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).
