IEC 60512-9-5:20 20 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60512-9-5:20 20当详细产品规范要求时，用于测试技术委员会48范围内的连接器或无焊连接。如果在详细产品说明书中有规定，也可用于类似器械。本文件的目的是详细说明通过循环电流负载使无焊连接经受热应力调节的标准方法。第二版取消并取代了2010年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -增加了方法B，并将以前的测试方法更名为方法A，为具有较大热质量的产品提供更可调时间“开启”和“关闭”的替代方法。 -增加了引言，以提供本次修订的背景。

IEC 60512-9-5:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60512-9-5:2020 when required by the detail product specification, is used for testing connectors or solderless connections within the scope of technical committee 48. It may also be used for similar devices when specified in a detail product specification. The object of this document is to detail a standard method for subjecting solderless connections to thermal stress conditioning by cyclic current loading. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- added method B and renamed the former test method as method A, to provide an alternative with more adjustable time “ON” and “OFF” for products with larger thermal mass.
- added introduction to provide background of this revision.
