IEC 61326-3-2:20 17 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 61326-3-2:20 17涵盖IEC 61326-1范围内的所有设备，但仅限于特定电磁环境内的工业应用系统和设备，旨在执行IEC 61508和SIL 1-3中定义的安全功能。 这第二版取消并取代了2008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:-根据IEC 61000-4-3将射频电磁场测试的频率范围扩展至6GHz， -根据通用标准IEC 61000-6-7用DS替换性能标准FS， -增加表1-在应用性能标准DS期间要考虑的方面， -包括根据IEC 61000-4-34对电流消耗>16 A的器件进行抗扰度测试， -更新图A.1和图1以提高可读性， -增加根据IEC 61000-4-16的测试，以取代根据IEC 61000-4-6在10kHz和150kHz之间的频率范围内的测试。

IEC 61326-3-2:2017 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 61326-3-2:2017 covers all equipment within the scope of IEC 61326-1, but is limited to systems and equipment for industrial applications within a specified electromagnetic environment and intended to perform safety functions as defined in IEC 61508 with SIL 1-3.
This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- extension of the frequency range up to 6 GHz for the radio-frequency electromagnetic field test according to IEC 61000-4-3,
- replacement of the performance criterion FS with DS according to the generic standard IEC 61000-6-7,
- adding Table 1 - Aspects to be considered during application of performance criterion DS,
- including immunity tests for devices with current consumption > 16 A according to IEC 61000-4-34,
- updating Figure A.1 and Figure 1 for better readability,
- adding tests according to IEC 61000-4-16 to replace the tests according to IEC 61000-4-6 in the frequency range between 10 kHz and 150 kHz.
