Alternative to BS 6364 for cryo-testing?
Alternative to BS 6364 for cryo-testing?
(OP)
Excluding EN 1626 which is not applicable to LNG applications and over DN150, the only international standard about cryogenic testing of valves that I know is BS 6364; and all the project or Engineerings' specifications (e. g.: from Shell, Bechtel, Chyioda, C.B.&I. and so on...) refer to that.
This standard dates back to 1982 in its general formulation and back to 1998 in its last amendment about tests.
Is anybody aware of a different cryo-test standard?
Has anybody ever felt the need of a new, alternative reference?
Please refer also to the considerations arose within the thread774-127182!
Thanks to All, 'NGL

Has anybody got any further information about that?
Maybe the job was re-assigned to ISO TC 220 (technical comcommittee for industrial Valves)?

RE: Alternative to BS 6364 for cryo-testing?
I am also in the valve business (manufacturing) and sell a lot of valves for cryogenic applications (cold boxes & LNG) but my customers have always viewed the Appendix A of BS 6364 as a "prototype" test. We have always set this type of test up in the laboratory.
I do not know of any other cryogenic valve standard that is under development nor do I know of any standard commercial valve manufacturer that performs cryogenic testing as a production routine. Perhaps, manufacturers of high-end cryogenic laboratory valves.
If you see this type of testing becoming routine I will be very interested in your comments.
