2.3.1 SNT-TC-1A
SNT-TC-1A is a document that provides recommendations for the qualification and certifi- cation of NDE personnel. SNT-TC-1A was first published in 1967 and has been revised over the years to address the changing needs of industry. This recommended practice provides a framework for each employer to develop his own procedure or “Written Practice” for the qualification and certification of NDE personnel within his organi- zation.
