Specifies a number of new connections for compressed gas cylinders which fully differentiate valve outlets by gas and maximum filling pressure. The main changes are to allow specific oxygen-only connections and these are (a) the existing Type 10 connection retained for use at up to 17 500 kPa (175 bar); (b) new connection Type 10.5 to be used for up to 20 000 kPa (200 bar); (c) the existing Type 11 connection retained for use up to 25 000 kPa (250 bar); (d) new connection Type 16 to be used for up to 31 500 kPa (315 bar). Also specifies new connections for air, inert gases and high pressure flammable gases for pressures up to 31 500 (315 bar) and up to 42 500 kPa (425 bar).

This Standard specifies inlet and outlet connection threads, material, testing, valve spindle dimensions and operations, and marking requirements for compressed gas cylinder valves with threaded outlet connections for a nominated range of gases. It also specifies dimensional details of the outlet connecting parts.Appendix A specifies a special valve for use on small seamless gas cylinders filled with carbon dioxide and its future use is undecided (see Note 2).NOTES:1 Requirements for compressed gas cylinder valves, with a pin-indexed system of outlet connections (for medical application) or with a diameter-indexed system of outlet connections, are specified in AS 2472 and AS 2474.2 Comment is sought as to whether this special valve is relevant in today's industry.This Standard does not apply to valves for portable gas cylinders of less than 11 kg capacity for self-contained breathing apparatus, or to valves for fire extinguishers.NOTE: Comment is sought, especially from the 'self-contained breathing apparatus' (SCBA) industries, as to the relevance of this 11 kg capacity in today's industry.
