IEC 61000-6-4:2018 is also available as IEC 61000-6-4:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
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.

CISPR/TR 31:2012 covers the rationale behind the actual database covering the characteristics of radio services. The objective of the database is to register those characteristics which are relevant for derivation and specification of limits for disturbance emissions from electric and/or electronic equipment, systems and installations. Committees responsible for generic and/or product emission EMC standards should use this information together with CISPR 23. This second edition includes the replacement of CISPR 23 as reference standard for the determination of limits by CISPR 16-4-4:2007 on "model for the calculation of limits for the protection of radio services".

IEC 61000-6-3:2006+A1:2010 This part of IEC 61000 for EMC emission requirements applies to electrical and electronic apparatus intended for use in residential, commercial and light-industrial environments. Emission requirements in the frequency range 0 Hz to 400 GHz are covered. No measurement needs to be performed at frequencies where no requirement is specified. This generic EMC emission standard is applicable if no relevant dedicated product or product-family EMC emission standard exists. This standard applies to apparatus intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source, which is intended to interface between the apparatus and the low-voltage public mains network. This standard applies also to apparatus which is battery operated or is powered by a non-public, but non-industrial, low-voltage power distribution system if this apparatus is intended to be used in the locations described below. The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations that are included:
- residential properties, for example houses, apartments;
- retail outlets, for example shops, supermarkets;
- business premises, for example offices, banks;
- areas of public entertainment, for example cinemas, public bars, dance halls;
- outdoor locations, for example petrol stations, car parks, amusement and sports centres;
- light-industrial locations, for example workshops, laboratories, service centres.
Locations that are characterised by being supplied directly at low voltage from the public mains network are considered to be residential, commercial or light-industrial. The object of this standard is to define the emission test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances. The emission requirements have been selected so as to ensure that disturbances generated by apparatus operating normally in residential, commercial and light-industrial locations do not exceed a level which could prevent other apparatus from operating as intended. Fault conditions of apparatus are not taken into account. Not all disturbance phenomena have been included for testing purposes in this standard but only those considered as relevant for the equipment covered by this standard. These requirements represent essential electromagnetic compatibility emission requirements. Requirements are specified for each port considered. This consolidated version consists of the second edition (2006) and its amendment 1 (2010). Therefore, no need to order amendment in addition to this publication.

CISPR 16-2-5:2008(E) deals with in situ electromagnetic disturbance measurements in any environment from physically large equipment and systems excluding networks. It covers both radiated and conducted emission phenomena, and does not deal with immunity tests. This technical report is intended to be applied primarily to such physically large equipment which are not under the scope of any existing emission standards (as for example CISPR 11 and CISPR 22). It serves only as a guideline on how to deal with emissions of that equipment at the particular location of installation. It does not establish any emission requirements. Due to the severe impact of the conditions existing at a particular location of operation and the use of the respective large equipment, however, it is not intended to use the measurements in the frame of type testing. Reference in-situ measurement distances will be given. This allows comparison of the measurement results with limits from existing relevant standards. The frequency range under consideration is from 9 kHz to 18 GHz.
