标准摘要
[中文适用范围]： IEC 61326 的这一部分涵盖了 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 中 SIL 1-3 定义的安全功能。本产品系列标准涵盖的电磁环境为工业@室内和室外@，并基于流程工业@的要求，特别是化学/石化/制药制造厂，采用附录 C 中给出的缓解措施。电磁环境之间的差异本文件所涵盖的与一般工业环境（参见 IEC 61326-3-1）相比，是由于针对电磁现象采取的缓解措施导致了特定的电磁环境，其测试值已在实践中得到验证。具有特定电磁环境的工业应用环境通常包括以下特征： 进入受限的工业区域；移动发射机的有限使用；电源和控制@信号或通讯线专用电缆；电源和控制信号或通信电缆之间的分离；厂房主要由金属结构组成；通过适当的措施进行过电压/雷击保护（例如@建筑物的金属结构或使用保护装置）；交流主电源驱动的管道加热系统；敏感区域附近无高压变电站；存在仅使用低功率 ISM 频率的 CISPR 11 第 2 组 ISM 设备；有能力的员工；设备和系统的定期维护；设备和系统的装配和安装指南。设备和系统被视为“经过使用验证”根据 IEC 61508 或“优先使用”根据 IEC 61511 的规定不包括在本文件的范围内。用于保护建筑物的火灾报警系统和安全报警系统不包括在本文件的范围内。 [外文原描述]： 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.
