适用范围：This European Standard specifies the requirements for the design, manufacture and testing of valves for cryogenicservice, i.e. for operation with cryogenic fluids below - 10 ~C as well as at ambient conditions to allow for start-upand run-down. It specifies additional requirements for cryogenic service for the appropriate valve product standard.NOTE a cryogenic fluid (refrigerated liquefied gas) is a gas which is partially liquid because of its low temperature (includingtotally evaporated liquids and supercritical fluids).It applies to sizes up to DN 150 including vacuum jacketed cryogenic valves.This European Standard is not applicable to safety valves and valves for liquefied natural gas (LNG).It is intended that the valve be designed and tested to satisfy a pressure rating (PN or Class). Valves may then beselected with a PN or Class equal to or greater than the maximum allowable pressure (PS) of the equipment withwhich it is to be used.
