电磁兼容 (EMC) - 第 6-3 部分：通用标准 - 住宅环境设备的发射标准

[中文适用范围]： IEC 61000-6-3:2026 包含官方国际标准的正式文本及其修订对照版本。修订对照版仅提供英文版，便于快速、便捷地对照官方标准与其上一版本之间的所有变更。IEC 61000-6-3:2026 仅在尚未发布相关的专用产品或产品族电磁兼容性发射标准时适用。 本部分 IEC 61000 标准适用于拟在居民场所（见条款 3.1.21）使用的电气设备与电子产品；同时也适用于拟在其他场所使用的电气电子产品，且这些场所不属于 IEC 61000-6-8 或 IEC 61000-6-4 的适用范围。总体目标是，凡用于居民、商业及轻工业场所的所有设备，均应纳入 IEC 61000-6-3 或 IEC 61000-6-8 的适用范围。如有任何疑虑，则应适用 IEC 61000-6-3 中的要求。 具有射频功能的设备（见条款 3.1.20）属于本文件范围，但其中所规定的发射要求不适用于此类发射设备的有意发射、其谐波及带外发射。 就测试目的而言，并非所有干扰现象均已纳入测试范围，仅包括与本文件所述适用场所内运行设备相关的干扰现象。 本文件的目标包括： - 建立要求，确保在 9 kHz 至 400 GHz 频率范围内对无线电接收提供充分保护； - 建立要求，确保对本文件范围内设备产生的传导及辐射电磁干扰提供充分保护； - 支持测量可复现性及结果可重复性。 注 1：在特殊情况下，可能出现本文件所规定水平不足以提供充分保护的情形；例如，敏感接收设备紧邻某台设备运行。此时可采取专门的缓解措施。 注 2：设备在故障条件下产生的干扰不在本文件范围内。 注 3：本文件中的要求严于或与 IEC 61000-6-4 和 IEC 61000-6-8 中的要求等同。 本第四版替代并取消 2020 年发布的第三版，构成一次技术性修订。与上一版本相比，本版本包含以下重大技术变更： a) 增加磁场发射要求，包括对无线电能传输（WPT）功能的测量要求； b) 将低压交流电源相关要求扩展至覆盖 9 kHz 至 150 kHz 频率范围； c) 将具有射频功能的產品纳入适用范围； d) 为机架安装设备增加了机架天线场强（FAR）限值。 [外文原描述]： IEC 61000-6-3:2026 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 61000-6-3:2026 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.
