This document 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 bundles of cylinders;
c) cylinder valves or main valves with integrated pressure regulator (VIPR);
NOTE 1 This includes the following specific VIPR designs where:
1) the pressure regulating system of a VIPR is acting as the primary valve operating mechanism (VIPR type B). This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating mechanism.;
2) the primary valve operating mechanism of a VIPR is located at the low pressure side of the pressure regulating system (VIPR type C).
d) valves for pressure drums and tubes;
which convey compressed, liquefied or dissolved gases.
NOTE 2 Where there is no risk of ambiguity, cylinder valves, main valves, VIPR and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.
NOTE 3 The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.
This document does not apply to
— valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG);
— quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which nevertheless contains normative references to this document;
— self-closing cylinder valves or ball valves.
NOTE 4 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 self-closing cylinder valves are specified in ISO 17879. Requirements for ball valves are specified in ISO 23826. Requirements for valves for portable fire extinguishers at a regional level are specified e.g. in EN 3 series.
This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document.
NOTE 5 Definition and specific requirements for VIPR in addition to those that are given in this document are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Similarly, certain specific requirements for residual pressure valves (RPV) with or without a non-return function in addition to those that are given in this document are given in ISO 15996.
NOTE 6 Certain specific requirements for valves for breathing apparatus in addition to those that are given in this document are specified at a regional level, e.g. in EN 144 series. Certain specific requirements for quick-release valves for fixed fire-fighting systems in addition to those that are given in this document are specified in ISO 16003 and at a regional level e.g. in EN 12094–4.
NOTE 7 Additional requirements for pressure-relief devices can exist in international/regional regulations/standards.
NOTE 8 Requirements for manufacturing tests and examinations of valves covered by this document are given in ISO 14246.
