电磁兼容性 (EMC) 第 4-6 部分：测试和测量技术 对射频场引起的传导干扰的抗扰度

[中文适用范围]： IEC 61000-4-6:2023 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 61000-4-6: 2023 涉及电气和电子设备对来自频率范围 150 kHz 至 80 MHz 的射频 (RF) 发射器的电磁干扰的传导抗扰度要求。注 1：产品委员会可能决定将本文件中描述的方法也用于高达 230 MHz 的频率（参见附件 B），尽管这些方法和测试仪器旨在用于高达 80 MHz 的频率范围。不具有至少一根能够将设备耦合到干扰射频场的导线或电缆（例如电源、信号线或接地连接）的设备被排除在本文件的范围之外。注 2：IEC 61000 本部分规定了测试方法，用于评估电磁辐射引起的传导干扰信号对相关设备的影响。这些传导干扰的模拟和测量对于定量确定影响来说不够精确。指定的测试方法的主要目标是在各种设施中建立足够的结果重复性，以进行效果的定量分析。本文件的目的是建立一个通用参考，用于评估电气和电子设备在受到射频场引起的传导骚扰时的功能抗扰度。本文件中的测试方法描述了评估设备或系统对特定现象的抗扰度的一致方法。注 3：如 IEC 指南 107 中所述，本文件是供 IEC 产品委员会使用的基本 EMC 出版物。正如指南 107 中所述，IEC 产品委员会负责确定是否应应用此抗扰度测试标准，如果应用，他们负责确定适当的测试级别和性能标准。本第五版取消并取代了 2013 年发布的第四版。本版本构成技术修订。该版本相对于前一版本包括以下重大技术变化： a) 修改了注射装置的选择； b) 取消了钳位注入的 AE 阻抗检查的需要，并删除了附录 H； c) 修订饱和度检查； d) 关于多信号测试的新附录 H； e) 仅使用反馈回路进行电平设置。 [外文原描述]： IEC 61000-4-6:2023 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 61000-4-6: 2023 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. NOTE 1 Product committees might decide to use the methods described in this document also for frequencies up to 230 MHz (see Annex B) although the methods and test instrumentation are intended to be used in the frequency range up to 80 MHz. Equipment not having at least one conducting wire or cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF fields is excluded from the scope of this document. NOTE 2 Test methods are specified in this part of IEC 61000 to assess the effect that conducted disturbing signals, induced by electromagnetic radiation, have on the equipment concerned. The simulation and measurement of these conducted disturbances are not adequately exact for the quantitative determination of effects. The test methods specified are structured for the primary objective of establishing adequate repeatability of results at various facilities for quantitative analysis of effects. The object of this document is to establish a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF fields. The test method in this document describes a consistent method to assess the immunity of an equipment or system against a specified phenomenon. NOTE 3 As described in IEC Guide 107, this document is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. This fifth edition cancels and replaces the fourth edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) selection of injection devices revised; b) need of AE impedance check for clamp injection removed and Annex H deleted; c) saturation check revised; d) new Annex H on testing with multiple signals; e) level-setting only with feedback loop.
