DIN EN ISO 1179-4-2008 通用和液压传动用连接件.带弹性体密封或金属对金属密封的ISO 228-1螺纹的孔口和螺柱端.第4部分:仅与金属对金属密封(B型)的通用螺柱端
Connections for general use and fluid power - Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing - Part 4: Stud ends for general use only with metal-to-metal sealing (type B) (ISO 1179-4:2007); German version EN ISO 1179
This part of ISO 1179 specifies dimensions, performance requirements and test procedures for stud ends with
ISO 228-1 threads and metal-to-metal sealing for general use only. These stud ends should not be used for
leak-free hydraulic fluid power applications.
Stud ends in accordance with this part of ISO 1179 may be used at working pressures up to 40 MPa (400 bar)
for the S series, up to 25 MPa (250 bar) for the L series, and up to 10 MPa (100 bar) for the LL series. 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.
Each manufacturer shall perform tests 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 and ISO 8434-2.
NOTE 2 The introduction of this part of ISO 1179 gives recommendations for ports and stud ends to be used for new
designs in hydraulic and pneumatic fluid power applications.
