10、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 has been established has t
11、he 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 electrotechnical standardization. Interna
12、tional 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 International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicatio
13、n 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights

In general applications,
17、a fluid can 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 fittings and hoses. Fluid ports are closed by inserting a plug in the port. -,-,- INTERNATIONAL STANDARD ISO 6149-4:2006(E) ISO 2006
18、All rights reserved 1 Connections for fluid power and general use Ports and stud ends with ISO 261 metric threads and O-ring sealing Part 4: Dimensions, design, test methods and requirements for external hex and internal hex port plugs 1 Scope This part of ISO 6149 specifies dimensions and performan
19、ce requirements for external hex and internal hex port plugs for use with ISO 6149-1 ports. Port plugs in accordance with this part of ISO 6149 can be used at working pressures up to 63 MPa (630 bar1). The permissible working pressure depends upon the plug end size, materials, design, working condit
20、ions, application, etc. Conformance to the dimensional information in this part of ISO 6149 does not guarantee rated performance. It is necessary that each manufacturer perform testing according to the specification contained in this part of ISO 6149 to assure that components comply with the perform
21、ance ratings. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
