ISO/TR 25107:2005 gives guidelines for non-destructive testing (NDT) training syllabuses, with the intention of harmonising and maintaining the general standard of training of NDT personnel for industrial needs. It also establishes the minimum requirements for effective structured training of NDT personnel to ensure eligibility for qualification examinations leading to third-party certification according to recognized standards. In addition to non-destructive testing in general, its guidelines for syllabuses cover acoustic emission, eddy current, leak, magnetic particle, penetrant, radiographic, ultrasonic and visual testing.
