Dear All,
almost all the Customer Specifications about cryogenic testing of industrial valves assume the form of an amendment and/or supplement to BS 6364 standard, an old one... but in many case the only one applicable, as of today!
(See, for reference, also thread408-148535 and thread774-127182...).
Among the many updating and additions, some Customers insert requirements about the cleanliness of the valve after cryo-testing, summoning EN 12300 standard. As far as I know, that applies to "Cryogenic vessels - cleanliness for cryogenic service" and the latest edition is dated September 2006, but I couldn't read it yet...
Is anybody able to give a quick summary of its contents?
In particular, what requirements may or may not be applied to valves?
Many THANKS in advance and regards, 'NGL
