codes, standards, specifications and procedures
  • Designate the particular Ultrasonic TOFD test methods, techniques and procedures to be used
  • Within the scope and limitations of any certification held, carry out all tasks at all levels
  • Provide guidance for Ultrasonic TOFD personnel at all levels

Level 3 certified personnel may be authorised to carry out, manage and supervise PCN qualification examinations on behalf of the British Institute of NDT (BINDT).

Where Level 3 duties require the individual to apply routine NDT by a method or methods within a particular product or industry sector, BINDT strongly recommends that the industry demand that this person should hold and maintain Level 2 certification in the applicable method(s) and sector(s).

The range and scope of PCN certification available at each level is defined in the relevant appendix to these general requirements.
