Overview

IEC 63044-5-2:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the electromagnetic compatibility (EMC) requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS). This part of the IEC 63044 series focuses specifically on EMC requirements for HBES/BACS devices and networks that are intended for use in residential, commercial, and light-industrial environments.

The standard sets the minimum immunity and emission performance levels for devices within HBES/BACS networks, covering devices without dedicated EMC product standards and interfaces connected to HBES/BACS systems. It provides guidance on maintaining system reliability and minimizing electromagnetic interference in small to medium-scale building automation contexts.

Key Topics

• Scope and Applicability
  IEC 63044-5-2 targets EMC requirements for HBES/BACS installations in environments defined by IEC 61000-6-1, including homes, office buildings, shops, and light industrial sites. It supports a broad range of networked equipment, such as operator stations, control devices, field devices, and their interfaces.

• Immunity Requirements
  The standard defines detailed immunity criteria for different parts of HBES/BACS devices:

  • Enclosures (housing the equipment)
  • HBES/BACS network ports
  • Signal ports
  • DC power ports
  • AC power ports
    Testing against common EMC disturbances like electrostatic discharge, radiated radio-frequency electromagnetic fields, electrical fast transient bursts, surge, and power frequency magnetic fields is mandated to ensure device robustness.

• Emission Requirements
  IEC 63044-5-2 also specifies the maximum allowable electromagnetic emissions to reduce the risk of interference affecting other equipment and systems within the environment.

• Testing and Performance Criteria
  In conjunction with IEC 63044-5-1, the document outlines standard test conditions, performance criteria, and test methodologies that manufacturers should follow to verify EMC compliance.

Applications

IEC 63044-5-2 is critical for manufacturers, system integrators, and building managers involved in:

• Home Automation Systems
  Ensuring smart lighting, HVAC control, security, and energy management solutions comply with EMC standards to deliver reliable operation in residential environments.

• Commercial Building Automation
  Providing EMC-tested control systems for offices, retail spaces, and public buildings where multiple electronic systems coexist.

• Light Industrial Automation
  Supporting automation systems in light-industrial zones where electromagnetic environments can vary but strict immunity and emission limits are necessary for operational integrity.

• Networked Devices and Interfaces
  Covering devices connected within HBES/BACS networks that may not yet have dedicated EMC standards, promoting system-wide electromagnetic compatibility.

Compliance with IEC 63044-5-2 helps reduce failures and downtime caused by electromagnetic disturbances, enhances user safety, and supports regulatory approval processes in global markets.

Related Standards

IEC 63044-5-2 works alongside several key standards, including:

• IEC 63044-5-1:2017 – Details general EMC requirements, conditions, and test set-up for HBES/BACS devices.
• IEC 61000 Series – Provides comprehensive EMC testing techniques and immunity standards, including:
  • IEC 61000-4-2: Electrostatic Discharge Immunity Testing

Part 5-2: EMC requirements for HBES/BACS used in residential,
commercial and light-industrial environments

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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 63044-5-2 edition 1.1 contains the first edition (2017-01) [documents 23/737/CDV
and 23/749/RVC] and its amendment 1 (2022-06) [documents 23/1002/FDIS and
23/1008/RVD].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l’IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les
dépenses découlant de la publication ou de l'utilisation de cette Publication de l’IEC ou de toute autre
Publication de l’IEC, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de l’IEC peuvent faire
l’objet de droits de brevet. L’IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.

J ≤ (3C + 1)/40
où la gigue J et la taille du caractère C sont exprimées en millimètres.
Comme la gigue est linéairement proportionnelle au champ magnétique, les essais peuvent être effectués en
utilisant d'autres niveaux d’essai en extrapolant le niveau de gigue maximal de manière appropriée.
