IEC 61000-6-8:20 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商业和轻工业（见3.1.3）场所的电气和电子设备。本文件适用于满足以下使用限制的设备: 定义为专业设备（见3.1.13）， 由专业人员安装和维护（见3.1.14和第6条）， 不适用于居住场所（见3.1.16）。 IEC 61000-6-3适用于不满足这些限制的用于商业和轻工业场所的电气和电子设备。目的是所有用于住宅、商业和照明的设备-IEC 61000-6-3或IEC 61000-6-8涵盖了工业环境。如果有任何疑问，则适用IEC 61000-6-3中的要求。涵盖0 Hz至400 GHz频率范围内的发射要求。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。注1？本文件不涉及安全性问题。 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，采用特殊的缓解措施来减少任何影响。 注3？设备故障条件下产生的干扰不在本文件范围内。 注4？符合IEC 61000-6-3的设备适用于这些规定的位置。

IEC 61000-6-8: 2020 is a generic EMC emission standard and 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 in commercial and light-industrial (see 3.1.3) locations. This document applies to equipment that satisfy the following restrictions of use:

• is defined as professional equipment (see 3.1.13),
• is professionally installed and maintained (see 3.1.14 and Clause 6),
• is not intended to be used in residential locations (see 3.1.16).

IEC 61000-6-3 applies to electrical and electronic equipment intended for use at commercial and light-industrial locations that do not satisfy these restrictions. 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. Emission requirements within the frequency range 0 Hz to 400 GHz are covered. 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.
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, employ special mitigation measures to reduce any impact.
NOTE 3？Disturbances generated in fault conditions of equipment are not covered by this document.
NOTE 4？Equipment which complies with IEC 61000-6-3 are suitable for use within these defined locations.
