概要
The PD Center of Central Research Institute of Electric Power Industry (CRIEPI) commenced Per formance Demonstration examinations for flaw depth sizing of austenitic stainless steel pipes n March 2006. At the end of FY 2013, 40 examination sessions have been completed and 49 cand ates have passed the examination. The total number of tests administered including re-tests and re-certification was 95. It was noted that the final call for the crack length (PD examin ation answer) was adopted the phased array method rather than the manual UT method. Furthermo , it was supposed that the availability for identification the reason of PD examination fail e has an effect on the passing a re-testing from an analysis of the PD examination results.
