This part of ISO 11926 specifies dimensions for ports with inch threads complying with ISO 725 for use with the adjustable and non-adjustable stud ends detailed in ISO 11926-2 and ISO 11926-3. It also specifies test methods and the designation of these ports.
Ports in accordance with this part of ISO 11926 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 the port size, materials, design, working conditions, application, etc.
For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, only ISO 6149 is to be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974 and ISO 11926 are not to be used for new designs in hydraulic fluid power applications.
1) 1 bar = 0,1 MPa = 105Pa; 1 MPa = 1 N/mm2
