Responsibilities of an Ultrasonic Time of Flight Diffraction (TOFD) Level 2 certified NDT professional

An individual certified to Ultrasonic TOFD Level 2 has demonstrated competence to perform NDT according to NDT procedures. Within the scope of the competence defined on the certificate, Level 2 personnel may be authorised by the employer to:

  • Select the Ultrasonic TOFD technique for the test method to be used
  • Define the limitations of application of the testing method
  • Translate Ultrasonic TOFD codes, standards, specifications and procedures into Ultrasonic TOFD instructions adapted to the actual working conditions
  • Set up and verify Ultrasonic TOFD equipment settings
  • Perform and supervise Ultrasonic TOFD tests
  • Interpret and evaluate results according to applicable standards, codes, specifications or procedures
  • Prepare written Ultrasonic TOFD instructions
  • Carry out and supervise all tasks at or below Level 2
  • Provide guidance for personnel at or below Level 2
  • Report the results of Ultrasonic TOFD tests.

Training and experience hours required for Certification

PCN Certification is awarded once the student has demonstrated the required experience and training hours have been met and successful completion of the PCN examination has been achieved:

Ultrasonic Time of Flight Diffraction
Level 2 – 40 training hours and 9 months experience

Direct access to PCN Level 2 would be achieved by combining the experience and training hours of Level 1 and Level 2:   

Direct access Level 2 – 80 training hours and 12 months experience
