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.

INTRODUCTION to Amendment 1
The light output of LED light sources depends also on the temperature at which it is operated.
Typically the temperature is controlled by a heat sink on which it is mounted (e.g. luminaire
surface).
For this reason, the calculation of the ratio of the electrical parameter (EOF ) will be
x
introduced in the LED controlgear standards IEC 61347-2-13 and IEC 61347-2-7, as the direct
measurement of EBLF is not practicable.
In particular EOF is defined as the ratio of the current in emergency mode from constant
I
current controlgear divided by the nominal current of LED (I ):
normal mode
EOF = I / I
I emergency normal mode
Knowing that the light output of an LED light source is nearly directly proportional with the
foreward current flowing through it, it is possible to calculate the luminous flux of the luminaire
in emergency mode by using the EOF or I from constant current controlgear
.
I emergency
This document contains a proposal for the modification of IEC 60598-2-22 to use the factor
EOF or I in the luminaire.
I emergency
Any non-linearity due to the increased efficacy at lower operation temperature leads to an increased tolerance
of the light output in the emergency mode but always positive.

requirements for electronic controlgear for emergency lighting in the appropriate annex of the
standards (e.g. Annex J of IEC 61347-2-3:2011).
Compliance is checked by the relevant tests specified in these standards.
22.7.3 Emergency luminaires shall be equipped with a protection device which disconnects
the luminaire from the supply in case of any failure within that luminaire affecting the circuit
(short circuit or overcurrent consumption).
Compliance is checked by measurement and inspection.
22.7.4 For emergency luminaires, the mechanical strength tests given in Part 1 shall be
applied with a minimum impact energy of 0,35 Nm to all external parts.
22.7.5 Whilst connected to a live supply, self-contained emergency luminaires shall have
adequate separation between the normal supply and live parts in the circuit for battery ESSS
charging. When there are exposed live parts, double insulation, reinforced insulation, earth
screen or other equivalent techniques can be used.
Additionally, in the event of bare contacts in the battery ESSS charging circuit, a safety
isolating transformer shall be used. If a separating transformer is used as insulation between
the normal supply and the battery ESSS charging circuit, the insulation in the battery ESSS
charging circuit shall consist of at least basic insulation.
Compliance is checked by inspection and by the tests of Clauses 22.8 and 22.15.
22.7.6 In centrally supplied combined emergency luminaires, electrical separation between
normal and emergency supplies shall be ensured by double insulation, reinforced insulation,
earthed screen or other equivalent means.
EXAMPLE The use of basic insulation only, for both circuits, or double/ or reinforced insulation on the normal
supply circuit fulfils this requirement. The connection of both circuits to a terminal block where the required
creepage/ and clearances are obtained by leaving one terminal free, without the possibility of connection between
the circuits, is also acceptable.
Compliance is checked by inspection.
22.7.7 Self-contained emergency luminaires shall have adjacent to them or incorporated in
them a device for charging the battery ESSS from the normal supply and an indicator visible
in normal use, for example a lamp, which shows the following conditions:
a) the luminaire is connected and the charge of the battery ESSS is being maintained;
b) circuit continuity exists through the tungsten filament of emergency lighting lamps where
appropriate.
Where an electrical light source indicator is used, it shall comply with the colour requirements
of IEC 60073 and be green.
For emergency luminaires with tungsten filament lamp(s) both a) and b) apply at the same
time, and for other emergency luminaires without tungsten filaments, such as fluorescent and
LED lamps, only a) applies.
For emergency luminaires with tungsten filament lamps, compliance that circuit continuity
exists through the tungsten filament is checked in the following manner: disconnection of one
of the lamps, or all the lamps when connected in parallel, causes the indicator to extinguish or
change colour in accordance with IEC 60073.
For all emergency luminaires, compliance that the charge indicator is correctly connected to
the circuit is checked in the following manner: disconnection of the battery ESSS during the
charging phase, causes the indicator to extinguish or change colour in accordance with
IEC 60073.
22.7.8 Self-contained emergency luminaires shall incorporate a battery an ESSS that meets
the requirements of Annex A and is designed to provide the rated duration for at least four
years of normal operation. This battery ESSS shall be used only for emergency related
functions within the luminaire or its satellite.
Compliance is checked by inspection and the tests of Annex A.
22.7.9 Void
22.7.10 In self-contained emergency luminaires, there shall be no manual or non-self-
resetting circuits between the battery ESSS and emergency lighting lamps other than the
changeover device.
Self-contained emergency luminaires and centrally supplied emergency luminaires shall not
contain any manual or non-self-resetting switch isolating the emergency circuit(s) from the
mains supply other than facilities enabling rest mode or inhibition inhibiting mode.
NOTE Installation details can be found in IEC 60364-5-56.
Compliance is checked by inspection.

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.

requirements for electronic controlgear for emergency lighting in the appropriate annex of the
standards (e.g. Annex J of IEC 61347-2-3:2011).
Compliance is checked by the relevant tests specified in these standards.
22.7.3 Emergency luminaires shall be equipped with a protection device which disconnects
the luminaire from the supply in case of any failure within that luminaire affecting the circuit
(short circuit or overcurrent consumption).
Compliance is checked by measurement and inspection.
22.7.4 For emergency luminaires, the mechanical strength tests given in Part 1 shall be
applied with a minimum impact energy of 0,35 Nm to all external parts.
22.7.5 Whilst connected to a live supply, self-contained emergency luminaires shall have
adequate separation between the normal supply and live parts in the circuit for ESSS
charging. When there are exposed live parts, double insulation, reinforced insulation, earth
screen or other equivalent techniques can be used.
Additionally, in the event of bare contacts in the ESSS charging circuit, a safety isolating
transformer shall be used. If a separating transformer is used as insulation between the
normal supply and the ESSS charging circuit, the insulation in the ESSS charging circuit shall
consist of at least basic insulation.
Compliance is checked by inspection and by the tests of Clauses 22.8 and 22.15.
22.7.6 In centrally supplied combined emergency luminaires, electrical separation between
normal and emergency supplies shall be ensured by double insulation, reinforced insulation,
earthed screen or other equivalent means.
EXAMPLE The use of basic insulation only, for both circuits, or double or reinforced insulation on the normal
supply circuit fulfils this requirement. The connection of both circuits to a terminal block where the required
creepage and clearances are obtained by leaving one terminal free, without the possibility of connection between
the circuits, is also acceptable.
Compliance is checked by inspection.
22.7.7 Self-contained emergency luminaires shall have adjacent to them or incorporated in
them a device for charging the ESSS from the normal supply and an indicator visible in
normal use, for example a lamp, which shows the following conditions:

b) circuit continuity exists through the tungsten filament of emergency lighting lamps where
appropriate.
Where an electrical light source indicator is used, it shall comply with the colour requirements
of IEC 60073 and be green.
For emergency luminaires with tungsten filament lamp(s) both a) and b) apply at the same
time, and for other emergency luminaires without tungsten filaments, such as fluorescent and
LED lamps, only a) applies.
For emergency luminaires with tungsten filament lamps, compliance that circuit continuity
exists through the tungsten filament is checked in the following manner: disconnection of one
of the lamps, or all the lamps when connected in parallel, causes the indicator to extinguish or
change colour in accordance with IEC 60073.
For all emergency luminaires, compliance that the charge indicator is correctly connected to
the circuit is checked in the following manner: disconnection of the ESSS during the charging
phase, causes the indicator to extinguish or change colour in accordance with IEC 60073.
22.7.8 Self-contained emergency luminaires shall incorporate an ESSS that meets the
requirements of Annex A and is designed to provide the rated duration for at least four years
of normal operation. This ESSS shall be used only for emergency related functions within the
luminaire or its satellite.
Compliance is checked by inspection and the tests of Annex A.
22.7.9 Void
22.7.10 In self-contained emergency luminaires, there shall be no manual or non-self-
resetting circuits between the ESSS and emergency lighting lamps other than the changeover
device.
Self-contained emergency luminaires and centrally supplied emergency luminaires shall not
contain any manual or non-self-resetting switch isolating the emergency circuit(s) from the
mains supply other than facilities enabling rest mode or inhibiting mode.
NOTE Installation details can be found in IEC 60364-5-56.
Compliance is checked by inspection.
22.7.11 Lamp failure. Any lamp failure (emergency or normal operating lighting lamps) shall
not interrupt the charging current to the ESSS and shall not cause an overload that could
impair the operation of the ESSS.
Compliance is checked by the test of Clause 22.6 of IEC 61347-2-7:2011 and Clause 22.6 of
IEC 61347-2-7:2011/AMD2:2021.
