测量、控制和实验室用电气设备——EMC要求–；第3-1部分:安全相关系统和拟执行安全相关功能的设备的抗扰度要求（功能安全）–；一般工业应用

[中文适用范围]： 本部分 IEC 61326 涵盖 IEC 61326-1 范围内的所有设备，但仅限于工业应用中执行 IEC 61508 中定义的 SIL 1-3 安全功能的系统和设备。本产品系列标准涵盖的电磁环境为工业环境，包括室内和室外，如 IEC 61000-6-2 中描述的工业场所或 IEC 61326-1 中 3.8 定义的场所。本文件排除了用于其他电磁环境的设备和系统，例如过程工业或具有潜在爆炸性环境的场所。根据 IEC 61508 或 IEC 61511 被视为“已证明使用”或“先前使用”的设备和系统不在本文件范围内。用于建筑物保护的火灾报警系统和安全报警系统不在本文件范围内。 [外文原描述]： IEC 61326-3-1:2017 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 61326-3-1:2017 covers all equipment within the scope of IEC 61326-1, but is limited to systems and equipment for industrial applications 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 Table 8 - Frequency ranges of mobile transmitters and ISM equipment, - updating Figure A.1 and Figure 1 for better readability.
