\nGeneral Specifications of Gas Cylinder Valves<\/p>\n
\n1 SCOPE<\/p>\n
This Standard specifies the terms and definitions, specifications, type test, inspection, pass criteria, marking, packaging, transportation and storage as well as quality certificate of gas cylinder valves.
\nThis Standard applies to the valves (hereinafter referred to as \u201cvalves\u201d) intended to be fitted to transportable and refillable gas cylinders which convey compressed, liquefied or dissolved gases with a nominal operating pressure \uf0a330 MPa at an ambient temperature range of -40\u00b0C to +60\u00b0C.
\nThis Standard doesn\u2019t apply to the valves intended for cryogenic equipment, fire extinguishers, automotive liquefied petroleum gas (LPG) cylinders, automotive compressed natural gas (CNG) cylinders, breathing gas cylinders or non-refillable cylinders. This Standard also doesn\u2019t cover the specific requirements for gas cylinder valves fitted with pressure-reducing devices, residual pressure-retaining devices or non-return devices.<\/p>\n
