ASME B31.3, paragraph 342.1, specifies the requirements for examiner qualification and certification. Examiners must be certified through the employer's written practice, a quality procedure aligned with standards such as ASME, ASNT, or other recognized national or international certification programs. To achieve certification, examiners must complete the required training and demonstrate sufficient experience before passing a qualifying examination for the specific nondestructive examination (NDE) method. Once certified, examiners are authorized to perform NDE in accordance with ASME B31.3 Code requirements.
