scope:

This document specifies minimum requirements concerning material, design, construction and workmanship, manufacturing processes and testing of refillable transportable welded carbon steel gas cylinders of water capacities up to and including 150 l for compressed, liquefied and dissolved gases.

For acetylene service, additional requirements for the cylinder and basic requirements for the porous mass are given in EN ISO 3807. For cylinder shells for acetylene service manufactured from high frequency induction (HFI) welded steel tubes by spinning of the end, the requirements are given in Annex A.

This document is primarily for industrial gases other than LPG but can 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.
