12、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 technical committees. Each member body interested in a subject for which a technical committee
13、 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnic
14、al standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval b
15、y at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 3807 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 3807-2 was pr
16、epared by Technical Committee ISO/TC 58,Gas cylinders. This first edition, together with ISO 3807-1, cancels and replaces ISO 3807:1977, which has been technically revised. ISO 3807 consists of the following parts, under the general titleCylinders for acetylene Basic requirements: ?Part 1: Cylinders
17、 without fusible plugs ?Part 2: Cylinders with fusible plugs Annexes A to F form a normative part of this part of ISO 3807.

19、ut fusible plugs or any other safety devices; ?acetylene cylinders designed to a test pressure of at least 52 bar gauge, fitted with fusible plugs or other safety devices which release the gas and hence reduce the pressure if the cylinder temperature increases unintentionally. It was decided to spli
20、t International Standard ISO 3807 into 2 parts and specify the basic requirements of both systems separately; the differences are found mainly in the testing requirements.

23、ells made from steel and equipped with fusible plugs with a maximum nominal water capacity of 150 l. It includes the procedures for type testing, production batch testing and the methods for determining the maximum permissible settled pressure in acetylene cylinders and the porosity of the porous ma
24、ss. It also contains requirements for filling conditions of acetylene cylinders and bundles. This part of ISO 3807 does not cover acetylene cylinders with safety devices other than fusible plugs. It does not include details of design for the cylinder shell; these are specified e.g. in ISO 4705, ISO
25、4706, ISO 9809-1 or ISO 9809-3. 2Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 3807.
