Scope
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 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 ISO 3807. 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, LPG equipment and accessories - Transportable refillable welded steel cylinders for LPG - Design and construction prepared by CEN/TC 286 Liquefied petroleum gas equipment and accessories.
Purpose
The lower limit (of 0,5l) for the water capacity in the scopes needs to be removed, since European regulations do not have such lower limits: The industry has a need for cylinders below 0,5l water capacity, which are designed by using the relevant EN standard as guideline. But this is not the best legal way. As a result, the risk for national regulatory solutions is high.
