This part of ISO 6149 specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends detailed in ISO 6149-2 and ISO 6149-3.
Ports in accordance with 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 6149-3 for pressure ratings.
Users of this part of ISO 6149 should ensure that there is sufficient material around the port to maintain the pressure.
NOTE The Introduction of this part of ISO 6149 gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications.
1) 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
