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.
IEC 61000-6-3:2020(ed3.0)和IEC 61000-6-8:2020在2020年7月30日发布。
IEC 61000-6-3:2020 电磁兼容性（EMC）第6-3部分：通用标准 居住, 商业和轻工业环境设备的发射标准，是通用的电磁兼容发射标准，适用于尚未发布相关的专用产品或产品系列的EMC发射标准的产品。IEC 61000中关于发射要求的这一部分适用于拟在住宅区使用的电气和电子设备。IEC 61000的这一部分也适用于不属于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。其目的是使住宅、商业和轻工业环境中使用的所有设备符合IEC 61000-6-3或IEC 61000-6-8的要求。频率范围在400GHz以内的传导和发射要求被认为是必要的，但只有被认定在本文件所含位置内运行的设备有关的干扰现象被包含在测试中。本文件中的发射要求并不适用于来自ITU定义的无线电发射机的有意发射及其谐波。
IEC 61000-6-3:2020为技术修订版,取代IEC 61000-6-3:2006+AMD1:2010。
与前一版本相比，本版本包括以下重大技术更改：
a） 测量直流端口传导发射的替代方法；
b） 适用于拟在住宅区使用的设备的限制和要求；
c） 直流电源端口的限制更严格。
而IEC 61000-6-8:2020电磁兼容性（EMC）-第6-8部分：通用标准 商用和轻工业场所专业设备的发射标准, 是通用的EMC发射标准，适用于在没有发布相关的专用产品或产品系列EMC发射标准的拟用于商业和轻工业场所的电气和电子设备。适用设备：被定义为专业设备、专业安装和维护、不用于住宅区。
制造商可以开始按照标准IEC 61000-6-3:2020和IEC 61000-6-8:2020测试其产品。
