标准摘要
[中文适用范围]： 本文件规定了带螺纹的重型（S 系列）和轻型（L 系列）螺柱端头以及与它们一起使用的弹性密封件（E 型）的尺寸、性能要求和测试程序，如ISO 228-1。 根据本文件采用 E 型密封的重型（S 系列）螺柱端头可在高达 63 MPa (630 bar) 的工作压力下使用。 根据本文件采用 E 型密封的轻型（L 系列）螺柱端头可在高达 25 MPa (250 bar) 的工作压力下使用。 允许的工作压力取决于尺寸、材料、设计、工作条件、应用等。 本文件适用于 ISO 8434-1、ISO 8434-2 和 ISO 8434-6 中详述的连接器。 注：简介中给出了端口和连接器的建议。 螺柱端用于液压和气动流体动力应用的新设计。 [外文原描述]： This document specifies the dimensions, performance requirements and test procedures for heavy-duty (S series) and light-duty (L series) stud ends with threads, and the elastomeric sealing (type E) that is used with them as defined in ISO 228-1. Heavy-duty (S series) stud ends with type E sealing in accordance with this document can be used at working pressures up to 63 MPa (630 bar). Light-duty (L series) stud ends with type E sealing in accordance with this document can be used at working pressures up to 25 MPa (250 bar). The permissible working pressure depends upon size, materials, design, working conditions, application, etc. This document is applicable to connectors detailed in ISO 8434-1, ISO 8434-2 and ISO 8434-6. NOTE The Introduction gives recommendations for ports and stud ends to be used for new designs in hydraulic and pneumatic fluid power applications.
