SAE J1502规定了带有公制M14x1.5或英制9/16-18直螺纹螺柱端的诊断连接器阳半部分的尺寸、性能要求和测试程序。联轴器设计用于矿物基液压油。它用于SAE J1116中规定的机器。它不适用于不在机器上的配套液压快速接头。可在42 MPa的工作压力下使用符合SAE J1502的诊断接头。允许工作压力取决于材料、设计、工作条件、应用等。符合SAE J1502本部分中的尺寸信息并不保证额定性能。各制造商应根据本文件中的规范进行测试，以确保部件符合性能等级。

SAE J1502 specifies dimensions, performance requirements, and test procedures for the male half of a diagnostic coupler with either a metric M14x1.5 or an inch 9/16-18 straight thread stud end. The coupler is designed for use with a mineral-based hydraulic fluid. It is used on machines specified in SAE J1116. It does not apply to the mating hydraulic quick action couplings not on the machine.Diagnostic couplings in accordance with SAE J1502 may be used at a working pressure of 42 MPa. The permissible working pressure depends upon the materials, design, working conditions, application, etc.Conformance to the dimensional information in this part of SAE J1502 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in this document to ensure that components comply with the performance rating.
