测量、控制和实验室用电气设备电磁兼容性要求第3-2部分:安全相关系统和执行安全相关功能（功能安全）设备的抗扰度要求具有规定电磁环境的工业应用

[中文适用范围]： 本部分IEC 61326涵盖了IEC 61326-1范围内的所有设备，但仅限于工业应用中执行IEC 61508定义的SIL 1-3安全功能的系统和设备。电磁环境包括工业和室内外环境，具有特定特性（例如过程工业）和基于过程工业要求的化工/石化/制药制造工厂，使用附录C中给出的缓解措施。与一般工业环境（参见IEC 61326-3-1）相比，本文件涵盖的电磁环境的差异在于采用了针对电磁现象的缓解措施，导致具有实践中证明的测试值的特定电磁环境。工业应用的典型环境特征包括：限制访问的工业区域、限制使用移动发射器、专用电源和控制电缆、信号或通信线路、电源与控制、信号或通信电缆之间的分离、主要由金属结构组成的工厂建筑、通过适当措施（例如建筑物的金属结构或使用保护装置）进行过电压/雷电保护、可能存在由交流主电源驱动的管道加热系统、敏感区域附近没有高压变电站、存在仅使用低功率ISM频率的CISPR 11 Group 2 ISM设备、合格人员、设备和系统的定期维护、设备和系统的安装指南。根据IEC 61508或IEC 61511的“经过验证使用”或“先前使用”的设备和系统不在本文件范围内。 [外文原描述]： IEC 61326-3-2:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version 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 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.
