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.

4 Classification
LED modules are classified, according to the level of controlgear integration, as:
– integrated LED modules, LEDi module,
– semi-integrated LED modules, LEDsi module, or
– non-integrated LED modules, LEDni module.
5 General requirements
LED modules shall be so designed and constructed that, for their intended use, they cause no
danger to the users or surroundings.
Parts of LED modules providing hazard protection shall not become loose during normal
operation and handling.
Requirements, tests and compliances are provided in this document to reduce the risk of harm
to a tolerable level under normal operating conditions, abnormal operating conditions and single
fault conditions.
Where the terms "voltage" and "current" are used in this document, they imply the RMS values
unless otherwise stated.
Annex B and Annex C provide information for luminaire design and information for controlgear
design, respectively.
6 General notes on tests
6.1 General
6.1.1 Type test
Tests according to this document are type tests.
NOTE The requirements and tolerances specified in this document are related to testing of a type test sample
submitted by e.g. the manufacturer for that purpose. Compliance of type test samples does not ensure compliance
of the whole production of a manufacturer with this document. Conformity of production is the responsibility of the
manufacturer, and routine tests and quality insurance in addition to the type test can be necessary.
6.1.2 Test samples
Tests shall be carried out with type test samples.
NOTE 1 For example, damage to marking as a result of the marking test has no impact on electrical testing, thus
the LED module is still considered to be representative of production for other tests.
Unless otherwise specified in this document, the type test shall be carried out on one sample
consisting of one or more sample items submitted for the purpose of the type test.
All tests shall be carried out on each type of the LED module. Where there is a range of similar
LED modules for testing, samples representing the most onerous case within the range shall
be selected as relevant to the test criteria.
NOTE 2 As an example, it is not necessary to carry out overload condition tests separately on LED modules of one
type having different colour temperatures.
NOTE 3 It can be helpful to contact the manufacturer for information on a range of similar LED modules.
LED modules shall not be altered for the purposes of testing where the results of the tests could
be affected. Specially prepared sample items may be used, where necessary.
6.1.3 Compliance by inspection of relevant data
Where in this document compliance of materials, components or subassemblies is checked by
inspection or by testing of properties, compliance may be confirmed by reviewing any relevant
data or previous test results that are available.
6.2 Default test conditions
6.2.1 General
Unless otherwise specified in this document, the tests shall be conducted under the most
onerous operating conditions within the specified operating range. In addition to 6.2.2 and 6.2.3
the following parameters shall be taken into account:
– operating mode, including loading by external connected equipment;
– control settings and dimming conditions;
– position of movable parts;
– orientation.
NOTE It can be helpful to contact the manufacturer for information on the most onerous test conditions.
6.2.2 Electrical supply conditions
6.2.2.1 General
The supply voltage, current and frequency shall be stabilized within ± 1 % of the specified test
value. The peak-to-peak ripple of the DC test current or voltage shall not exceed 10 % of the
average value of the test current or voltage.
6.2.2.2 LED modules supplied by voltage sources
LED modules supplied by voltage sources usually comprise means to adjust their operating
current so they can be supplied by a voltage source that, ideally, has no impedance.
EXAMPLE 1 Mains supplied integrated LED modules (LEDi modules) and semi-integrated LED modules (LEDsi
modules).
Tests shall be carried out at the rated voltage, or at the most onerous value within the boundary
of rated voltage range, if not otherwise specified in this document.
For LED modules having alternative rated voltages or voltage ranges, tests shall be carried out
separately for each rated voltage or voltage range.
For AC rated LED modules, tests shall be carried out at the most onerous rated frequency.
For LED modules rated for both AC and DC, each test shall be carried out with the most onerous
voltage source condition.
Where LED modules are intended for operation on a battery supply, a DC power source may
supply the LED module under test, provided that the source impedance is equivalent to that of
a battery.
EXAMPLE 2 A non-inductive capacitor of appropriate rated voltage and with a capacitance of at least 50 μF
connected across the supply terminals of the units under test normally provides a source impedance simulating that
of a battery.
6.2.2.3 LED modules supplied by current sources
LED modules supplied by current sources usually do not comprise means to adjust their
operating current, the operating voltage of such LED modules results from the design and the
operating current.
EXAMPLE Non-integrated LED module (LEDni module).
Tests shall be carried out at the maximum rated current.
6.2.3 Ambient test conditions
Tests shall be carried out at an ambient temperature within the range of 10 °C to 30 °C unless
otherwise specified in this document.

AVANT-PROPOS
1) La Commission Électrotechnique 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. À 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'IEC attire l'attention sur le fait que la mise en application du présent document peut entraîner l'utilisation d'un
ou de plusieurs brevets. L'IEC ne prend pas position quant à la preuve, à la validité et à l'applicabilité de tout
droit de brevet revendiqué à cet égard. À la date de publication du présent document, l'IEC n'avait pas reçu
notification qu'un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois, il y a lieu
d'avertir les responsables de la mise en application du présent document que des informations plus récentes
sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse https://patents.iec.ch.
L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevets.
L'IEC 62031 a été établie par le sous-comité 34A: Sources lumineuses électriques, du comité
d'études 34 de l'IEC: Éclairage. Il s'agit d'une Norme internationale.

Les modules LED sont classés en fonction du niveau d'intégration de l'appareillage de
commande, comme suit:
– modules LED intégrés, modules LEDi;
– modules LED semi-intégrés, modules LEDsi; ou
– modules LED non intégrés, modules LEDni.
5 Exigences générales
Les modules LED doivent être conçus et construits de telle sorte qu'ils ne présentent aucun
danger pour les utilisateurs ou l'environnement pendant l'utilisation prévue.
Les parties des modules LED qui assurent une protection contre les dangers ne doivent pas
prendre de jeu en conditions normales de fonctionnement et de manutention.
Les exigences, les essais et la conformité sont fournis dans le présent document pour réduire
le risque de dommage à un niveau tolérable dans les conditions normales de fonctionnement,
les conditions anormales de fonctionnement et les conditions de premier défaut.
Sauf indication contraire, lorsque les termes "tension" et "courant" sont utilisés dans le présent
document, ils font référence aux valeurs efficaces.
L'Annexe B et l'Annexe C fournissent respectivement des informations relatives à la conception
des luminaires et des informations relatives à la conception des appareillages de commande.
6 Généralités sur les essais
6.1 Généralités
6.1.1 Essai de type
Les essais spécifiés dans le présent document sont des essais de type.
NOTE Les exigences et les tolérances spécifiées dans le présent document s'appliquent aux essais d'un échantillon
pour essai de type soumis, par exemple, par le fabricant dans ce but. La conformité des échantillons pour essai de
type ne préjuge pas de celle de la production totale d'un fabricant au présent document. La conformité de la
production est de la responsabilité du fabricant, et des essais individuels de série et une assurance qualité peuvent
être nécessaires en complément de l'essai de type.
6.1.2 Échantillons d'essai
Les essais doivent être réalisés avec des échantillons pour essai de type.
NOTE 1 Par exemple, les dommages aux marquages dus à l'essai de marquage n'ont aucun effet sur les essais
électriques, de sorte que le module LED est toujours considéré comme étant représentatif de la production pour
d'autres essais.
Sauf spécification contraire dans le présent document, l'essai de type doit être réalisé sur un
échantillon constitué d'une ou plusieurs entités d'échantillonnage présentées en vue de l'essai
de type.
Tous les essais doivent être réalisés sur chaque type de module LED. Lorsqu'il existe une série
de modules LED similaires pour les essais, les échantillons représentant le cas le plus
défavorable de la série doivent être choisis en fonction des critères d'essai.
NOTE 2 À titre d'exemple, il n'est pas nécessaire d'effectuer séparément des essais de condition de surcharge sur
des modules LED d'un type ayant des températures de couleur différentes.
NOTE 3 Il peut être utile de contacter le fabricant pour obtenir des informations sur une série de modules LED
similaires.
Les modules LED ne doivent pas être altérés pour les besoins des essais lorsque les résultats
des essais peuvent s'en trouver modifiés. Des entités d'échantillonnage spécialement
confectionnées peuvent être utilisées, si cela est nécessaire.
6.1.3 Conformité par examen des données pertinentes
Lorsque, dans le présent document, la conformité des matériaux, composants ou
sous-ensembles est vérifiée par examen ou par essai des propriétés, la conformité peut être
confirmée par un examen des données pertinentes ou des résultats d'essais antérieurs disponibles.
6.2 Conditions d'essai par défaut
6.2.1 Généralités
Sauf spécification contraire dans le présent document, les essais doivent être effectués dans
les conditions de fonctionnement les plus défavorables dans la plage de fonctionnement
spécifiée. En complément de 6.2.2 et 6.2.3, les paramètres suivants doivent être pris en compte:
– le mode de fonctionnement, y compris la charge par des équipements connectés externes;
– les réglages de commande et les conditions de gradation;
– la position des parties mobiles;
– l'orientation.
NOTE Il peut être utile de contacter le fabricant pour obtenir des informations sur les conditions d'essai les plus
défavorables.
6.2.2 Conditions d'alimentation électrique
6.2.2.1 Généralités
La tension d'alimentation, le courant et la fréquence doivent être stabilisés à ± 1 % de la valeur
d'essai spécifiée. L'ondulation crête à crête de l'intensité ou de la tension d'essai en courant
continu ne doit pas dépasser 10 % de la valeur moyenne de l'intensité ou de la tension d'essai.
6.2.2.2 Modules LED alimentés par des sources de tension
Les modules LED alimentés par des sources de tension comportent généralement des moyens
de réglage de leur courant de fonctionnement, de sorte qu'ils puissent être alimentés par une
source de tension qui, dans l'idéal, n'a pas d'impédance.
EXEMPLE 1 Modules LED intégrés (modules LEDi) et modules LED semi-intégrés (modules LEDsi) alimentés par
le réseau.
Sauf spécification contraire dans le présent document, les essais doivent être effectués à la
tension assignée ou à la valeur la plus défavorable dans les limites de la plage de tensions
assignées.
Pour les modules LED possédant des tensions assignées ou des plages de tensions assignées
alternatives, les essais doivent être réalisés séparément pour chaque tension assignée ou
chaque plage de tensions assignées.
Pour les modules LED fonctionnant en courant alternatif, les essais doivent être effectués à la
fréquence assignée la plus défavorable.
Pour les modules LED fonctionnant à la fois en courant alternatif et en courant continu, chaque
essai doit être effectué dans la condition de source de tension la

LED modules - Safety requirements
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62031 has been prepared by subcommittee 34A: Electric light sources, of IEC technical
committee 34: Lighting. It is an International Standard.
This third edition cancels and replaces the second edition published in 2018. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Complete review of the document structure, detailed technical requirements and tests,
including but not limited to what is individually described under items b) to i);
b) Clarification of the scope and revision of the applicability of this document to independent
and integral LED modules;
c) Updated terms and definitions;
d) Clearer specification for clause general requirements and clause general test requirements;
e) Update of the marking clause, such as marking of control terminals;
f) A full review and update of the electrical safety, thermal safety, and mechanical safety
requirements preventing misinterpretation and ambiguity;
g) Updated photobiological safety requirements;
h) Revised and updated fault conditions and abnormal conditions requirements;
i) Removal of the annex relating to conformity testing during manufacture.
The text of this International Standard is based on the following documents:

4 Classification
LED modules are classified, according to the level of controlgear integration, as:
– integrated LED modules, LEDi module,
– semi-integrated LED modules, LEDsi module, or
– non-integrated LED modules, LEDni module.
5 General requirements
LED modules shall be so designed and constructed that, for their intended use, they cause no
danger to the users or surroundings.
Parts of LED modules providing hazard protection shall not become loose during normal
operation and handling.
Requirements, tests and compliances are provided in this document to reduce the risk of harm
to a tolerable level under normal operating conditions, abnormal operating conditions and single
fault conditions.
Where the terms "voltage" and "current" are used in this document, they imply the RMS values
unless otherwise stated.
Annex B and Annex C provide information for luminaire design and information for controlgear
design, respectively.
6 General notes on tests
6.1 General
6.1.1 Type test
Tests according to this document are type tests.
NOTE The requirements and tolerances specified in this document are related to testing of a type test sample
submitted by e.g. the manufacturer for that purpose. Compliance of type test samples does not ensure compliance
of the whole production of a manufacturer with this document. Conformity of production is the responsibility of the
manufacturer, and routine tests and quality insurance in addition to the type test can be necessary.
6.1.2 Test samples
Tests shall be carried out with type test samples.
NOTE 1 For example, damage to marking as a result of the marking test has no impact on electrical testing, thus
the LED module is still considered to be representative of production for other tests.
Unless otherwise specified in this document, the type test shall be carried out on one sample
consisting of one or more sample items submitted for the purpose of the type test.
All tests shall be carried out on each type of the LED module. Where there is a range of similar
LED modules for testing, samples representing the most onerous case within the range shall
be selected as relevant to the test criteria.
NOTE 2 As an example, it is not necessary to carry out overload condition tests separately on LED modules of one
type having different colour temperatures.
NOTE 3 It can be helpful to contact the manufacturer for information on a range of similar LED modules.
LED modules shall not be altered for the purposes of testing where the results of the tests could
be affected. Specially prepared sample items may be used, where necessary.
6.1.3 Compliance by inspection of relevant data
Where in this document compliance of materials, components or subassemblies is checked by
inspection or by testing of properties, compliance may be confirmed by reviewing any relevant
data or previous test results that are available.
6.2 Default test conditions
6.2.1 General
Unless otherwise specified in this document, the tests shall be conducted under the most
onerous operating conditions within the specified operating range. In addition to 6.2.2 and 6.2.3
the following parameters shall be taken into account:
– operating mode, including loading by external connected equipment;
– control settings and dimming conditions;
– position of movable parts;
– orientation.
NOTE It can be helpful to contact the manufacturer for information on the most onerous test conditions.
6.2.2 Electrical supply conditions
6.2.2.1 General
The supply voltage, current and frequency shall be stabilized within ± 1 % of the specified test
value. The peak-to-peak ripple of the DC test current or voltage shall not exceed 10 % of the
average value of the test current or voltage.
6.2.2.2 LED modules supplied by voltage sources
LED modules supplied by voltage sources usually comprise means to adjust their operating
current so they can be supplied by a voltage source that, ideally, has no impedance.
EXAMPLE 1 Mains supplied integrated LED modules (LEDi modules) and semi-integrated LED modules (LEDsi
modules).
Tests shall be carried out at the rated voltage, or at the most onerous value within the boundary
of rated voltage range, if not otherwise specified in this document.
For LED modules having alternative rated voltages or voltage ranges, tests shall be carried out
separately for each rated voltage or voltage range.
For AC rated LED modules, tests shall be carried out at the most onerous rated frequency.
For LED modules rated for both AC and DC, each test shall be carried out with the most onerous
voltage source condition.
Where LED modules are intended for operation on a battery supply, a DC power source may
supply the LED module under test, provided that the source impedance is equivalent to that of
a battery.
EXAMPLE 2 A non-inductive capacitor of appropriate rated voltage and with a capacitance of at least 50 μF
connected across the supply terminals of the units under test normally provides a source impedance simulating that
of a battery.
6.2.2.3 LED modules supplied by current sources
LED modules supplied by current sources usually do not comprise means to adjust their
operating current, the operating voltage of such LED modules results from the design and the
operating current.
EXAMPLE Non-integrated LED module (LEDni module).
Tests shall be carried out at the maximum rated current.
6.2.3 Ambient test conditions
Tests shall be carried out at an ambient temperature within the range of 10 °C to 30 °C unless
otherwise specified in this document.
