IEC 62037-5:20 21作为IEC 62037-5:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62037-5:20 21定义了测试装置和推荐用于测量通常用于无线通信系统的滤波器产生的无源互调电平的程序。目的是定义低互调（低IM）应用中使用的滤波器的鉴定和验收测试方法。这第二版取消并取代了2013年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a.更新了动态测试要求，以定义冲击能量和对受试器械施加冲击的位置。

IEC 62037-5:2021 is available as IEC 62037-5:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62037-5:2021 defines test fixtures and procedures recommended for measuring levels of passive intermodulation generated by filters, typically used in wireless communication systems. The purpose is to define qualification and acceptance test methods for filters for use in low intermodulation (low IM) applications. This second edition cancels and replaces the first edition published in 2013. This edition includes the following significant technical changes with respect to the previous edition:
a. dynamic testing requirements updated to define impact energy and locations to apply impacts to devices under test.
