13、mber 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 to be represented on that committee. International organizations, governme
14、ntal 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 Standards are drafted in accordance with the rules given in the ISO/IEC Dire
15、ctives, 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 International Standard requires approval by at least 75 % of the member bod
16、ies 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. ISO 12151-3 was prepared by Technical Committee ISO/TC 131, Fluid power systems,
17、Subcommittee SC 4, Connectors and similar products and components. This second edition cancels and replaces the first edition (ISO 12151-3:1999), which has been technically revised.

20、nclosed circuit. In general applications, the fluid can be conveyed under pressure. Components are connected through their ports by stud ends on fluid conductor connectors to tubes/pipes or to hose fittings and hoses.

30、akage or failure. 4.2 The working pressure of the hose assembly shall be the lower of the pressures given for its flange style (pressure series) and size in ISO 6162-1 or ISO 6162-2, and in the relevant hose specification. 4.3 The hose-fitting portion of a hose assembly shall be tested in accordance
31、 with ISO 19879, and the complete hose assembly shall be tested in accordance with ISO 6605. 5 Designation of hose fittings 5.1 Hose fittings shall be designated by an alphanumeric code to facilitate ordering. They shall be designated by the words “Hose fitting”, followed by a space, followed by “IS
32、O 12151-3”, followed by a spaced hyphen, then the shape symbol (see 5.2), followed by another spaced hyphen, the style letter L for 2,5 MPa to 35 MPa (25 bar to 350 bar) flanges or the style letter S for 40 MPa (400 bar) flanges in accordance with ISO 6162-1 or ISO 6162-2, followed by the flange siz
