The ASNT NDT Level III certification is a requirement of which documents?

The ASNT NDT Level III certification is indeed tied to both SNT-TC-1A and CP-189 documents. SNT-TC-1A serves as a guideline for developing personnel qualification and certification programs in nondestructive testing (NDT), providing a framework for training and the requirements needed to achieve certification. This document emphasizes the need for knowledge in various NDT methods and outlines the minimum requirements for Level III certification.

On the other hand, CP-189 is the standard that includes criteria for certification programs and outlines the procedures for the examination of NDT personnel. It provides a more comprehensive framework for qualification, aligning with the intent for high standards in NDT practices.

Together, these documents ensure that individuals seeking ASNT NDT Level III certification have the necessary training, experience, and knowledge to perform their duties effectively. Thus, the correct response highlights the importance of both documents in reinforcing the standards and requirements for certification in the field of nondestructive testing.
