IEC 60512-9-4:20 11当详细规范要求时，用于测试IEC技术委员会48范围内的连接器。当在详细说明书中指定时，它也可以用于类似的设备。本标准的目的是详细说明一种标准测试方法，以评估连接器在维护过程中承受触点重复拔出和插入引起的应力的能力。本标准取消并取代1992年发布的IEC 60512-5的试验9d，构成技术修订。 本出版物应与IEC 60512-1:20 01和IEC 60512-1-100:2006一起阅读。

IEC 60512-9-4:2011 when required by the detail specification, is used for testing connectors within the scope of IEC technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this standard is to detail a standard test method to assess the ability of a connector to withstand stresses caused by repeated extraction and insertion of contacts during maintenance. This standard cancels and replaces Test 9d of IEC 60512-5, issued in 1992, and constitutes a technical revision.

This publication is to be read in conjunction with IEC 60512-1:2001 and IEC 60512-1-100:2006.
