Electromagnetic compatibility (EMC) - Part 6-8: Generic standards - Emission standard for professional equipment in commercial and light-industrial locations

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.

IEC 61000-6-8: 2020 est une norme d'émissions CEM générique et n'est applicable que si aucune norme d'émissions CEM de produit ou de famille de produits dédiée n'a été publiée. La présente partie de l’IEC 61000 concernant les exigences d’émission s'applique aux matériels électriques et électroniques destinés à être utilisés dans des environnements commerciaux et de l'industrie légère (voir 3.1.3). Le présent document s’applique aux matériels qui satisfont aux restrictions d’utilisation suivantes:

   
• qui sont définis comme matériels professionnels (voir 3.1.13),

   
• qui sont installés et maintenus par des professionnels (voir 3.1.14 et Article 6),

   
• qui ne sont pas destinés à être utilisés dans des environnements résidentiels (voir 3.1.16).

L‘IEC 61000-6-3 s’applique aux matériels électriques et électroniques destinés à être utilisés dans des environnements commerciaux et de l'industrie légère qui ne satisfont pas à ces restrictions.
L’objectif est que tous les matériels utilisés dans les environnements résidentiels, commerciaux et de l’industrie légère soient couverts par l’IEC 61000-6-3 ou l’IEC 61000-6-8. En cas de doute, les exigences spécifiées dans l’IEC 61000-6-3 s'appliquent. Les exigences d’émission dans la plage de fréquences de 0 Hz à 400 GHz sont couvertes. Les exigences d’émissions conduites et rayonnées dans la plage de fréquences jusqu'à 400 GHz sont considérées comme essentielles et ont été choisies de manière à assurer un niveau adéquat de protection de la réception radioélectrique dans l’environnement électromagnétique défini. Tous les phénomènes perturbateurs n'ont pas été inclus pour les besoins de l'essai. Seuls l'ont été ceux considérés comme pertinents pour les matériels destinés à fonctionner dans les environnements couverts par le présent document. Les exigences d’émission spécifiées dans le présent document ne sont pas destinées à s’appliquer aux transmissions intentionnelles et à leurs harmoniques provenant d’un émetteur tel que défini par l'UIT.
NOTE 1 Ce document ne traite pas des aspects de sécurité.
NOTE 2 Dans des cas particuliers, des situations apparaissent dans lesquelles les niveaux spécifiés dans le présent document n’offrent pas la protection adéquate, lorsqu’un récepteur sensible est utilisé très proche d’un matériel par exemple. Dans de tels cas, utiliser des mesures d’atténuation particulières afin de réduire tout effet éventuel.
NOTE 3 Les perturbations générées dans les conditions de défaut du matériel ne sont pas couvertes par le présent document.
NOTE 4 Les matériels conformes à l’IEC 61000-6-3 conviennent à une utilisation dans ces environnements définis.

Overview

EN IEC 61000-6-8:2020 is a generic electromagnetic compatibility (EMC) emission standard published by CLC / CENELEC (identical to IEC 61000-6-8:2020). It applies when there is no dedicated product or product-family EMC emission standard. The standard sets conducted and radiated emission requirements for professional equipment intended for commercial and light‑industrial locations, covering the frequency range 0 Hz to 400 GHz. It is intended for professionally installed and maintained equipment and is not applicable to residential use or intentional radio transmissions.

Key topics and technical requirements

• Scope & applicability
  • Applies only to professional equipment used in commercial and light‑industrial environments and professionally installed/maintained devices.
  • If in doubt, IEC 61000-6-3 (residential/commercial) prevails.
• Emission requirements
  • Conducted and radiated emission limits across 0 Hz–400 GHz to protect radio reception in the defined environment.
  • Does not cover intentional radio transmitters, safety aspects, or disturbances under fault conditions.
• Classification and ports
  • Defines equipment classification (see Clause 4) and example port types (enclosure, AC mains, DC power, other wired ports).
• Test arrangements and measurements
  • Measurement and test conditions are specified (Clause 5, Tables) including required highest frequency for radiated measurements and test site arrangements.
  • Measurement uncertainty and compliance criteria are addressed.
• Documentation
  • Requirements for user documentation and information for professional installation and maintenance (Clause 6).
• Special testing topics
  • Annexes detail examples of classification, testing of DC powered systems, rationale for DC port limits, and mitigation measures.
  • Tables provide limits and test requirements for enclosure ports, mains ports, DC power ports and other wires.

Practical applications and who uses this standard

• Manufacturers and product designers of professional electrical/electronic equipment for offices, commercial premises, light industrial sites - to design for compliant emissions.
• EMC engineers and test labs - to plan and execute conducted and radiated emission tests and interpret results per IEC 61000-6-8.
• Compliance and certification bodies - to assess conformity when no product-specific emission standard exists.
• System integrators and installers - to understand installation/maintenance obligations and mitigation techniques when deploying professional equipment.
• Procurement and facility managers - to specify EMC requirements for equipment used in commercial/light‑industrial environments.

Related standards

• IEC 61000-6-3 (emission standard for residential/commercial locations)
• CISPR 16 series (measurement apparatus and methods)
• IEC 61000-3-2 / 3-3 / 3-11 / 3-12 (limits for harmonic currents, flicker and related mains interaction)
• CISPR 32 (multimedia equipment emission requirements)

EN IEC 61000-6-8 is a key generic EMC emission reference for professional equipment in commercial and light‑industrial settings; use it for test planning, product compliance and mitigation guidance when no dedicated product standard is available.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-8: Generic standards – Emission standard for professional
equipment in commercial and light-industrial locations

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-8: Generic standards – Emission standard for professional
equipment in commercial and light-industrial locations

1 Scope
This generic EMC emission standard 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.

4 Classification of equipment
This document applies to equipment intended to be used within commercial and light-industrial
(see 3.1.3) locations that satisfies all the restrictions of use defined within the scope (see
Clause 1). For this equipment, the requirements of Table 3 to Table 6 apply.
These requirements are not intended to offer adequate protection to radio services and
applications within the residential environment.
NOTE Examples of the emission classification of equipment and mapping to the immunity standard is given in
Annex A.
5 Measurements and conditions during testing
Measurements shall be conducted in a defined and reproducible manner.
The measurements may be performed in any order.
The description of the measurement, the measurement instrumentation, the measurement
methods and the measurement set-up to be used are given in the standards, which are referred
to in Table 3 to Table 6. The contents of these standards are not repeated here, however
modifications or additional information needed for the practical application of the measurements
are given in this document.
The EUT shall be tested in the operating mode producing the largest emission in the frequency
band being assessed, consistent with intended use. The configuration of the test sample shall
be varied to achieve maximum emission consistent with typical use and installation practice.
NOTE Pre-testing can be used to reduce test time.
If the EUT is part of a system, or can be connected to associated equipment, the EUT shall be
tested while connected to the minimum representative configuration of associated apparatus
necessary to exercise the ports in a similar manner to that described in CISPR 32. If the EUT
has a large number of similar ports or ports with many similar connections, a sufficient number
shall be selected to simulate actual operating conditions and to ensure that all the different
types of termination are covered.
In cases where the equipment instructions requires external filtering, shielding devices or
similar measures, these measures shall be applied during the measurements.
The EUT shall be arranged in accordance with the requirements of Table 1.

– 14 – IEC 61000-6-8:2020 © IEC 2020
Table 1 – Test arrangements of EUT
Intended operational Test arrangement Remarks
arrangement(s) of EUT
Table-top only Table-top
Floor-standing only Floor-standing 2
See table clause 3.3 for testing in a
FAR
Can be floor-standing or table-top Table-top
Rack mounted In a rack or table-top
Other, for example wall mounted, Table-top With normal orientation
ceiling mounted, handheld, body
If the equipment is designed to be
worn
mounted on a ceiling, the downward-
facing portion of the EUT may be
oriented facing upward.
If a physical hazard would be caused by testing the device on a table-top, then it may be tested as floor standing
and the test report shall document the decision and justification.

The configuration and mode of operation during the measurements shall be documented in the
test report.
The measurements shall be carried out at one single set of parameters within the operating
ranges of temperature, humidity and atmospheric pressure specified for the product and at the
rated supply voltage, unless otherwise indicated in the basic standard. The relevant conditions
shall be recorded in the test report.
Where applicable, additional information on EUT configuration can be found in the CISPR 16-2-
1, CISPR 16-2-3 or CISPR 32 as referenced in Table 3 to Table 6.
6 Documentation for the user
In principle, the equipment instructions for use should provide information on mitigation
measures that can be used to reduce emissions from the installed equipment, to similar levels
of radio protection as defined in IEC 61000-6-3 but at the boundary of the premises. This also
includes the low voltage AC power network.
NOTE 1 In this context, premises means a building together with its land and outbuildings occupied by a business.
For example, an apartment above a shop would not be contained within the premises.
NOTE 2 For guidance on in-situ measurements refer to 7.7 of CISPR 16-2-3:2016, 7.6 of CISPR 16-2-1:2014 and
CISPR 11.
The equipment instructions for use shall include the following:
• a statement that the equipment meets the requirements for commercial and light-industrial
(see 3.1.3) locations when professionally installed and maintained,
• if any special measures have to be taken to achieve compliance,
EXAMPLE 1 The instructions for use could require the use of shielded or special cables.
• any specific installation instructions to minimize emissions,
EXAMPLE 2 The instructions for use could define requirements for earthed arrangements or the installation of
blanking panels.
___________
In this document, table clauses are referenced using an x.y format, where x denotes the table and y denotes the
referenced clause by row within the table. For example table clause 3.1 is Table 3, clause (row) 1.

IEC 61000-6-8:2020 © IEC 2020 – 15 –
• the installation and any maintenance requires a professional (see 3.1.14) with relevant EMC
experience to install specific EMC mitigation measures defined in the user instructions;
examples of mitigation measurements are defined in Annex D.
• a notice stating:
The professional installer shall evaluate the EMC situation before installation, if the
equipment is installed closer than 30 m to a residential location.
• an additional notice stating:
Caution: This equipment is not intended for use in residential locations and will not
guarantee to provide adequate protection to radio reception in such locations
7 Applicability
The application of measurements for emission(s) depends on the particular equipment, its
configuration, its ports, its technology and its operating conditions.
Measurements shall be applied to the relevant ports of the equipment specified in Table 3 to
Table 6. Measurements shall only be carried out where the relevant ports exist.
All tests defined in Table 3 to Table 6 shall be considered by the test plan, however, where it
has been determined in the test plan, that one or more of the tests are not applicable, the
decision and justification not to perform such tests shall be recorded in the test report. See
examples.
EXAMPLE When considering a test plan for an EUT, which is always powered through a UPS, then conducted tests
on the low voltage AC mains port are not necessary.
8 Emission requirements
The requirements are given in Table 3 to Table 6.
9 Measurement uncertainty
Where guidance for the calculation of the instrumentation uncertainty of a measurement is
specified in CISPR 16-4-2, this shall be followed. For these measurements the determination
of compliance with the limits in this document shall take into consideration the measurement
instrumentation uncertainty in accordance with CISPR 16-4-2. Calculations to determine the
measurement result and any adjustment of the test result required when the test laboratory
uncertainty is larger than the value for U given in CISPR 16-4-2 shall be included in the test
cispr
report.
10 Compliance with this document
Where this document gives options for testing particular requirements with a choice of test
methods, compliance can be shown against any of the relevant test methods, using the
specified limits within the restrictions provided in the relevant table clauses. For example, floor
standing equipment shall be assessed against table clause 3.1, considering table clause 3.2 is
limited to small equipment and table clause 3.3 is limited to table top equipment.
In any situation where it is necessary to retest the equipment the test method originally chosen
shall be used in order to ensure consistency of the results.
The test report shall contain sufficient details to facilitate reproducibility of the measurements.
