Omfang

This part of IS0 9974 specifies dimensions, performance requirements and test procedures for heavy-duty (S series) and light-duty (L series) stud ends with IS0 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)). Lightduty (L series) stud ends with type E sealing in accor- dance with this part of IS0 9974 may be used at working pressures up to 25 MPa (250 bar). The permiss- ible working pressure depends upon the stud end size, materials, design, working conditions, application, etc. For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, only IS0 6149 is to be used. Threaded ports and stud ends in accordance with IS0 1179, IS0 9974 and IS0 11926 are not to be used for new designs in hydraulic fluid power applications. Conformance to the dimensional information in this part of IS0 9974 does not guarantee rated perform- ance. Each manufacturer should perform testing according to the specification contained in this part of IS0 9974 to assure that components comply with the performance ratings.
