scope:

NEN-EN-ISO 10297 specifies design, type testing and marking requirements for: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for cylinder bundles; c) cylinder valves or main valves with integrated pressure regulator (VIPR); which convey compressed, liquefied or dissolved gases. NOTE 1 Where there is no risk of ambiguity, cylinder valves, main valves and VIPR are addressed with the collective term "valves" within this International Standard. This International Standard covers the function of a valve as a closure. This International Standard does not apply to - valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG), and - quick-release valves (e.g. for fire-extinguishing, explosion protection and rescue applications), nonreturn valves or ball valves.
