This European Standard specifies the general requirements for filling receptacles, manifolded gas cylinders (bundles), tubes and drums with gas mixtures. Gas mixing data for some commonly used gas mixture components and further guidance notes are given in informative annexes.Filling requirements for the following are excluded from this standard:- cryogenic gases;- LPG;- beverages and other liquid foodstuffs, pressurized with carbon dioxide or other gas or previous blended gas mixture;- aerosols pressurized with a gas or previously blended gas mixture, used as a propellant;- single component liquefiable gases and liquids which have been pressurized with a gas for safety reasons or for the purpose of product withdrawal from the liquid phase.
