发布日期： 2022-11-10

本文件规定了带螺纹的重型（S系列）和轻型（L系列）螺柱端部的尺寸、性能要求和测试程序，以及ISO 228-1中规定的与之配套使用的弹性密封（E型）。
重型（S？系列）螺柱端头类型根据本文件的E密封可在63？的工作压力下使用MPa（630巴）。轻型（L？系列）螺柱端头类型根据本文件的E密封可在25？的工作压力下使用MPa（250巴）。
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ISO8434-1，ISO8434-2和ISO8434-6.
注意本简介为液压和气动流体动力应用中的新设计提供了端口和螺柱端的建议。

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.
