标准摘要
[中文适用范围]： 本文件规定了用于1S60 9974-1端口的公制外六角和内六角孔用端口插头的尺寸和性能要求。符合本文文件规定的端口插头可用于最高工作压力为63 MPa [630 bar]的工作环境中，允许的最大工作压力取决于插头的端部尺寸、材料、设计、工作条件、应用等。仅符合本文件中的尺寸信息并不保证额定性能 [外文原描述]： ISO 9974-4:2016 specifies dimensions and performance requirements for metric external hex and internal hex port plugs for use with ISO 9974‑1 ports. Port plugs in accordance with this document can be used at working pressures up to 63 MPa [630 bar[1]]. The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this document does not guarantee rated performance. NOTE The Introduction of this document gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications. [1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
