9、2006(E) ISO 2006 All rights reserved iii Foreword ISO (the 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 b
10、ody 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, also take part in the work. ISO collaborates closely with the International Electro
11、technical 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 committees is to prepare International Standards. Draft International Standards adopted
12、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 possibility that some of the elements of this document may be the subject of patent r
13、ights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 6149-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. This second edition cancels and replaces the first edition (ISO 6
14、149-1:1993), 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 threads and O-ring sealing: Part 1: Ports with truncated housing for O-ring seal Part 2: Di

17、systems, power is transmitted and controlled 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 fluid conductor connectors to tubes and pipes or to hose
18、connectors and hoses. Ports are an integral part of fluid power components, such as pumps, motors, valves, cylinders, etc. For threaded 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 Intern
19、ational Standards specify ports and stud ends with metric threads and O-ring sealing and because the subcommittee would like to help 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 serie
20、s and ISO 11926 series not be used for new designs in hydraulic fluid power applications; these International Standards are maintained because they specify ports and stud ends that are currently used in hydraulic systems worldwide.

Ports in accordance w
23、ith this part of ISO 6149 may be used at working pressures up to 63 MPa 630 bar1) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO 6149-2 and ISO 6149-
24、3 for pressure ratings. Users of this part of ISO 6149 should ensure that there is sufficient material around the port to maintain the pressure.
