Scope

Scope: This document specifies the terms and definitions, structural types, technical requirements, materials, performance requirements, inspection and testing, inspection rules, marking, packaging, and storage requirements for shut-off valves and check valves (hereinafter referred to as "valves") used in liquid hydrogen media. This document applies to shut-off valves and check valves with nominal pressures of PN16 to PN150, nominal sizes of DN15 to DN300, pressure classes of Class150 to Class900, nominal sizes of NPS1/2 to NPS12, and media temperatures not exceeding -196°C and not lower than the boiling point of hydrogen at standard atmospheric pressure, which are welded or flanged-connected.
