ISO 10297:2024

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 is acting as the primary valve operating mechanism (VIPR type B). This also includes designs where closure of the primary valve operating mechanism is obtained by closing the seat of the pressure regulating mechanism.

2)  The primary valve operating mechanism 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, VIPRs and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.

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 contains normative references to this document;
