NBN EN 13769:2003

This European Standard specifies the requirements for the design, manufacture, identification and testing of a cylinder bundle. It is applicable to cylinder bundles containing compressed gas, liquefied gas and mixtures thereof. It is also applicable to cylinder bundles for acetylene.
This European Standard does not apply to packages in which cylinders are manifolded together in a support frame which is designed to be fixed permanently to a road vehicle to a railway wagon or to the ground as a customer storage vessel. It does not apply to cylinder bundles which are designed for use in extreme environmental or operational conditions when additional and extraordinary requirements are imposed to maintain safety standards, reliability and performance. Offshore cylinder bundles are a specific example.
NOTE The specific requirements for acetylene are included in annex B.
This standard is primarily for industrial gases other than Liquefied Petroleum gases (LPG) but may also be used for LPG. However for dedicated LPG cylinders, see standards prepared by CEN/TC 286 Liquefied petroleum gas equipment and accessories.
