The information presented herein is intended to be of a general nature and so can be applied to most employer-based certification programs. It is intended for those who may not have a great deal of familiarity with the nuances of NDT certification records or programs.
Nondestructive testing (NDT, aka NDI, NDE) personnel in the United States are commonly certified in accordance with an industry specific requirement. For example, aircraft and aerospace organizations typically specify NAS 410, operating nuclear power facility regulations specify ANSI/ASNT CP-189 as modified by ASME Section XI, most other general industries fall under SNT-TC-1A and there are a number of blended and specialized requirements for specific applications. Virtually all of the above operate under some level of oversight by upper tier vendors and/or regulators.
