This International Standard establishes a system for the qualification and certification, by a certification body, of personnel to perform industrial non-destructive testing (NDT) using any of the following methods:

- eddy current testing;

- liquid penetrant testing;

- magnetic particle testing;

- radiographic testing;

- ultrasonic testing.

The system described in this International Standard may also apply to visual inspection (VT), leak testing (LT), neutron radiography (NT), acoustic emission (AT) and other NDT methods where independent certification programs exist.

Where latitude is provided in the criteria within this International Standard, the certification body shall have the final decision in determining specific requirements.
