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
This second edition of IEC 61347-2-3, published in conjunction with IEC 61347-1, represents
an review of the first edition of IEC 61347-2-3. 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 intended to be self-contained and, therefore, do not
include references to each other. However, for the case of emergency lighting lamp control
gear, some cross-referencing has been necessary.
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 control gear covered by this particular part
of IEC 61347-2.

15.5 Isolation of input terminals of controllable electronic control gear
For controllable electronic control gear, the control input shall be isolated from the mains
circuit by insulation at least equal to basic insulation.
NOTE This requirement does not apply to those control gear where control signals are injected via the supply
terminals or where the control signals are completely isolated from the ballast by being transmitted remotely from
infra-red or radio wave transmitters.
If SELV is to be used, then double or reinforced insulation is required.
16 Abnormal conditions
16.1 Abnormal conditions for a.c. and d.c. control gears
The control gear shall not impair safety when operated under abnormal conditions at any
voltage between 90 % and 110 % of the rated supply voltage.
– 12 – 61347-2-3 © IEC:2011
Compliance is checked by the following test.
Each of the following conditions shall be applied with the control gear operating according to
the manufacturer's instructions (including a heat sink, if specified) for 1 h:
a) the lamp or one of the lamps is not inserted;
b) the lamp does not start because one of the cathodes is broken;
c) the lamp does not start although the cathode circuits are intact (de-activated lamp);
d) the lamp operates, but one of the cathodes is de-activated or broken (rectifying effect);
e) short circuit of the starter switch, if any.
For the test simulating operation with a de-activated lamp, a resistor is connected in place of
each lamp cathode. The resistor value is derived from the value of the nominal running
current of the lamp prescribed in the relevant lamp data sheet of IEC 60081 and IEC 60901
and substituted in the following equation:
11,0
R = Ω
2,1 × I
n
where
I is the rated lamp current of the lamp.
n
For lamps not covered by IEC 60081 and IEC 60901, the values declared by the lamp
manufacturer shall be used.
When testing electronic ballasts for the rectifying effect, the circuit shown in Figure 1 is used.
The anode of the rectifier is connected to the midpoints of appropriate equivalent resistors;
the cathode of the rectifier is connected to the short circuited lamp electrode. The direction of
the rectifying effect is chosen so as to give the most unfavourable conditions. If necessary,
the lamp is started using a suitable device.
During and at the end of the tests specified under items a) to e), the control gear shall show
no defect impairing safety nor shall any smoke be produced.
16.2 Additional abnormal conditions for d.c. supplied electronic control gear
If the d.c. supplied electronic control gear declared by the manufacturer as a protected control
gear against the reversal polarity of the supply voltage, then the following test is applied:
The d.c. supplied electronic control gear shall be connected for 1 h with the reversal supply
voltage at the maximum value of the rated voltage with the maximum lamp power declared by
the manufacturer.
During and at the end of the test the electronic control gear shall operate the lamp(s) normally
without any defects.
17 Behaviour of the control gear at end of lamp life
17.1 End of lamp life effects
At the end of lamp life, the control gear shall behave in such a way that no overheating of
lamp cap(s) occurs at any voltage between 90 % and 110 % of the rated supply voltage.

For the test simulating end of lamp life effects, three tests are described:
a) asymmetric pulse test (described in 17.2);
b) asymmetric power dissipation test (described in 17.3);
c) open filament test (described in 17.4).
Any of the three tests may be used to qualify electronic control gear. The control gear
manufacturer shall determine which of the three tests will be used to test a given control gear
based on the design of that particular control gear circuit. The chosen test method shall be
indicated in the control gear manufacturer’s literature.
NOTE 1 Checking control gear against their capability to cope with the partial rectifying effect is recommended by
IEC 61195, Annex E, and IEC 61199, Annex H.
NOTE 2 In Japan, only the requirements of 17.1 b) are applied for electronic control gear.
Lamps used in the ballast test circuits shall be new lamps seasoned for 100 h.
17.2 Asymmetric pulse test
The ballast shall have adequate protection to prevent lamp cap overheating at the end of the
lamp life cycle. Compliance is checked by the following test.
The following values of maximum cathode power P apply:
max
– for 13 mm (T4) lamps, P = 5,0 W;
max
– for 16 mm (T5) lamps, P = 7,5 W.
max
(Other diameters are under study.)
Test procedure:
Refer to the schematic diagram in Figure 1.
If only one connection per electrode is available at the control gear and/or lamp, T1 shall be
removed and then the control gear shall be connected to J2 and the lamp to J4. The control
gear manufacturer should be asked which of the output terminals has to be connected to J4
and, in case two output terminals per electrode exist, whether they can be short-circuited or
be bridged with a resistor.
(1) Close switches S1 and S4, and set switch S2 to position A.
(2) Turn on the control gear under test and allow lamp(s) to warm up for 5 min.
(3) Close S3, open S1, and wait for 15 s. Open S4 and wait for 15 s.
(4) Measure the sum of the average power dissipated in the power resistors, R1A to R1C
and R2A and R2B, and the Zener diodes, D5 to D8.
NOTE The power should be measured as the average value of the product of the voltage between
terminals J5 and J6 times the current flowing from J8 to J7. The voltage should be measured with a
differential voltage probe, and the current should be measured with a d.c. current probe. A digital
oscilloscope can be used for the multiplication and averaging functions. If the control gear operates in a
cycling mode, the averaging interval should be set to cover an integer number of cycles. (Each cycle is
typically greater than 1 s.) The sampling rate and number of samples included in the calculations should be
sufficient to avoid aliasing errors.
The power dissipation shall be below P .
max
If the power dissipation is greater than P , the control gear has failed and the test is
max
discontinued.
(5) Close S1 and S4.
(6) Set S2 to position B.
– 14 – 61347-2-3 © IEC:2011
(7) Repeat steps (2), (3) and (4).
The control gear shall pass both position “A” and position “B” tests.
(8) For multi-lamp control gear, repeat steps (1) to (7) for each lamp position.
A multi-lamp control gear shall pass the tests for each lamp position.
(9) For control gear that operate multiple lamp types (e.g. 26 W, 32 W, 42 W), each lamp
type specified shall be tested. Repeat steps (1) to (8) for each lamp type.

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.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 61347-2-3 edition 2.1 contains the second edition (2011-05) [documents 34C/955/FDIS and
34C/968/RVD], its corrigendum 1 (2011-09) and its amendment 1 (2016-07) [documents
34C/1206/FDIS and 34C/1241/RVD].

supplied electronic control gear for fluorescent lamps.
NOTE In this standard, the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type.
– Explanatory matter: in smaller roman type.
A list of all parts of the IEC 61347 series, published under the general title: Lamp control
gear, can be found on the IEC website.
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This second edition of IEC 61347-2-3, published in conjunction with IEC 61347-1, represents
an review of the first edition of IEC 61347-2-3. 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 intended to be self-contained and, therefore, do not
include references to each other. However, for the case of emergency lighting lamp control
gear, some cross-referencing has been necessary.
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 control gear covered by this particular part
of IEC 61347-2.

16 Abnormal conditions
16.1 Abnormal conditions for a.c. and d.c. control gears
The control gear shall not impair safety when operated under abnormal conditions at any
voltage between 90 % and 110 % of the rated supply voltage.
Compliance is checked by the following test.
Each of the following conditions shall be applied with the control gear operating according to
the manufacturer's instructions (including a heat sink, if specified) for 1 h:
a) the lamp or one of the lamps is not inserted;
b) the lamp does not start because one of the cathodes is broken;
c) the lamp does not start although the cathode circuits are intact (de-activated lamp);
d) the lamp operates, but one of the cathodes is de-activated or broken (rectifying effect);
e) short circuit of the starter switch, if any.
For the test simulating operation with a de-activated lamp, a resistor is connected in place of
each lamp cathode. The resistor value is derived from the value of the nominal running
current of the lamp prescribed in the relevant lamp data sheet of IEC 60081 and IEC 60901
and substituted in the following equation:
11,0
R= Ω
2,1 × I
n
where
I is the rated lamp current of the lamp.
n
For lamps not covered by IEC 60081 and IEC 60901, the values declared by the lamp
manufacturer shall be used.
When testing electronic ballasts for the rectifying effect, the circuit shown in Figure 1 is used.
The anode of the rectifier is connected to the midpoints of appropriate equivalent resistors;
the cathode of the rectifier is connected to the short circuited lamp electrode. The direction of
the rectifying effect is chosen so as to give the most unfavourable conditions. If necessary,
the lamp is started using a suitable device.
During and at the end of the tests specified under items a) to e), the control gear shall show
no defect impairing safety nor shall any smoke be produced.
16.2 Additional abnormal conditions for d.c. supplied electronic control gear
If the d.c. supplied electronic control gear declared by the manufacturer as a protected control
gear against the reversal polarity of the supply voltage, then the following test is applied:
The d.c. supplied electronic control gear shall be connected for 1 h with the reversal supply
voltage at the maximum value of the rated voltage with the maximum lamp power declared by
the manufacturer.
During and at the end of the test the electronic control gear shall operate the lamp(s) normally
without any defects.

17 Behaviour of the control gear at end of lamp life
17.1 End of lamp life effects
At the end of lamp life, the control gear shall behave in such a way that no overheating of
lamp cap(s) occurs at any voltage between 90 % and 110 % of the rated supply voltage.
For the test simulating end of lamp life effects, three tests are described:
a) asymmetric pulse test (described in 17.2);
b) asymmetric power dissipation test (described in 17.3);
c) open filament test (described in 17.4).
Any of the three tests may be used to qualify electronic control gear. The control gear
manufacturer shall determine which of the three tests will be used to test a given control gear
based on the design of that particular control gear circuit. The chosen test method shall be
indicated in the control gear manufacturer’s literature.
NOTE 1 Checking control gear against their capability to cope with the partial rectifying effect is recommended by
IEC 61195, Annex E, and IEC 61199, Annex H.
NOTE 2 In Japan, only the requirements of 17.1 b) are applied for electronic control gear.
Lamps used in the ballast test circuits shall be new lamps seasoned for 100 h.
17.2 Asymmetric pulse test
The ballast controlgear shall have adequate protection to prevent lamp cap overheating at the
end of the lamp life cycle. Compliance is checked by the following test. The relevant values of
lamp power, maximum asymmetric power P at the cathodes and the designation of lamp
max
cap shall be taken from Annex E of IEC 60081 and Annex D of IEC 60901 respectively.
The following values of maximum cathode power P apply:
max
– for 13 mm (T4) lamps, P = 5,0 W;
max
– for 16 mm (T5) lamps, P = 7,5 W.
max
(Other diameters are under study.)
NOTE Amendment 6 of IEC 60081 is under preparation. Stage at the time of publication:
IEC CDV 60081 AMD6:2015.
Test procedure:
Refer to the schematic diagram in Figure 1.
If only one connection per electrode is available at the control gear and/or lamp, T1 shall be
removed and then the control gear shall be connected to J2 and the lamp to J4. The control
gear manufacturer should be asked which of the output terminals has to be connected to J4
and, in case two output terminals per electrode exist, whether they can be short-circuited or
be bridged with a resistor.
(1) Close switches S1 and S4, and set switch S2 to position A.
(2) Turn on the control gear under test and allow lamp(s) to warm up for 5 min.
(3) Close S3, open S1, and wait for 15 s. Open S4 and wait for 15 s.
(4) Measure the sum of the average power dissipated in the power resistors, R1A to R1C
and R2A and R2B, and the Zener diodes, D5 to D8.
– 14 – IEC 61347-2-3:2011+AMD1:2016 CSV
© IEC 2016
NOTE The power should be measured as the average value of the product of the voltage between
terminals J5 and J6 times the current flowing from J8 to J7. The voltage should be measured with a
differential voltage probe, and the current should be measured with a d.c. current probe. A digital
oscilloscope can be used for the multiplication and averaging functions. If the control gear operates in a
cycling mode, the averaging interval should be set to cover an integer number of cycles. (Each cycle is
typically greater than 1 s.) The sampling rate and number of samples included in the calculations should be
sufficient to avoid aliasing errors.
The power dissipation shall be below P .
max
If the power dissipation is greater than P , the control gear has failed and the test is
max
discontinued.
(5) Close S1 and S4.
(6) Set S2 to position B.
(7) Repeat steps (2), (3) and (4).
The control gear shall pass both position “A” and position “B” tests.
(8) For multi-lamp control gear, repeat steps (1) to (7) for each lamp position.
A multi-lamp control gear shall pass the tests for each lamp position.
(9) For control gear that operate multiple lamp types (e.g. 26 W, 32 W, 42 W), each lamp
type specified shall be tested. Repeat steps (1) to (8) for each lamp type.

17.3 Asymmetric power test
The controlgear shall have adequate protection to prevent lamp cap overheating at the end of
the lamp life cycle. Compliance is checked by the following test. The relevant values of lamp
power, maximum cathode power P at the cathodes and the designation of lamp cap shall
max
be taken from Annex E of IEC 60081 and Annex D of IEC 60901 respectively.
The following values of maximum cathode power P apply:
max
– for 13 mm (T4) lamps, P = 5,0 W;
max

Test procedure:
Refer to the schematic diagram in Figure 2.
(1) Set switch S1 to position A.
(2) Set resistance of resistor R1 to 0 (zero) Ω.
(3) Start lamp(s) by turning on power to controlgear under test and allow lamp(s) to warm

R1 equals the test wattage power value of 10 W for a T4 lamp or 15 W for a T5 lamp
twice the asymmetric power P in Annex E of IEC 60081 and Annex D of IEC 60901
max
respectively. If the controlgear limits the power in R1 to a value less than the test
wattage power, set R1 at the value which produces the maximum wattage. If the
controlgear switches off before reaching the test wattage power, continue with (5). If the
controlgear does not switch off and limits the power in R1 to a value less than the test
wattage power, set R1 at the value which produces the maximum wattage power.
