1 Scope This document specifies the terms and definitions, basic types, technical requirements, inspection and test methods, inspection rules, marking, packaging, transportation, storage, product certificate and product batch inspection quality certificate of gas cylinder valves. This document is applicable to valves (hereinafter referred to as valves) for compressed, liquefied and dissolved gas cylinders with ambient temperature of -40°C to +60°C, nominal working pressure not greater than 35 MPa, transportable and refillable. This document is not applicable to the valves on welded thermal insulation cylinders, fire-fighting cylinders, vehicle cylinders, respirator cylinders, LPG cylinders, liquefied dimethyl ether cylinders and industrial non-refillable welded steel cylinders. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
