A Study on the International Standards of Performance Testing Method of Valves for Cryogenic Service There

There have not been international standards about the test evaluation for cryogenic valves so far. It just follows local or organization standards at the moment. To develop the international standard of cryogenic test method and procedure, we have studied domestic and international techniques and trends about the test method. We also have attended international conference meetings and seminars for technical agreement of the standard procedure and test method. The standard procedure has been revised by analysing a lot of test results using the standard test method. Finally we try to register the test method for cryogenic valves as an international standard through activities in the international working group or international conference meetings. In this paper, the results of the ISO international conference meeting(ISO/TC 153) at Canada are briefly presented.
