This document, produced by the American Society for Non-destructive Testing, is intended as a guideline for employers to establish their own written practice for the qualification and certification of their NDT personnel.
These guidelines are intended to aid employers in recognizing the essential factors to be considered in qualifying employees engaged in the major NDT methods. It’s the responsibility of the employer to establish a written practice for the control and administration of NDT personnel training, examination, and certification. The employer’s written practice shall describe the responsibility of each level of certification for determining the acceptability of materials or components in accordance with the applicable codes, standards, specifications, and procedures.
Both the training requirements and work time experience outlined inSNT-TC-1A are very similar to those stipulated in the CGSB Standard. However, instead of federally regulated certification system, such as we have in Canada, the responsibility is placed on the employer and only a level 3 individual should administer and grade examinations.
This certification is well accepted to ASME (American Society for Mechanical Engineers). API (American Petroleum Institute), AWS (American Welding Society) codes and standards.
