Alternative to BS 6364 for cryo-testing?

Alternative to BS 6364 for cryo-testing?

Alternative to BS 6364 for cryo-testing?

      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

RE: Alternative to BS 6364 for cryo-testing?

     I heard about an ISO/DIS 21011 draft standard which was under development by ISO TC 220 (technical comcommittee for Cryogenic Vessels), but I found that the relevant project was deleted (on February 2006):

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

Thanks to all,    'NGL


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.
