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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 61347-2-12:2005+AMD1:2010 CSV. A vertical bar
appears in the margin wherever a change has been made. Additions are in green text,

INTRODUCTION
This standard, and the parts which make up IEC 61347-1, 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 references 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.
The technical requirements in this document compared to IEC 61347-2-12:2005 and
IEC 61347-2-12:2005/AMD1:2010 are essentially unchanged. Nevertheless, a new edition of
this document could not be avoided, as without the introduction of dated references to
IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, the fourth edition of IEC 61347-1:—
would have been implicitly applicable due to the undated nature of the references to
IEC 61347-1 in IEC 61347-2-12:2005 and IEC 61347-2-12:2005/AMD1:2010.
This document, in referring to any of the clauses of IEC 61347-1:2015 and
IEC 61347-1:2015/AMD1:2017, specifies the extent to which such a clause is applicable.
Additional requirements are also included, as necessary.

into account however, the maximum ignition voltage specified in the relevant lamp data sheets.
If not otherwise stated on the relevant lamp data sheets, For electronic ballasts controlgear with
ignition voltages over 5 kV, the maximum value shall not exceed 1,3 x U 130 % of the ignition
p
voltage declared by the manufacturer when operated at the rated supply voltage and with a load
capacitance of 20 pF, if not otherwise stated on the relevant lamp data sheets.
NOTE In some countries, the ignition voltage is restricted to 4 kV.
16.3 Ignition time cut-out
Electronic ballasts controlgear equipped with cut-outs shall be of such a construction that, in
the case of non-igniting lamps, the cut-out interrupts at least the production of the ignition
voltage.
After the cut-out has interrupted the circuit, the generation of the ignition voltage is allowed
either after disconnecting and reconnecting the ballast controlgear to the supply or by control
signal.
Electronic ballasts controlgear with ignition voltages over 5 kV shall be provided with a cut-out
for igniting. Time to cut-out is limited:
– for ignition voltages 5 kV to 10 kV to 60 s,
– for ignition voltages > 10 kV a) to 3 s, or
b) to 30 s, if declared in the manufacturer's literature.
The cut-out time of 60 s for an ignition voltage from 5 kV to 10 kV can be extended, depending
on the lamp type, up to a period of 20 min within which the combined intervals of ignition
attempts add up to 60 s, provided it is evident for the maintenance service staff that the
controlgear is still trying to ignite.
17 Abnormal conditions
The ballast controlgear shall not impair safety when operated under abnormal conditions at any
voltage between 90 % and 110 % of the rated supply voltage or range of rated supply voltage
declared by the manufacturer.
Compliance is checked by the following test.

– 14 – IEC 61347-2-12:2024 RLV © IEC 2024
Each of the following conditions shall be applied with the ballast controlgear operating to the
manufacturer's instructions (including a heat sink, if specified) for 1 h:
a) the lamp is not inserted or does not ignite;
b) the burner leaks;
c) the lamp operates, but rectifies.
Condition a) is tested with an open output.
Condition b) is tested with the circuit in Figure 1 (see below).

Condition c) is tested with the circuit in Figure 2 (see below).
The lamp in the circuit is replaced by the test circuit shown in Figure 2.
Both current directions have to shall be checked: ballast controlgear terminal 1 with circuit wire
1 and ballast controlgear terminal 1 with circuit wire 2.
The controlgear is stabilized at the ambient temperature of the draught-proof enclosure between
10 °C and 30 °C.
The resistor resistance R has to shall be chosen such that the electrical operating conditions
are the same as with the lamp. An appropriate resistance value can be found by the following
calculation:
R = U / P
1 lamp magn lamp magn
where
U is the lamp voltage in magnetic ballast controlgear operation;

P is the lamp wattage power in magnetic ballast controlgear operation;

U and P are taken from the relevant lamp standard sheet as long as electronic
lamp magn lamp magn
lamp operation data are not available from the lamp manufacturer.
NOTE R changes as a function of the lamp type for the same lamp wattage power.
The test is commenced by varying the resistor resistance R to adjust the current to a value
equal to twice the normal lamp current; when this is reached, no further adjustment of R is
made.
If after 1 h the internal protection of the controlgear has not operated, the resistor resistance
R shall be adjusted to increase the current up to three times maximum the normal lamp current.
If the internal protection of the controlgear operates before the current reaches a value equal
to twice the normal lamp current, the controlgear is loaded, varying the resistance R , by a
current equal to 0,95 times the value of the lowest current which causes the protective device
to operate. The lowest current causing the protective device to operate is determined by initially
operating the controlgear at the normal lamp current and gradually increasing the output current
in steps of 2 % (each step is maintained until a steady condition is achieved) until the protective
device operates. However, the current shall not be adjusted above a value of three times the
normal lamp current.
The steady state condition is considered to have been reached when the difference between
two consecutive readings of temperature rise over the ambient taken at a half hour interval has
not exceeded 1 K.

Precautions to be observed when measuring
with spherical spark sphere-gaps
A.1 General
Because many electronic ballasts do not have outputs where one pole is at earth potential, the
direct application of IEC 60052 cannot apply.
In all cases the following clauses shall be observed together with those requirements of
IEC 60052 which are applicable.
Clause A.2, Clause A.3, Clause A.4 and Clause A.5 shall be observed together with those
requirements of IEC 60052:2002 which are applicable.
NOTE IEC 60052 cannot be applied directly because many electronic controlgear do not have outputs where one
pole is at earth potential.
I.1A.2 Spherical spark gap
The sphere-gap (spherical spark gap) shall be greater than the anticipated breakdown distance
and shall be progressively reduced until breakdown occurs (i.e. too small a gap opening up to
a non-sparking distance is not a valid method of determining the correct voltage value).
I.2A.3 Breakdown gap distance
The breakdown gap distance shall be recorded and the 50 % peak voltage value determined
from IEC 60052:2002, Table 2.
I.3A.4 Duty cycle of the electronic ballast controlgear
The duty cycle of the electronic ballast controlgear shall be observed to ensure that overheating/
or failure of the components is not induced.
I.4A.5 End of test
All safety precautions shall be observed and all voltages shall be discharged at the end of the
test.

CONTROLGEAR FOR ELECTRIC LIGHT SOURCES – SAFETY –

Part 2-12: Particular requirements – DC or AC supplied electronic
controlgear for discharge lamps (excluding fluorescent lamps)

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 61347-2-12 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC
technical committee 34: Lighting. It is an International Standard.
This second edition cancels and replaces the first edition published in 2005 and
Amendment 1:2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) introduction of dated references where appropriate;
b) clarification of sample item numbers;
c) addition of new information requirements (items v), w) and x) of IEC 61347-1:2015, 7.1 and
IEC 61347-1:2015/AMD1:2017, 7.1).

The text of this International Standard is based on the following documents:

INTRODUCTION
The technical requirements in this document compared to IEC 61347-2-12:2005 and
IEC 61347-2-12:2005/AMD1:2010 are essentially unchanged. Nevertheless, a new edition of
this document could not be avoided, as without the introduction of dated references to
IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, the fourth edition of IEC 61347-1:—
would have been implicitly applicable due to the undated nature of the references to
IEC 61347-1 in IEC 61347-2-12:2005 and IEC 61347-2-12:2005/AMD1:2010.
This document, in referring to any of the clauses of IEC 61347-1:2015 and
IEC 61347-1:2015/AMD1:2017, specifies the extent to which such a clause is applicable.
Additional requirements are also included, as necessary.

14 Fault conditions
IEC 61347-1:2015, Clause 14 and IEC 61347-1:2015/AMD1:2017, Clause 14 apply.

15 Protection of associated components
The output voltages measured shall be those between all output terminals and any output
terminal and earth.
Under normal and abnormal operating conditions none of these output voltages shall exceed
the working voltage as declared by the manufacturer. The ignition phase being defined by
switch-on or by the beginning of the ignition process up to the time limit as given in Clause 16
is exempted.
Under normal and abnormal (see Clause 17) conditions, if a time limitation is declared for
ignition, it shall not be exceeded.
16 Ignition voltage
16.1 Instruments
Measurements are made by oscilloscope or electrostatic voltmeters for ignition voltages up to
100 kV.
NOTE 1 A typical electrostatic voltmeter is specified in IEC 61347-2-1:2024, Figure 1.
Many electronic controlgear cannot have grounded outputs. In case a differential probe has to
be used, it may have an impedance greater than 1 MΩ at up to 10 kHz. For higher frequencies
f the probe shall have an impedance Z greater than a 15 pF capacitance (C) based on the
equation
Z = 1/(2π f C)
The cut-off frequency should be ≥ 30 MHz at –3 dB.
NOTE 2 Above 15 kV a sphere-gap can be used, using the procedure based on that given in IEC 60052:2002. See
in addition Annex A of this document. In case of doubt, the measurement with the electrostatic voltmeter is the
reference method.
16.2 Ignition voltage limits
The maximum value of the ignition voltage shall not exceed 5 kV when operated at the rated
voltage and with a load capacitance of 20 pF (including the capacitance of the probe), or using
the circuit shown in IEC 61347-2-1:2024, Figure 1 for either positive or negative pulses, taking
into account however, the maximum ignition voltage specified in the relevant lamp data sheets.
For electronic controlgear with ignition voltages over 5 kV, the maximum value shall not exceed
130 % of the ignition voltage declared by the manufacturer when operated at the rated supply
voltage and with a load capacitance of 20 pF, if not otherwise stated on the relevant lamp data
sheets.
NOTE In some countries, the ignition voltage is restricted to 4 kV.
16.3 Ignition time cut-out
Electronic controlgear equipped with cut-outs shall be of such a construction that, in the case
of non-igniting lamps, the cut-out interrupts at least the production of the ignition voltage.
After the cut-out has interrupted the circuit, the generation of the ignition voltage is allowed
either after disconnecting and reconnecting the controlgear to the supply or by control signal.

– 12 – IEC 61347-2-12:2024 © IEC 2024
Electronic controlgear with ignition voltages over 5 kV shall be provided with a cut-out for
igniting. Time to cut-out is limited:
– for ignition voltages 5 kV to 10 kV to 60 s,
– for ignition voltages > 10 kV a) to 3 s, or
b) to 30 s, if declared in the manufacturer's literature.

The cut-out time of 60 s for an ignition voltage from 5 kV to 10 kV can be extended, depending
on the lamp type, up to a period of 20 min within which the combined intervals of ignition
attempts add up to 60 s, provided it is evident for the maintenance service staff that the
controlgear is still trying to ignite.
17 Abnormal conditions
The controlgear shall not impair safety when operated under abnormal conditions at any voltage
between 90 % and 110 % of the rated supply voltage or range of rated supply voltage declared
by the manufacturer.
Compliance is checked by the following test.
Each of the following conditions shall be applied with the controlgear operating to the
manufacturer's instructions (including a heat sink, if specified) for 1 h:
a) the lamp is not inserted or does not ignite;
b) the burner leaks;
c) the lamp operates, but rectifies.
Condition a) is tested with an open output.
Condition b) is tested with the circuit in Figure 1 (see below).

Condition c) is tested with the circuit in Figure 2 (see below).
The lamp in the circuit is replaced by the test circuit shown in Figure 2.

Both current directions shall be checked: controlgear terminal 1 with circuit wire 1 and
controlgear terminal 1 with circuit wire 2.
The controlgear is stabilized at the ambient temperature of the draught-proof enclosure between
10 °C and 30 °C.
The resistance R shall be chosen such that the electrical operating conditions are the same as
with the lamp. An appropriate resistance value can be found by the following calculation:
R = U / P
1 lamp magn lamp magn
where
U is the lamp voltage in magnetic controlgear operation;
lamp magn
P is the lamp power in magnetic controlgear operation;
lamp magn
U and P are taken from the relevant lamp standard sheet as long as electronic
lamp magn lamp magn
lamp operation data are not available from the lamp manufacturer.
NOTE R changes as a function of the lamp type for the same lamp power.
The test is commenced by varying the resistance R to adjust the current to a value equal to
twice the normal lamp current; when this is reached, no further adjustment of R is made.
If after 1 h the internal protection of the controlgear has not operated, the resistance R shall
be adjusted to increase the current up to three times maximum the normal lamp current.
If the internal protection of the controlgear operates before the current reaches a value equal
to twice the normal lamp current, the controlgear is loaded, varying the resistance R , by a
current equal to 0,95 times the value of the lowest current which causes the protective device
to operate. The lowest current causing the protective device to operate is determined by initially
operating the controlgear at the normal lamp current and gradually increasing the output current
in steps of 2 % (each step is maintained until a steady condition is achieved) until the protective
device operates. However, the current shall not be adjusted above a value of three times the
normal lamp current.
The steady state condition is considered to have been reached when the difference between
two consecutive readings of temperature rise over the ambient taken at a half hour interval has
not exceeded 1 K.

Annex A
(informative)
Precautions to be observed when measuring
with sphere-gaps
A.1 General
Clause A.2, Clause A.3, Clause A.4 and Clause A.5 shall be observed together with those
requirements of IEC 60052:2002 which are applicable.
NOTE IEC 60052 cannot be applied directly because many electronic controlgear do not have outputs where one
pole is at earth potential.
A.2 Spherical spark gap
The sphere-gap (spherical spark gap) shall be greater than the anticipated breakdown distance
and shall be progressively reduced until breakdown occurs (i.e. too small a gap opening up to
a non-sparking distance is not a valid method of determining the correct voltage value).
A.3 Breakdown gap distance
The breakdown gap distance shall be recorded and the 50 % peak voltage value determined
from IEC 60052:2002, Table 2.
A.4 Duty cycle of the electronic controlgear
The duty cycle of the electronic controlgear shall be observed to ensure that overheating or
failure of the components is not induced.
A.5 End of test
All safety precautions shall be observed and all voltages shall be discharged at the end of the
test.
Annex B
(informative)
Schedule of more onerous requirements
Products found compliant with the previous edition of this document do not necessarily require
complete requalification for demonstrating compliance with this document. Depending on the
nature of the changes introduced, partial retesting or even no retesting may be appropriate, as
the case may be.
The following list contains all changes that impose more onerous requirements with respect to
the previous edition, i.e. IEC 61347-2-12:2005 and IEC 61347-2-12:2005/AMD1:2010, which
should therefore be considered for requalification purposes:
– 7.1.2 (information to be provided): items v), w) and x).
NOTE Being new information requirements, the requirements do not involve testing, but only an update of
documentation.
