T/CGMA 0405-2022 Low-temperature hydrogen valve generic testing methods
Basic Information
Scope
Scope: This document specifies the terms and definitions, test items, test conditions, test media, instrumentation, test preparation, test procedures, and data processing for the performance testing of low-temperature valves for hydrogen (hereinafter referred to as "valves"). This document applies to liquid hydrogen or cold hydrogen with a medium temperature not exceeding -196°C and not lower than the boiling point of hydrogen at standard atmospheric pressure, using welded or flanged connections, with a nominal pressure not exceeding PN160 and a pressure rating not exceeding Class900, including shut-off valves, check valves, ball valves, butterfly valves, pneumatic control valves, and emergency shut-off valves.
