新的！IEC 61326-3-2:20 17作为IEC 61326-3-2:20 17 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 61326-3-2:20 17涵盖IEC 61326-1范围内的所有设备，但仅限于指定电磁环境内工业应用的系统和设备，并旨在执行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将射频电磁场测试的频率范围扩展至6 GHz-4-3, -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。

NEW!IEC 61326-3-2:2017 is available as IEC 61326-3-2:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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.
