概要
The PD Center at the Central Research Institute of Electric Power Industry (CRIEPI) commenced Performance Demonstra tion examinations for flaw depth sizing of austenitic stainless steel pipes in March 2006.

Many candidates failed th e PD examination due to a failure to distinguish between crack tip echo and echo from weld to base-metal interface.
