20、I BS EN ISO 14113:2008 ISO 14113:2007(E) iv ISO 2007 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO tec
21、hnical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closel
22、y with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards 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
23、International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an 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 documen
24、t may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14113 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 8, Equipment for gas welding, cutting and allied processes. This second editi
25、on cancels and replaces the first edition (ISO 14113:1997), which has been technically revised. Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 8 via your national standards body, a complete listing of which can

27、or use with industrial gases up to 450 bar (45 MPa) 1 Scope This International Standard specifies requirements for rubber and plastics hose and hose assemblies for use with compressed, liquefied and dissolved gases up to a maximum working pressure of 45 MPa (450 bar), within the ambient temperature
28、range of 20 C to +60 C. This International Standard applies to hose assemblies used to connect industrial gas cylinders to manifolds or bundles prior to any pressure reduction stage. This International Standard does not cover rubber or thermoplastic hoses for welding, cutting and allied processes (s
29、ee ISO 3821 and ISO 12170). This International Standard does not apply to refrigerated liquefied gases or to liquefied petroleum gases (LPG). 2 Normative references The following referenced documents are indispensable for the application of this document.

37、curs when subjected to oxygen pressure and heating, and in the absence of a source of ignition other than the applied temperature NOTE The autogenous ignition temperature depends on the sample preparation, test apparatus and test procedure employed. 3.2 burst pressure pressure at which rupture of th
38、e hose occurs when tested to the relevant standard ISO 8330:2007, 2.1.21 3.3 distant piece length of metallic tubing at the end of a hose or hose assembly that serves to contain and cool the highest temperature gas that is formed by the effect of adiabatic compression, e.g. by the rapid opening of a
39、 cylinder valve 3.4 end fitting subassembly of components enabling the hose to be safely connected to other pressurised equipment 3.5 hose assembly length of hose with suitably attached end fittings 3.6 maximum working pressure pressure to which a hose is designed to be subjected during service, inc
40、luding expected momentary surges NOTE 1 This definition is consistent with that for a gas cylinder in ISO 10286:2007, A.2.4 maximum permissible operating pressure (the highest pressure permitted to be developed during service). ISO 10286:2007 defines “working pressure” as the “settled pressure . at
41、a uniform . temperature of 15 C in a full gas cylinder”. NOTE 2 Due to the peculiar characteristics of the acetylene cylinder, there is no clearly defined maximum working pressure for acetylene service. Applicable requirements for acetylene service are given in relevant clauses. Licensed Copy: Londo

43、onstruction NOTE It is expressed in bars. ISO 8330:2007, 2.1.104 4 Construction 4.1 Hose The hose should consist of either: a rubber or plastics lining, reinforcement consisting of one or more layers, and an outer protective cover of permeable material or perforated rubber or plastics, for flammable
44、 gas service, the hose shall also incorporate bonding wires to provide the electrical conductivity, see 7.8; or: a rubber or plastics lining, and reinforcement consisting of one or more layers of stainless steel wire braid and/or other corrosion and abrasion resistant material which is also designed
45、 to act as an outer protective cover and provide electrical conductivity, see 7.8. 4.2 End fittings Fittings shall be of permanent, swage or crimp design. The fitting design shall enable the hose assembly to attain its burst pressure without fitting pullout or separation from the hose. End fittings
46、shall be manufactured from materials that are compatible with the gases and the environment to which they will be subjected, e.g. according to ISO 9539. 4.3 Hose assemblies Assemblies shall consist of a length of hose and permanently attached end fittings. Field-attachable or reusable-type fittings
47、shall not be used. Distant pieces, when used as heat sinks as part of hose assemblies for oxygen service (see 7.1.3) shall not be readily detachable by the user. For maximum working pressures in excess of 40 bar (4 MPa), hoses assembled should be provided with a suitable restraining cable or device,
48、 properly fitted to an anchor point to restrain the hose in the event of a hose assembly failure.

49、lerances 5.1 Bore size The bore of the hoses shall be in accordance with the nominal bore sizes and permitted ranges given in Table 1, except that the effective maximum bore of hoses for acetylene shall not exceed 25 mm. NOTE In some countries, local regulations can restrict bores of acetylene hoses to less than 25 mm. 5.2 Concentricity The internal diameter and concentricity of the hose, measured according to ISO 4671, shall be in accordance with the values given in Table 1.
