Abstract: A brief analysis is made on the current laboratory accreditation situation for the competence of time of flight diffraction ultrasonic (TOFD) testing in China. The current standards in the field of TOFD are compared in detail for the requirements on personnel qualification and equipment calibration and checking. Based on the understanding of special aspects of TOFD and the situation of its application in China,some suggestion on personnel, equipment and control of technique for the laboratory accreditation of TOFD competence are proposed.
