IEC 61000-6-3:20 20是通用EMC排放标准，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3.1.14）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涵盖住宅、商业和轻工业环境中使用的所有设备。如果有任何疑问，适用IEC 61000-6-3中的要求。在高达400 GHz的频率范围内的传导和辐射发射要求被认为是必不可少的，并已被选择为在规定的电磁环境中提供足够的无线电接收保护。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。本文件中的发射要求不适用于ITU定义的无线电发射机的有意发射及其谐波。本第三版取消并取代了2006年出版的第二版及其修正案1:20 10。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)用于测量DC端口上的传导发射的替代方法； b)仅适用于拟用于住宅场所的设备的限制和要求； c)对DC电源端口的更严格限制。注1本文件不涉及安全性考虑。 注2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3设备故障状态下产生的扰动不在本文件范围内。 注4由于本文件中的要求比IEC 61000-6-4和IEC 61000-6-8中的要求更严格或等同，满足本文件要求的设备符合IEC 61000-6-4和IEC 61000-6-8的要求。

IEC 61000-6-3:2020 is a generic EMC emission standard 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 3.1.14) 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 environments 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. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. 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 emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU. This third edition cancels and replaces the second edition published in 2006 and its Amendment 1:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) alternative method for measuring conducted emissions on DC ports;
b) limits and requirements applicable only to equipment intended to be used in residential locations;
c) more stringent limits for DC power ports.
NOTE 1 Safety considerations are not covered by this document.
NOTE 2 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 3 Disturbances generated in fault conditions of equipment are not covered by this document.
NOTE 4 As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.
