NDT Level I
An NDT Level I is qualified to perform specific calibrations, conduct specific NDT examinations following written procedures, and record results, but is not authorized to set up tests, interpret results for accept/reject, or report results without Level II/III oversight.
Definition
Level I is the entry-level NDT qualification under SNT-TC-1A, ISO 9712, and NAS 410. Training requirements typically include 24–40 hours method-specific training plus a documented period of practical experience.

Where this comes up in practice
Terms like this one appear in three places that matter commercially: the written practice that governs how your personnel are qualified, the procedures and technique sheets that define how an examination is actually performed, and the evidence an auditor or client asks for when they want to know why an inspection was accepted. Getting the terminology right is the easy part; being able to produce the qualification record, the calibration traceability and the procedure revision that applied on the day of the inspection is the part that decides audits.
Atlantis NDT provides NDT training and certification against ASNT SNT-TC-1A and ISO 9712, ASNT Level III consulting for written practices and procedure approval, inspection management software that holds qualification, calibration and procedure-revision evidence in recoverable form, and an asset integrity platform that binds inspection results to the asset they describe.
