Recommended Practice
SNT-TC-1A (2001 Edition)

The American Society for Nondestructive Testing (ASNT) Recommended Practice No. SNT-TC-1A had its beginning in the early 1960's. The Society for Nondestructive Testing (SNT at that time) Board of Directors charged the Technical Council to develop a set of guidelines which could be used by employers to develop their own "In -house" employer based training, qualification and certification programs.
