Part 2-7: Particular requirements for battery supplied electronic
controlgear for emergency lighting (self-contained)

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.

INTRODUCTION
The formatting into separately published parts provides for ease of future amendments and
revisions. Additional requirements will be added as and when a need for them is recognized.
This standard, and the parts which make up IEC 61347-2, in referring to any of the clauses of
IEC 61347-1, specify the extent to which such a clause is applicable and the order in which
the tests are to be performed; they also include additional requirements, as necessary. All
parts which make up IEC 61347-2 are self-contained and, therefore, do not include reference
to each other.
Where the requirements of any of the clauses of IEC 61347-1 are referred to in this standard
by the phrase “The requirements of Clause n of IEC 61347-1 apply", this phrase is interpreted
as meaning that all requirements of the clause in question of Part 1 apply, except any which
are clearly inapplicable to the specific type of lamp controlgear covered by this particular part
of IEC 61347-2.

LAMP CONTROLGEAR –
Part 2-7: Particular requirements for battery supplied electronic
controlgear for emergency lighting (self-contained)

1 Scope
This part of IEC 61347 specifies particular safety requirements for battery supplied electronic
controlgear for maintained and non-maintained emergency lighting purposes.
It includes specific requirements for electronic controlgear and control units for self-contained
luminaires for emergency lighting as specified by IEC 60598-2-22.
It is intended for controlgear for fluorescent lamps, but it is also applicable to other lamp types
e.g. incandescent, high pressure discharge lamps and LEDs.
This standard covers the emergency mode operation of a controlgear. For controlgear with a
combination of normal and emergency lighting operation, the normal lighting operation
aspects are covered by the appropriate part 2 of IEC 61347.
DC supplied electronic controlgear for emergency lighting may or may not include batteries.
This standard also includes operational requirements for electronic controlgear, which, in the
case of d.c. supplied electronic controlgear, are regarded as performance requirements. This
is because non-operational emergency lighting equipment presents a safety hazard. It does
not apply to d.c. supplied electronic controlgear for emergency lighting, which are intended for
connection to a centralised emergency power supply system. A centralised emergency power
system could be a central battery system.
NOTE Annex J of IEC 61347-2-3 applies to a.c., a.c./d.c. or d.c. supplied electronic controlgear for connection to
centralised emergency power supply systems that are also intended for emergency lighting operations from
a.c./d.c. supplies.

The ballast/control unit shall be designed so that the appropriate lamp(s) achieve sufficient
switchings.
Compliance is checked by the following test:
Three new lamps shall achieve 200 switchings when operated at the rated operating voltage
in a cycle: 30 s “on”, 120 “off”. If one lamp does not achieve 200 switchings, a further 3 lamps
shall be tested, each of which shall achieve 200 switchings.
The 200 switchings shall occur from normal mode with lamp-OFF, and to emergency mode
with lamp-ON.
61347-2-7 © IEC:2011 – 13 –
After this test, the ballast/control unit shall start and operate the three lamps, pre-conditioned
by 200 switchings, at the rated operating voltage.
Additionally, the same three lamps shall start and operate from the appropriate mains
operation reference ballast/circuit.
16 Lamp current
The requirements in this clause only apply to fluorescent lamps. Requirements for other light
sources are under consideration.
The controlgear shall limit the arc current delivered to a reference lamp to a value not
exceeding 125 % of that delivered to the same lamp when operated with a reference
controlgear. Measurements shall be made in 25 °C ambient temperature, the test controlgear
shall be operated at its rated operating voltage, and the appropriate reference controlgear
shall be operated at its rated voltage and frequency.
Reference lamps and ballasts shall be in compliance with IEC 60081, IEC 60901, IEC 60921
and IEC 60929.
17 Supply current
At the d.c. rated operating voltage, the supply current from the battery shall not differ by more
than ± 15 % from the declared value when the ballast is operated with a reference lamp.
The supply shall be of low impedance and low inductance (applicable only to batteries remote
from the ballast).
Compliance is checked by measurement.
18 Maximum current in any lead (with cathode preheating)
The requirements in this clause only apply to fluorescent lamps. Requirements for other light
sources are under consideration.
The current flowing in any one of the cathode terminations shall not exceed the value given in
the relevant lamp data sheets of IEC 60081 and IEC 60901.
Compliance is checked by the relevant tests ad measurements described in Clause 11 of
IEC 60929.
19 Lamp operating current waveforms
The requirements in this clause only apply to fluorescent lamps. Requirements for other light
sources are under consideration.
Ballasts shall provide the correct waveform.
The waveform of the current supplied in the steady state to a reference lamp, associated with
a ballast supplied at its rated operating voltage, shall be such that the peak current does not
exceed 1,7 times the rated lamp current as specified on the relevant lamp data sheet of
IEC 60081 and IEC 60901.
Additionally, the peak current shall not exceed 3 times the measured r.m.s. lamp current.

Compliance is checked by measurement.
20 Functional safety (EBLF)
The requirements in this clause only apply to fluorescent lamps. Requirements for other light
sources are under consideration. Measurements shall be made using a new lamp which has
been aged according to the appropriate lamp standard for initial luminous flux measurements.
The appropriate lamp associated to the controlgear shall provide the necessary light output
after changeover to the emergency mode. This is verified if the declared emergency ballast
lumen factor (EBLF) is achieved during emergency operation at 25 °C.
Compliance is checked by the following test:
Electronic controlgear provided with or without batteries:
For measurement of EBLF, voltages representative of a fully charged battery and the battery
voltage present just before lamp extinguishing are used as follows:
V – Full charge battery voltage per cell dependant on battery type as follows:
NiCd – 1,35 V per cell;
NiMh – 1,35 V per cell;
Pb – 2,10 V per cell.
V – End of capacity battery voltage per cell dependant on battery type as follows:
min
NiCd – 1,10 V;
NiMh – 1,10 V;
Pb – 1,80 V.
Where the controlgear cut off voltage is above these voltages, the cut off voltage becomes
V .
min
Measurement of EBLF shall be made at 25 °C, using a lamp of the appropriate type and
having not been lit for 24 h. The first measurements are made at V at 5 s and 60 s after the
application of the d.c. voltage, and then in steady conditions at V .
min
The lowest value of the values measured at 60 s and V or in steady conditions at V shall
1 min
be retained and shall reach at least the declared EBLF.
The value measured at 5 s and V shall reach at least 50 % of declared EBLF.
NOTE 1 Replace 60 s by 0,5 s for ballasts declared for use in luminaires for high-risk task area lighting.
NOTE 2 As declared, EBLF must be reached after 0,5 s, measurements at 5 s are not considered.
NOTE 3 Any test circuit corresponding to that of Figure 1 can be used to make the measurement of EBLF. The
luminous flux of a lamp is usually measured with an integrating photometer. For ratio measurements of luminous
fluxes, a suitable illuminance meter is sufficient as there is a close relationship between luminous flux and
illumination at a fixed point.
NOTE 4 Other methods may apply for determining EBLF, in particular methods which permanently record the
luminous flux of the lamp associated to the ballast under test.

21 Changeover operation
Changeover from normal to emergency mode shall occur at not less than 0,6 times rated
supply voltage. It shall not occur at greater than 0,85 times rated supply voltage.
The normal mains supply to the ballast shall be reduced within 0,5 s to 0,6 times rated voltage
after which the emergency lamps shall operate.
The ballast shall be switched off and on 500 times, each cycle consisting of 2 s off and 2 s on
(at 0,85 times the rated supply voltage), throughout these cycles and on completion the
ballast shall operate the emergency lamp when switched into emergency mode operation.
NOTE 1 It may be necessary to ensure that batteries are not fully discharged before completion of this test.
Additional charging periods may be required.
For ballasts with rest mode facility, changeover from rest mode to normal mode shall occur
automatically at not greater than 0,9 times the rated supply voltage. In this case, the switching
test is carried out as above but with the off cycle extended to 3 s minimum, with the rest mode
