IEC 61000-6-4:20 18 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 61000-6-4:20 18排放要求适用于工业环境中使用的电气和电子设备（参见3。1.12)位置。本文件不适用于IEC 61000-6-3范围内的设备。本文件涵盖的环境涵盖室内和室外位置。本文件涵盖了频率范围9 kHz至400 GHz的发射要求，并已被选择为在规定的电磁环境中提供足够水平的无线电接收保护。在没有规定要求的频率下，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必要条件。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预期在本文件所包括的环境中运行的设备相关的干扰现象。为所考虑的每个端口指定了要求。本通用EMC排放标准适用于没有适用产品或产品系列EMC排放标准的情况。？本第三版取消并取代了2006年出版的第二版和修正案1:20 10本版本构成技术修订。与上一版相比，此版本包括以下重大技术变更: a)未来可能对DC端口的要求； b)FAR内可能的未来辐射极性比发射极限； c)定义哪个平均检测器用于频率高于1GHz的发射测量，以及使用峰值检测器的结果对于所有测量都是可接受的； d)不同EUT测试安排的定义。 关键词:工业环境排放标准

IEC 61000-6-4:2018 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

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.
