21、dardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right

22、 to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International S

23、tandards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an

24、International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

26、ntroduction For some applications, the contents of an individual gas cylinder may not satisfy the gas demand, in which case assemblies of cylinders can be used to supply larger volumes of gas in a single unit. The single unit, which contains a number of cylinders, is known as a cylinder bundle. A cy

27、linder bundle is a portable assembly which is designed to be routinely lifted and which consists of a frame and two or more cylinders connected to a manifold by cylinder valves or fittings so that the cylinders can be filled, transported and emptied without disassembly. A cylinder bundle can be subj

28、ected to rough handling in the course of normal operations. There are types of gas cylinder assemblies which use cylinder bundle components, but which are designed to be disassembled at each filling to enable the cylinders to be filled individually. Although these assemblies do not conform to the ba

29、sic definition of a cylinder bundle, they are commonly referred to as bundles. Their special requirements are included in Annex A. Acetylene cylinder bundles are often filled without disassembly. However, in order to confirm their solvent content, they are disassembled after a defined number of fill

30、ings. In International Standards, weight is equivalent to a force, expressed in newtons. However, in common parlance (as used in terms defined in this International Standard), the word “weight” continues to be used to mean “mass”, even though this practice is deprecated (see ISO 80000-4). ISO 2011BS

31、 EN ISO 10961:2012 EN ISO 10961:2012 (E)INTERNATIONAL STANDARD1Gas cylinders Cylinder bundles Design, manufacture, testing and inspection 1 Scope This International Standard specifies the requirements for the design, construction, testing and initial inspection of a transportable cylinder bundle. It

32、 is applicable to cylinder bundles containing compressed gas, liquefied gas and mixtures thereof. It is also applicable to cylinder bundles for acetylene. This International Standard does not apply to packages in which cylinders are manifolded together in a support frame which is designed to be fixe

33、d 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 standar

34、ds, reliability and performance, e.g. offshore cylinder bundles. Some special applications (e.g. electronics) require an alternative design approach. With the agreement of the inspection body, the manifold and its piping components may be designed and tested at a pressure which is appropriate to the

35、 service conditions. Specific requirements for acetylene cylinder bundles containing acetylene in a solvent are included in Annex B. This International Standard does not, however, cover acetylene cylinder bundles with solvent-free acetylene cylinders. This International Standard is intended primaril

36、y for industrial gases other than liquefied petroleum gases (LPGs), but it may also be used for LPGs. Unless otherwise stated, individual cylinders within cylinder bundles will have to conform to applicable standards for single cylinders. This International Standard specifies the additional requirem

37、ents that apply when individual cylinders are assembled into a bundle. 2 Normative references The following referenced documents are indispensable for the application of this document.
