IEC 61000-6-3:20 26仅适用于尚未发布相关专用产品或产品系列EMC排放标准的情况。IEC 61000排放要求的这一部分适用于住宅（见3.1.21）场所使用的电气和电子设备。IEC 61000的这一部分也适用于预期在不属于IEC 61000-6-8或IEC 61000-6-4范围的其他位置使用的电气和电子设备。IEC 61000-6-3或IEC 61000-6-8涵盖了住宅、商业和轻工业场所使用的所有设备。如果有任何疑问，适用IEC 61000-6-3中的要求。具有无线电功能（3.1.20）的设备包括在本文件的范围内。然而，本文件中的发射要求并不适用于这些无线电发射机的有意发射、其谐波和带外发射。出于测试目的，并非所有干扰现象都包括在内，而仅包括那些被认为与打算在本文件所包括的位置内运行的设备相关的干扰现象。 本文件的目标是: -制定要求，为9千赫至400千兆赫频率范围内的无线电接收提供足够水平的保护； -制定要求，对本文件范围内的设备发出的传导和辐射电磁干扰提供足够水平的保护； -支持测量的再现性和结果的重复性。 注1？在特殊情况下，会出现本文件中规定的水平无法提供足够保护的情况；例如，在靠近设备使用敏感接收器的情况下。在这些情况下，可以采用特殊的缓解措施。 注2？设备故障条件下产生的干扰不在本文件范围内。 注3？本文件中的要求比IEC 61000-6-4和IEC 61000-6-8中规定的要求更严格或相当。 这第四版取消并取代了2020年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)增加了磁场发射要求，包括WPT函数的测量； b)低压交流电源要求的扩展，以覆盖9千赫至150千赫的范围； c)范围内增加了具有无线电功能的产品； d)增加了机架安装设备的FAR限制。

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.
