Re: ASNT L III vs SNT-TC-1A-L-III SNT-TC-1a allows you under your written practice to outline requirements and appoint a Level 3. Once the individual leaves that employer the certificate ceases. A Level 3 certified by ASNT is vested through examination in the individual and moves with the individual.
Some clients will not permit SNT-TC-1A appointed Levels 3 personnel.
