BS 341-3:2002 PDF

Scope: This part of BS 341 specifies requirements for the selection and dimensions of outlet connections, for valves used with transportable gas cylinders manufactured for the conveyance and storage of permanent, liquefied and dissolved gases for industrial applications. This part of BS 341 does not include requirements for the selection of valve outlets for liquefied petroleum gas (LPG), medical applications conforming to BS EN 850 or for ultra-high-purity gases used in the micro-electronics industry. This part of BS 341 applies to outlets for valves limited to a charging pressure of 300 bar (developed pressures for particular gases might exceed this pressure). A list of alternative outlets for the less commonly used gases imported into the United Kingdom is given in Annex A. note: 1) 1 bar = 10N/m = 100 kPa.
