Overview
EN IEC 61326-2-4:2021 (IEC 61326-2-4:2020) is a part-specific European/International standard that defines EMC requirements for electrical equipment used in measurement, control and laboratory environments. It provides detailed test configurations, operational conditions and performance criteria specifically for:
- Insulation monitoring devices (IMDs) - per IEC 61557-8, and
- Equipment for insulation fault location - per IEC 61557-9.
This edition (third) updates and supplements IEC 61326-1:2020, replacing EN 61326-2-4:2013 and aligning EMC testing and performance expectations for devices permanently or semi-permanently connected to distribution systems.
Key topics and technical requirements
EN IEC 61326-2-4:2021 focuses on practical EMC compliance elements for IMDs and fault-location equipment:
- EMC test plan and test configurations: Defines how the Equipment Under Test (EUT) must be connected and exercised during immunity and emission testing.
- Operational conditions: Specifies quiescent and operate modes and the required conditions during tests.
- Immunity requirements: Details applicable immunity tests (electrostatic discharge, radiated and conducted disturbances, etc.) and conditions tailored to insulation monitoring and fault-location functions.
- Emission requirements: Sets measurement conditions and reference to emission limits (as applied from IEC 61326-1).
- Performance criteria: Establishes functional performance levels to judge pass/fail under EMC stress-how the device must behave during and after disturbances.
- Test reporting and instructions for use: Guidance on documenting test results and what information manufacturers should include in user documentation.
- Annex A: Special immunity test requirements for portable test and measurement equipment powered by battery or the measured circuit.
Practical applications
This standard is directly applicable to:
- Design, EMC testing and certification of insulation monitoring devices for IT (unearthed) power systems.
- Development and qualification of insulation fault location systems used in industrial and low-voltage distribution networks.
- Ensuring reliable operation of safety- and availability-critical monitoring equipment under electromagnetic disturbances.
Who should use this standard
- EMC and compliance engineers designing IMDs and fault-location equipment
- Manufacturers and product managers in power protection and test-equipment sectors
- Test laboratories performing EMC qualification and certification
- System integrators and asset owners specifying compliance for distribution network monitoring

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.
International Standard IEC 61326-2-4 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement, control and
automation.

L'un des principaux atouts de cette norme est qu'elle va au-delà des prescriptions générales énoncées dans la norme IEC 61326-1, fournissant des spécifications détaillées qui sont essentielles pour assurer la fiabilité et la précision des dispositifs de surveillance de l'isolation. Les configurations d'essai bien définies permettent une évaluation rigoureuse des performances, ce qui est crucial pour le bon fonctionnement des systèmes d'alimentation électrique. En outre, la pertinence de cette norme se manifeste dans son adaptation aux appareils connectés de manière permanente ou semi-permanente au système de distribution. Cela garantit que les pratiques de sécurité et de performance sont maintenues, particulièrement dans les environnements où la détection des défauts d'isolation est primordiale. Ces caractéristiques renforcent non seulement la conformité avec les normes internationales, mais aussi la confiance des utilisateurs quant à la sécurité et au rendement de leurs installations. En somme, la norme SIST EN IEC 61326-2-4:2021 représente un document essentiel pour les fabricants et les utilisateurs d'équipements de mesure et de contrôle, assurant l'intégrité des dispositifs de surveillance de l'isolation et l'efficacité des systèmes associés.
