Also known as: Level I, Level II, Level III, NDT Level 2, NDT Level 3.
What the levels mean
Both ISO 9712 and the employer-based SNT-TC-1A use three levels, with slightly different wording (Level 1/2/3 in ISO 9712, Level I/II/III in SNT-TC-1A). The level is attached to a method and, under ISO 9712, to an industrial or product sector. A UT Level 2 in welds is not automatically qualified in castings.
Why it matters on a job
Codes and client specifications state the minimum level for the person performing and the person interpreting a test, and accreditation bodies check that reports are signed by people holding the right level and scope. Sending an expired or under-qualified technician invalidates the report.
Levels in AMPS
AMPS keeps personnel and equipment certificates on dedicated personnel and equipment pages, and its flag system warns one month before a certificate, calibration document or scheduled inspection falls due, so managers always know what is missing or expiring. Supervisors can see which certificates a technician holds before allocating a job, and the history feature records who did what on every job.
