BS EN ISO 9974-1:2000
This standard BS EN ISO 9974-1:2000 Connections for general use and fluid power. Ports and stud ends with ISO 261 threads with elastomeric or metal-to-metal sealing is classified in these ICS categories:
- 23.100.40 Piping and couplings
- 23.100.60 Filters, seals and contamination of fluids
This part of ISO 9974 specifies dimensions for ports with ISO 261 threads and elastomeric (type E) or metal-tometal (type 8) sealing for general use and in fluid power applications with the stud ends detailed in ISO 9974-2 and ISO 9974-3. It also specifies test methods and the designation of these ports.
Ports in accordance with this part of ISO 9974 may be used at working pressures up to 63 MPa (630 bar l)). 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.
