LED MODULES FOR GENERAL LIGHTING –
SAFETY SPECIFICATIONS

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 62031 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 2008,
Amendment 1:2012 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the scope was clarified as well as the wording in several other clauses;
b) the normative references were updated;
c) the definitions for "replaceable LED module", "non-replaceable LED module" and "non-
user replaceable LED module" were introduced while other definitions covered by
IEC 62504 have been removed;
d) the marking clause was restructured and a table added to provide an informative overview;
e) the marking requirements for built-in LED modules were changed;

f) the entry for the marking with the working voltage was revised;
g) the provisions for terminals and heat management were revised;
h) Annex B was deleted;
i) information for luminaire design with regard to working voltage and water contact was
introduced;
j) an abnormal temperature test was introduced.

quotient of an ultraviolet hazard quantity to the corresponding photometric quantity
Note 1 to entry: Ultraviolet hazard efficacy of luminous radiation is expressed in mW/klm.
Note 2 to entry: The ultraviolet hazard efficacy of luminous radiation is obtained by weighting the spectral power
distribution of the lamp or LED module with the UV hazard function S (λ). Information about the relevant UV
UV

beings. It does not deal with the possible influence of optical radiation on materials, such as mechanical damage or
discoloration.
3.2
replaceable LED module

Note 1 to entry: When incorporated into a luminaire, a replaceable LED module can be classified as replaceable,
non-user replaceable or non-replaceable depending on the luminaire design.
3.3
non-replaceable LED module
LED module designed to be a non-replaceable part of the luminaire

4 General requirements
4.1 LED modules shall be so designed and constructed that they operate without danger to
the user or surroundings when used as intended (see manufacturer’s instructions).
NOTE IEC 61347-1:2015, Annex S gives examples of insulation coordination which can be appropriate for LED
modules.
4.2 LED modules shall be classified, according to the method of installation, as:
– built-in,
– independent, or
– integral.
4.3 For non-integrated LED modules and semi-integrated LED modules, all electrical
measurements, unless otherwise specified, shall be carried out at voltage limits (min/max),
current limits (min/max) or power limits (min/max) and minimum frequency, in a draught-free
room at the temperature limits of the allowed range specified by the manufacturer. Unless the
manufacturer indicates the most critical combination, all combinations (min/max) of
voltage/current/power and temperature shall be tested.
4.4 For integrated LED modules, the electrical measurements shall be carried out at the
tolerance limit values of the rated supply voltage.
4.5 Integral LED modules not having their own enclosure shall be regarded as integral
components of luminaires according to IEC 60598-1:2014, 0.5.1.
4.6 In addition to the requirements of this document, independent LED modules shall
comply with IEC 60598-1:2014 and IEC 60598-1:2014/AMD1:2017.
4.7 If the LED module is a factory sealed unit, it shall not be opened for any tests. In case
of doubt based on the inspection of the LED module and the examination of the circuit
diagram, and in agreement with the manufacturer or responsible vendor, such specially
prepared LED modules shall be submitted for testing so that a fault condition can be
simulated.
4.8 For LED modules with integrated controlgear providing SELV, the requirements
according to IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, Clauses L.5, L.6, L.7, L.8,
L.9, L.10, and L.11 apply.
5 General test requirements
5.1 Tests according to this document shall be type tests.
NOTE The requirements and tolerances in this document are related to testing of a type-test sample submitted by
the manufacturer for that purpose.
Conformity of production is the responsibility of the manufacturer and can need routine tests and quality assurance
in addition to type testing.

---------------------- Page: 14 ----------------------
SIST EN IEC 62031:2020
IEC 62031:2018 © IEC 2018 – 9 –
5.2 The test shall be carried out at an ambient temperature of 10 °C to 30 °C. If the
manufacturer specifies a different ambient termperature, this shall be used as test
temperature.
5.3 Unless otherwise specified, the type test shall be carried out on one sample consisting
of one or more items submitted for the purpose of the type test.
In general, all tests shall be carried out on each type of LED module or, where a range of
similar LED modules is involved, for each power in the range or on a representative selection
from the range, as agreed with the manufacturer.
5.4 If the light output has substantially changed, the LED module shall not be used for
further tests.
NOTE Usually, a value of 50 % indicates irreversible changes in the LED module.
5.5 Testing of integral LED modules not having their own enclosure shall be done as part of
the luminaire as far as applicable.
