In recent years in Japan, the concepts of the regulation system and technical standards have been changed a lot with following major items: 1) Changing concept of regulation from specification basis to performance basis. 2) Although specification base regulation had prescribed detailed construction, design method, applicable material and methods of inspection and testing, the performance base regulation only requires total function on reservation of safety and security. If required performance is proved on pressure equipment during manufacturing and/or operation, it will accept to use fundamentally. Performance base regulation will allow applying new technology timely but it is rather difficult in specification basis.
