标准摘要
[中文适用范围]： 本文件规定了与 ISO 6149-1 端口一起使用的外六角和内六角端口插头的尺寸和性能要求。 根据本文件的端口塞可在高达 63 MPa (630 bar1)) 的工作压力下使用。 允许的工作压力取决于塞端尺寸、材料、设计、工作条件、应用等。 符合本文件中的尺寸信息并不能保证额定性能。 每个制造商都应根据本文件中包含的规范进行测试，以确保组件符合性能等级。 警告 — 使用符合本文件的螺柱端部以及符合 ISO 1179、ISO 9974 和 ISO 11926 相关部分的端口可能会导致危险情况。 [外文原描述]： ISO 6149-4:2017 specifies dimensions and performance requirements for external hex and internal hex port plugs for use with ISO 6149‑1 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. Each manufacturer is expected to perform testing according to the specification contained in this document to assure that components comply with the performance ratings. WARNING: The use of stud ends conforming to this document with ports conforming to the relevant parts of ISO 1179, ISO 9974 and ISO 11926 could lead to a hazardous situation. [1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
