ASNT Standards: Elevating NDT Personnel

Setting global benchmarks for nondestructive testing excellence and professionalism.

ASNT Standard on AI/ML in NDT/E Update
ASNT invited public comment on its proposed standard Use of AI/ML for NDT/E Applications, which sets minimum requirements for developing, validating, deploying, and maintaining AI/ML in the NDT/E field. The review period (30 May–14 July 2025) is now closed, and submitted comments are under consideration by the ASNT Standards Council.

At ASNT, we are committed to establishing and upholding the highest standards for the qualification and certification of nondestructive testing (NDT) personnel. Our standards and recommended practices serve as the foundation of excellence, guiding the NDT community toward unmatched expertise and professionalism.

Developed by expert ASNT committees, these standards define the qualifications required for NDT personnel to meet the rigorous demands of industries and governments worldwide. By adhering to these standards, NDT professionals enhance their careers while ensuring the reliability and safety of the industries they serve.
