Special conditions for bundles, disassembled at the time of filling, includingacetylene.14Annex B (normative)
Specific requirements for acetylene cylinder bundles.15Bibliography.22SIST EN 13769:2004

These assemblies do not conform tothe basic definition of a cylinder bundle, however, they are commonly referred to as bundles. Their specialrequirements are included in annex A.Acetylene cylinder bundles are often filled without disassembly, however, in order to confirm their solvent contentthey are disassembled after a defined number of fillings.Unless otherwise stated, individual cylinders within cylinder bundles should conform to applicable standards forsingle cylinders. This standard specifies the additional requirements that apply when individual cylinders areassembled into a bundle.SIST EN 13769:2004

Definitions specific toacetylene are included in annex B.SIST EN 13769:2004

not exceeding 5 000 ml/m³4 Design4.1 GeneralThe design of the bundle shall take into consideration its construction and inspection as well as its operation. Allpressurized components shall be designed to operate safely in the temperature range of – 20 °C to + 65 °C. Theyshould also be designed to withstand local temperature conditions outside this range.Bundles which are filled by weight shall not feature component parts which are de-mountable without the use oftools, with the exception of the main valve outlet protection cap.4.2 Frame4.2.1The frame shall retain securely all the components of the bundle and shall protect them from damagewhich might cause leaks. Such damage can be caused by vibration, impact loads or handling loads which can beexperienced in normal operation. The method of cylinder restraint shall prevent any vertical or horizontal movementor rotation of the cylinder which would impose undue strain on the manifold (see 7.2.2). The total assembly shall becapable of withstanding rough handling, including being dropped or toppled.Additionally no leakage of gas shall be caused during the lifting of the bundle (see 4.2.2).SIST EN 13769:2004

Bundles with morethan one lifting eye shall be designed such that a minimum sling leg angle of 45° to the horizontal can be achievedduring lifting using the lifting eyes.Where four lifting eyes are used their design shall be such that they are strong enough to allow the bundle to belifted by only two.Where two or four lifting eyes are used, diametrically opposite lifting eyes shall be aligned with each other to allowfor correct lifting using shackle pins.Where a bundle is moved by fork-lift truck it shall feature two fork apertures on each side it is to be lifted from. Thefork apertures shall be positioned symmetrically about the centre of gravity and their size shall be appropriate to theforks which are to be used to move the bundle. The fork apertures shall be designed such that the bundle cannotaccidentally disengage from the forks.4.2.3Frame structural members shall be designed for a vertical load of 2 x the maximum gross weight of thebundle. Design stress levels shall not exceed 0,9 x the yield strength of the material.4.2.4The frame design shall ensure that there are no protrusions from the exterior frame structure which couldcause hazards.4.2.5There shall be no features in which water and debris can collect to increase the tare weight of bundles filledby weight.4.2.6The floor of the bundle frame shall not buckle during normal operational conditions and shall facilitate thedrainage of water and debris from around the base of the cylinders.4.2.7The design shall ensure stability under normal operating conditions.4.2.8If the frame design includes any movable doors or covers then these shall be capable of being secured inposition with latches, which shall not be capable of being dislodged by operational impact loads.4.2.9Access shall be maintained to all valves which need to be operated in normal service or in an emergency.4.2.10Each frame shall include a unique identification number which shall be permanently marked.4.3 CylindersCylinders within a bundle shall be suitable for the gas type. They shall all have the same test pressure and shallconform to the appropriate standards covering individual cylinders.4.4 Cylinder valves/cylinder fittings4.4.1Either a cylinder valve or a cylinder fitting shall be fitted into the necks of cylinders within the bundle, thechoice of item being determined by the gas product within the bundle and operational requirements.For acetylene see annex B.4.4.2Cylinder valves and cylinder fittings shall be compatible with the gas and pressure for which the bundle isintended.4.4.3Cylinder valves and cylinder fittings shall be compatible with the neck of the cylinder.4.4.4A cylinder valve shall be used where the bundle contains toxic gas or gas mixture with an LC50
of less than200 ppm (ml/m3), pyrophoric gas, or flammable mixtures with more than 1% of pyrophoric components. A cylindervalve shall not be used for non toxic liquefied gases, unless the valve is permanently locked open.SIST EN 13769:2004

Flexible hoses or non-metallic pipework should only be used as part of the fixed pipework on the bundle aftertrials have proved their acceptability, and the length of such hoses and pipework shall be kept to a minimum.4.6 Main connection(s)The main connection(s) shall be compatible with the gas and the pressure for which the bundle is intended andshall be protected by the frame; i.e. the valve shall not protrude.5 ManufacturingA bundle shall be manufactured in accordance with the design criteria listed in clause 4.For this condition to be satisfied the manufacturer shall:¾ use welding procedures in accordance with EN 288-1;¾ use approved welders in accordance with EN 287-1;¾ use brazing procedures in accordance with EN 13134;¾ use approved brazers in accordance with EN 13133.6 Identification6.1 GeneralA bundle design can include components which protect the manifold and which can cause an obstruction to theview of the shoulders of the cylinders. Therefore the requirements for labelling and colour coding as defined inEN 1089-2 and EN 1089-3 do not apply to bundles, except for acetylene see annex B.Additionally, markings on the individual cylinders can also be obscured, therefore certain information whichrequires to be checked at the time of filling shall be duplicated on the outside of the bundle, see 6.3.
