LAMP CONTROLGEAR –
Part 2-9: Particular requirements for electromagnetic
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) 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 61347-2-9 has been prepared by subcommittee 34C: Auxiliaries
for lamps, of IEC technical committee 34: Lamps and related equipment.

13 Thermal endurance test for windings
The requirements of Clause 13 of IEC 61347-1:2007 apply.
14 Electromagnetic controlgear heating
14.1 General
Electromagnetic controlgear, or their mounting surfaces, shall not attain a temperature which
would impair safety.
Compliance is checked by the tests of 14.1 to 14.3 and H.12 of IEC 61347-1:2007.
14.2 Test requirements
When the electromagnetic controlgear is tested in accordance with the requirements of 14.2
and 14.3, the temperature shall not exceed the appropriate values given in Table 2 for the test
under normal and abnormal conditions.
61347-2-9 © IEC:2012 – 11 –
Before the test, the following shall be checked and measured:
a) the electromagnetic controlgear shall start and operate the lamp(s) normally;
b) the resistance of each winding shall be measured, if required, at the ambient temperature.
After this heating test, the electromagnetic controlgear shall be allowed to cool to room
temperature and then shall comply with the following conditions:
c) the electromagnetic controlgear marking shall still be legible;
d) the electromagnetic controlgear shall withstand without damage a dielectric strength test
according to Clause 12, the test voltage, however, being reduced to 75 % of the value
given in Table 1 of IEC 61347-1:2007, but not less than 500 V.
14.3 Normal operating condition
For the test under normal conditions, electromagnetic controlgear are operated with
appropriate lamps which are placed in such a way that the heat generated does not contribute
to the heating of the electromagnetic controlgear. Lamps are deemed to be appropriate if they
pass, under the prescribed test conditions, a current within the tolerances of the current a
reference lamp would pass.
The winding temperature t with declared temperature rise ∆t of the winding, the temperature
w
of capacitors and other parts listed in Table 2 if used with the electromagnetic controlgear
shall not exceed the values according to Table 2.
Electromagnetic controlgear windings with temperature rise ∆t are tested under normal
conditions with the following details:
– 100 % of rated voltage and at rated frequency,
– until steady temperature is attained.
Capacitors and parts listed in Table 2 are tested under normal conditions with the following
details:
– 106 % of rated voltage and at rated frequency,
– until steady temperature is attained.
14.4 Abnormal operating condition
The abnormal operating conditions test is only required for electromagnetic controlgear for
some metal halide lamps and some high pressure sodium vapour lamps which, according to
the lamp safety standard IEC 62035, can lead to electromagnetic controlgear overloading.
For electromagnetic controlgear designed in accordance to Annex B of IEC 61347-1:2007,
Amendment 1:2010 the abnormal test is not required.
The abnormal operating tests for electromagnetic controlgear are only required in the built-in
situation in the luminaires and they are a part of the luminaires verifications. The tests for
abnormal circuit conditions are described in IEC 60598-1, Annex C.
Table 3 and Table 4 represent the context between the constants S and the limiting
temperature for different winding temperatures t . Table 3 stands for the endurance test
w
duration of 30 days and Table 4 for the endurance test duration of 60 days.

If materials or manufacturing methods are used other than those indicated in the table; they shall not be operated
at temperatures higher than those which are proved to be permissible for those materials.
The temperatures in this table shall not be exceeded when the electromagnetic controlgear is operated at its
maximum declared ambient temperature. The values in the table are based on an ambient temperature of 25 °C.
a
The measurement of the temperature rise of the windings under normal conditions at 100 % of rated voltage,
i.e. verification of a declared value so as to provide information for luminaire design, is non-mandatory and its
measurement is only performed when marked on the electromagnetic controlgear or otherwise claimed in the
catalogue.
b
This measurement is only mandatory for circuits which may produce abnormal conditions. The declared limiting
temperature of the windings under abnormal conditions (if any) is not measured but should correspond to a
number of days at least equal to two-thirds of the theoretical endurance test period so as to provide information
for luminaire design (see Table 3).

The temperature of thermoplastic material, other than that used for the insulation of the wiring, which provides
protection against contact with live parts or supporting such parts, is also measured. Values thus obtained
serve to establish the conditions of the test of 18.1 of IEC 61347-1:2007.

15 High-voltage impulse testing
15.1 General
Electromagnetic controlgear for metal halide and those for high-pressure sodium vapour
lamps, which are intended for circuits in which high-voltage impulses occur on the
electromagnetic controlgear, shall be subjected to the test of either 15.2 or 15.3 below.
Electromagnetic controlgear designed for operating in a circuit with a starting device external
to the lamp shall be subjected to the test of 15.2.
Electromagnetic controlgear designed for operating lamps with an internal starting device
shall be subjected to the test of 15.3. The manufacturer shall state which test his product has
undergone.
15.2 Test for electromagnetic controlgear operating with lamp with external starting
devices
With a load capacitance of 20 pF, the six electromagnetic controlgear mentioned in Clause 5
are operated with the ignitor and the impulse voltage measured. The ignitor is then removed
and the dielectric strength of components subjected to impulse voltage is then tested as
follows.
The electromagnetic controlgear is operated with another similar ignitor at 1,1 times the rated
voltage, without load capacitance and without a lamp, for a period of 30 days. Should the
ignitor break down before the 30 days have elapsed, it shall be replaced as often as
breakdown occurs until the test duration of 30 days has been completed.
Electromagnetic controlgear which are marked for exclusive use with an ignitor having a time-
delay device (see 7.2), are subjected to the same test, but for a period consisting of
250 on/off cycles, keeping an off period of at least 2 min.
Following this test, the voltage test of Clause 12 is carried out whereby the individual
terminations, with the exception of the earthing conductor, are connected with each other. In
doing so, no sparkover or flashover shall occur. The impulse voltage is then measured again
with the original ignitor and the same load capacitance of 20 pF. Deviation from the original
value shall not be more than 10 %.
15.3 Test for electromagnetic controlgear operating with lamps with internal starting
devices
Using the six samples in 5.1, three samples are subjected to the moisture resistance and
dielectric strength test specified in Clauses 11 and 12, respectively.
The remaining three samples are heated in an oven until they attain the t rating temperature
w
marked on the electromagnetic controlgear.
Immediately following these pre-conditioning tests, all six samples shall withstand the high-
voltage impulse test.
The electromagnetic controlgear under test, together with a variable resistor and a suitable
circuit-breaker with a pull-in time (bounce time excluded) between 3 ms and 15 ms (for
example, a vacuum switch type H16 or VR 312/412), is connected by a d.c. supply in such a
way that, by adjusting the current and operating the circuit-breaker, voltage pulses will be
induced in the electromagnetic controlgear. The current is then adjusted slowly, increasing so
that the peak voltage marked on the electromagnetic controlgear is reached. The
measurement of the voltage pulses is made directly at the electromagnetic controlgear
terminations and in accordance with Figure 1.
61347-2-9 © IEC:2012 – 15 –
If electronic circuit-breakers with a very short pull-in time are used, care should be taken
against producing a highly induced pulse voltage.
The value of the d.c. current at which the starting voltage is reached is noted. The samples
are then operated with this current for 1 h and the current is interrupted during this time, 10
times for 3 s within every minute.
Immediately after the test, all six electromagnetic controlgear shall withstand the moisture
resistance and dielectric strength test specified in Clauses 11 and 12, respectively.
NOTE The use of this test for electromagnetic controlgear other than of the simple reactor type is under
consideration.
