电磁兼容性（EMC） 第6-3部分：通用标准 居民区设备的发射标准

[中文适用范围]： IEC 61000-6-3:2026 仅在没有适用的专用产品或产品族电磁兼容（EMC）发射标准时适用。本部分 IEC 61000 关于发射限值的规定，适用于拟在居民区（见 3.1.21）使用的电气和电子设备；同时也适用于拟在居民区之外、但不属于 IEC 61000-6-8 或 IEC 61000-6-4 适用范围内的场所使用的电气和电子设备。其总体目标是：所有在居民区、商业区及轻工业场所使用的设备，均应由 IEC 61000-6-3 或 IEC 61000-6-8 覆盖；如有任何疑问，则应适用 IEC 61000-6-3 的要求。具有无线电功能的设备（见 3.1.20）亦属于本文件适用范围，但本文件中的发射要求不适用于此类无线电发射器的有意发射、其谐波及其带外发射。 为进行试验而涉及的干扰现象并非全部包含，仅包括与本文件所涵盖场所内设备运行相关的、被认定为必要的干扰现象。本文件的目标是： - 建立要求，确保在 9 kHz 至 400 GHz 频段内对无线电接收提供充分的保护； - 建立要求，确保对本文件适用范围内设备产生的传导和辐射电磁干扰提供充分的防护； - 支持测量结果的可复现性与可重复性。 注 1：在特殊情况下，可能出现本文件规定的限值不足以提供充分保护的情形，例如敏感接收器与某设备近距离毗邻布置。此类情况下可采取专门的抑制措施。 注 2：设备在故障条件下产生的干扰不在本文件覆盖范围内。 注 3：本文件的要求比或等同于 IEC 61000-6-4 和 IEC 61000-6-8 中规定的要求更为严格或等效。 第四版取消并替代 2020 年发布的第三版，构成技术性修订。本次修订与上一版相比包含以下重要技术变更： a) 增加磁场发射要求，包括无线电力传输（WPT）功能的测量； b) 将低压交流 mains 电源的发射限值适用范围扩展至 9 kHz 至 150 kHz； c) 将具有无线电功能的产品纳入适用范围； d) 增加机架式设备在 FAR（自由空气范围）下的限值要求。 [外文原描述]： IEC 61000-6-3:2026 is applicable only if no relevant dedicated product or product family EMC emission standard has been published. This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.21) locations. This part of IEC 61000 also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4. The intention is that all equipment used in the residential, commercial and light-industrial locations are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. Equipment that has a radio function (3.1.20) are included in the scope of this document. However, the emission requirements in this document are not intended to be applicable to the intentional transmissions from these radio transmitters, their harmonics and their out of band emissions. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document. The objectives of this document are: - to establish requirements that provide an adequate level of protection of radio reception in the frequency range 9 kHz to 400 GHz; - to establish requirements that provide an adequate level of protection against conducted and radiated electromagnetic disturbances emitted by equipment in the scope of this document; - to support the reproducibility of measurement and the repeatability of results. NOTE 1 In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example, where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures can be employed. NOTE 2 Disturbances generated in fault conditions of equipment are not covered by this document. NOTE 3 The requirements in this document are more stringent or equivalent to the requirements specified in IEC 61000-6-4 and IEC 61000-6-8. This fourth edition cancels and replaces the third edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the addition of magnetic field emission requirements, including the measurement of WPT function; b) the extension of low-voltage AC mains power requirements to cover the range 9 kHz to 150 kHz; c) products with a radio function have been added to the scope; d) limits in a FAR for rack mounted equipment have been added.
