)
Wednesday, March 08, 2023
Because SNT-TC-1A is a “recommended practice” and not a standard, there is often confusion in how it is implemented. In the recent ASNT webinar “Interpreting the SHALLS of ASNT Recommended Practice SNT-TC-1A” Antionette “Toni” Bailey takes a deep dive into the requirements in SNT-TC-1A to help Level IIIs develop their companies’ written practices.
Following are 10 key SHALL statements from SNT-TC-1A discussed by Bailey. (Statements are not verbatim from SNT-TC-1A. Emphasis added by the editor.)
The employer may alter, but “shall not eliminate” basic provisions of the program such as training, experience, testing, and recertification. (Paragraph 1.4)
The employer “shall” establish a written practice for the control and administration of NDT personnel training, examination, and certification. (Paragraph 5.1)
