This European Standard specifies minimum requirements concerning material, design, construction and workmanship, manufacturing processes and testing of refillable transportable welded carbon steel gas cylinders of water capacities from 0,5 l up to and including 150 l for compressed, liquefied and dissolved gases. For acetylene service, additional requirements for the cylinder and the basic requirements for the porous mass are given in EN 1800. For those cylinders made from high frequency induction (HFI) welded steel tubes, the requirements are given in annex A. This standard is primarily for industrial gases other than LPG but may also be applied for LPG. However for dedicated LPG cylinders, see EN 1442, Transportable refillable welded steel cylinders for liquefied petroleum gas (LPG) - Design and construction prepared by CEN/TC 286 Liquefied petroleum gas equipment and accessories.
