scope:

This part of ISO 9974 specifies dimensions, performance requirements and test procedures for heavy-duty (S series) and light-duty (L series) stud ends with ISO 261 threads and the elastomeric sealing that is used with them, it also specifies the designation of these stud ends and their elastomeric sealing.

Heavy-duty (S series) stud ends with type E sealing in accordance with this part of IS0 9974 may be used at working pressures up to 63 MPa (630 bar I). Lightdutv (L series) stud ends with type E sealing in accordance with this part of IS0 9974 may be used at working pressures up to 25 MPa (250 bar). The permissible working pressure depends upon the stud end size, materials, design, working conditions, application, etc.

For threaded prots and stud ends specified in new designs in hydraulic fluid power application, only ISO 6149 is to be used. Threaded prots 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.

Conformance to the dimentional information in this part of ISO 9974 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in this part of ISO 9974 to assure that components comply with the performance ratings.
