DANSK DSF/ISO/DIS 1179-2 PDF

This part of ISO 1179 specifies dimensions, performance requirements and test procedures for heavyduty (S series) and light-duty (L series) stud ends with ISO 228-1 threads and the elastomeric sealing (type E) that is used with them. Heavy-duty (S series) stud ends with type E sealing in accordance with this part of ISO 1179 can be used at working pressures up to 63 MPa (630 bar). Light-duty (L series) stud ends with type E sealing in accordance with this part of ISO 1179 can be used at working pressures up to 25 MPa (250 bar). The permissible working pressure depends upon size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of ISO 1179 does not guarantee rated performance. It is the responsibility of each manufacturer to perform testing according to the specification contained in this part of ISO 1179 in order to ensure that components made to this part of ISO 1179 comply with the performance ratings. NOTE 1 – This part of ISO 1179 applies to connectors detailed in ISO 8434-1, ISO 8434-2, and ISO 8434-6. NOTE 2 – This part of ISO 1179 is not recommended in new designs. For threaded ports and stud ends specified in new designs in hydraulic fluid power applications the ISO 6149 series should be used. For threaded ports and stud ends specified in new designs in pneumatic fluid power applications the ISO 16030 should be used, except where products are to interface with ISO 7-1 threads.
