电磁兼容性（EMC）第6-4部分:通用标准工业环境发射标准

[中文适用范围]： 本部分IEC 61000关于发射要求适用于工业环境中使用的电气和电子设备（见3.1.12）。 本文件不适用于IEC 61000-6-3范围内的设备。 本文件涵盖的环境包括室内和室外场所。 本文件涵盖了9 kHz至400 GHz频率范围内的发射要求，并已选择在定义的电磁环境中为无线电接收提供足够的保护水平。在未指定要求的频率下不需要进行测量。这些要求被认为是为无线电服务提供足够保护水平的关键。 并非所有干扰现象都包括在测试目的中，只有那些被认为与设备在本文档包括的环境中运行相关的现象。 为每个考虑的端口指定了要求。 在无适用的产品或产品系列EMC发射标准可用时，应使用此通用EMC发射标准。 注1：安全考虑不在本文件范围内。 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，当敏感接收器在靠近设备的地方使用时。在这些情况下，可能需要采用特殊的缓解措施。 注3：本文件不包括设备故障条件下产生的干扰。 [外文原描述]： IEC 61000-6-4:2018 for emission requirements applies to electrical and electronic equipment intended for use within the environment existing at industrial (see 3.1.12) locations. This document does not apply to equipment that fall within the scope of IEC 61000-6-3. The environments encompassed by this document cover both indoor and outdoor locations. Emission requirements in the frequency range 9 kHz to 400 GHz are covered in this document and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. No measurement needs to be performed at frequencies where no requirement is specified. These requirements are considered essential to provide an adequate level of protection to radio services. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the environments included within this document. Requirements are specified for each port considered. This generic EMC emission standard is to be used where no applicable product or product-family EMC emission standard is available. This third edition cancels and replaces the second edition published in 2006 and Amendment 1:2010 This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) possible future requirements on DC ports; b) possible future radiated polarity specific emission limits within a FAR; c) the definition of which average detector is used for emission measurements at frequencies above 1GHz and that results using a peak detector are acceptable for all measurements; d) the definition of different EUT test arrangements.
