This International Standard 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), non-return valves or ball valves.NOTE 2 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level e.g. in EN 1626. Requirements for LPG valves are specified in ISO 14245 or ISO 15995. Requirements for quick-release valves are specified e.g. in ISO 17871. Requirements for valves for portable fire extinguishers at a regional level are specified e.g. in EN 3 series. Requirements for non-return valves and ball valves might be specified in international/regional standards.NOTE 3 Requirements for manufacturing tests and examinations of valves covered by this International Standard are given in ISO 14246.NOTE 4 Additional requirements for VIPR are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Additional requirements for residual pressure valves with or without a non-return function are specified in ISO 15996. Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.
