23、London South Bank University, London South Bank University, Mon Apr 16 02:46:45 GMT+00:00 2007, Uncontrolled Copy, (c) BSI iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Internatio
24、nal 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, governmental and non-governmental, in liaison with ISO
25、, 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 Directives, Part 2. The main task of technical com
26、mittees 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 bodies casting a vote. Attention is drawn to the
27、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 6149-3 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar produ
28、cts and components. This second edition cancels and replaces the first edition (ISO 6149-3:1993), which has been technically revised. ISO 6149 consists of the following parts, under the general title Connections for hydraulic fluid power and general use Ports and stud ends with ISO 261 metric thread

31、d through a liquid under pressure within an enclosed circuit. In general applications, a fluid (liquid or gas) may be conveyed under pressure. Components are connected through their threaded ports by stud ends on fluid conductor connectors to tubes and pipes or to hose connectors and hoses. For thre
32、aded ports and stud ends specified in new designs in hydraulic fluid power applications, 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 subcommittee would like to hel
33、p users by recommending one preferred system. ISO/TC 131/SC 4 further recommends 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 mai
34、ntained because they specify ports and stud ends that are currently used in hydraulic systems worldwide.

36、y (L series) stud ends 1 Scope This part of ISO 6149 specifies dimensions, performance requirements and test procedures for metric adjustable and non-adjustable light-duty (L series) stud ends and O-rings. Stud ends in accordance with this part of ISO 6149 may be used at working pressures up to 40 M
37、Pa 400 bar1) for non-adjustable stud ends and 31,5 MPa (315 bar) for adjustable stud ends. The permissible working pressure depends upon the stud end size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of ISO 6149 does not guarantee
38、rated performance. Each manufacturer should perform testing according to the specification contained in this part of ISO 6149 to assure that components comply with the performance ratings. NOTE 1 A significant number of tests have been conducted to confirm the performance requirements of connection
39、ends made from carbon steel. NOTE 2 This part of ISO 6149 applies to connectors detailed in ISO 8434-1 and ISO 8434-2 (see ISO 12151-4 for related hose fitting specification). NOTE 3 The Introduction of this part of ISO 6149 gives recommendations for ports and stud ends to be used for new designs in
40、 hydraulic fluid power applications. 2 Normative references The following referenced documents are indispensable for the application of this document.
