The American Society for Nondestructive Testing (ASNT) has established SNT-TC-1A, “Recommended Practice for Personnel Qualification and Certification.” This practice is used by industries through the world as a guideline for qualifying and certifying NDT personnel. As stated in TC-1A, “the effectiveness of NDT applications depends upon the capabilities of the personnel who are responsible for, and perform, NDT”. Personnel must be proficient in the nondestructive test(s) for which they are responsible. Your clients will often look at your qualification program to determine if you have taken appropriate steps to insure that your NDT staff are proficient. NDT-CGI can establish or audit your program to insure that your NDT personnel are competent and that your program meets your client’s requirements. We can also provide written and practical qualification examinations. To learn more about qualification and certification, we recommend you visit ASNT's web site and read this article.

and are conducted by TESC International / TWI Level 3 personnel qualified by examination.
