10、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 to be represented on that c
11、ommittee. 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 Standards are drafted in acco
12、rdance 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 International Standard requi
13、res 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. ISO 1179-4 was prepared by Technic
14、al Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. This first edition of ISO 1179-4, together with ISO 1179-1, ISO 1179-2 and ISO 1179-3, cancels and replaces ISO 1179:1981 which has been technically revised. ISO 1179 consists of the foll

18、in a circuit. In general applications, a fluid may be conveyed under pressure. Components are connected through their threaded ports by fluid conductor connectors to tubes and pipes or to hose fittings and hoses. For threaded ports and stud ends specified in new designs in hydraulic fluid power appl
19、ications, ISO/TC 131/SC 4 recommends that the ISO 6149 series be used because these International Standards specify ports and stud ends with metric threads and O-ring sealing and because the sub-committee would like to help users by recommending one preferred system. ISO/TC 131/SC 4 further recommen
20、ds that threaded ports and stud ends in accordance with the ISO 1179 series, ISO 9974 series and ISO 11926 series not be used for new designs in hydraulic fluid power applications; these International Standards will be maintained because they specify ports and stud ends that are currently used in hy
21、draulic systems worldwide. For threaded ports and stud ends specified in new designs in pneumatic fluid power applications, ISO/TC 131/SC 4 recommends that ISO 16030 be used, except where products are to interface with ISO 7-1 threads, because the sub-committee would like to help users by recommendi
22、ng one preferred system. ISO/TC 131/SC 4 further recommends that threaded ports and stud ends in accordance with the ISO 1179 series not be used for new designs in pneumatic fluid power applications; these International Standards will be maintained because they specify ports and stud ends that are c
23、urrently used in pneumatic systems worldwide. Significant testing over more than 30 years of use has confirmed the performance requirements of connection ends made from carbon steel. The stud end connections specified in ISO 1179 parts 2, 3 and 4 apply to connectors detailed in ISO 8434 parts 1, 2 a

25、007(E) ISO 2007 All rights reserved 1 Connections for general use and fluid power Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing Part 4: Stud ends for general use only with metal-to-metal sealing (type B) 1 Scope This part of ISO 1179 specifies dimensions, perf
26、ormance requirements and test procedures for stud ends with ISO 228-1 threads and metal-to-metal sealing for general use only. These stud ends should not be used for leak-free hydraulic fluid power applications. Stud ends in accordance with this part of ISO 1179 may be used at working pressures up t
27、o 40 MPa (400 bar) for the S series, up to 25 MPa (250 bar) for the L series, and up to 10 MPa (100 bar) for the LL series. The permissible working pressure depends upon size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of ISO 1179
28、 does not guarantee rated performance. Each manufacturer shall perform tests according to the specification contained in this part of ISO 1179 in order to ensure that components made to this part of ISO 1179 comply with the performance ratings. NOTE 1 This part of ISO 1179 applies to connectors deta
29、iled in ISO 8434-1 and ISO 8434-2. NOTE 2 The introduction of this part of ISO 1179 gives recommendations for ports and stud ends to be used for new designs in hydraulic and pneumatic fluid power applications. 2 Normative references The following referenced documents are indispensable for the applic

34、 Requirements 5.1 Working pressure ISO 1179-4 stud ends made of low carbon steel shall be designed for use at the working pressures given in Table 2. 5.2 Performance ISO 1179-4 stud ends made of low carbon steel shall meet or exceed the burst and impulse pressures given in Table 2, when tested in ac
35、cordance with Clause 7 and assembled using the torques in Table 3. 6 Metal-to-metal sealing The machined seal edge is compressed during assembly. This causes damage to the sealing face of the port. Safe reassembly is not possible. A high surface pressure is required, otherwise leakage is possible. 7
