Part 2-1: Particular requirements – Starting devices
(other than glow starters)
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

INTRODUCTION
This first edition of IEC 61347-2-1, published in conjunction with IEC 61347-1, represents an
editorial review of IEC 60926. 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 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 61347-2-1:2000,
IEC 61347-2-1:2000/AMD1:2005 and IEC 61347-2-1:2000/AMD2:2013 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 61347-2-1:2000,
IEC 61347-2-1:2000/AMD1:2005 and IEC 61347-2-1:2000/AMD2:2013.
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.

– an indication of the time limitation, if this is provided by the starting device;
– the catalogue reference of the ballast which may be associated with the starting device, if
the ballast design governs the magnitude of the pulse voltage;
– special conditions relating to the use of the starting device.
7.2 Durability and legibility
IEC 61347-1:2015, 7.2 applies.
8 Terminals
IEC 61347-1:2015, Clause 8 and IEC 61347-1:2015/AMD1:2017, Clause 8 apply.
9 Provisions for Earthing
IEC 61347-1:2015, Clause 9 applies.
10 Protection against accidental contact with live parts
IEC 61347-1:2015, Clause 10 and IEC 61347-1:2015/AMD1:2017, Clause 10 apply.
11 Moisture resistance and insulation
IEC 61347-1:2015, Clause 11 and IEC 61347-1:2015/AMD1:2017, Clause 11 apply, together
with the following:
– Electric components, enclosures and other parts which can be removed without the aid of a
tool are removed and subjected, if necessary, to the humidity treatment with the main part.
– In order to achieve the specified conditions within the cabinet, it is necessary recommended
to ensure constant circulation of the air within and, in general, to use a cabinet which is
thermally insulated.
– With double or reinforced insulation, the resistance shall be not less than 7 MΩ.
– Care should be taken to avoid the moisture content of the devices at the end of the moisture
treatment changing appreciably before the measurement of the insulation resistance.

To achieve this, it is recommended that the insulation resistance be measured while the
devices are still kept in the humidity cabinet or in an adjacent room protected against
draught and having similar conditions to those in the humidity cabinet.
12 Electric strength
IEC 61347-1:2015, Clause 12 applies, together with the following:
Pulsing test
For starting devices which incorporate a high-voltage winding, compliance is checked by the
following pulsing test. The starting device is operated at 110 % rated supply voltage without a
lamp load until 50 pulses have occurred, switching the supply on and off if necessary.
NOTE High-voltage winding denotes a winding incorporated in the starting device which produces the necessary
voltage to start the lamp.
During the test, there shall be
a) no visible or audible disruptive discharge (indication of failure of insulation under electrical
stress);
b) no sparkover or flashover;
c) no collapse or reduction of the front or the tail of the impulse voltage waveshape when
observed on an oscilloscope.
For starting devices without high-voltage winding, compliance is checked by an electric strength
test as given in IEC 61347-1:2015, Clause 12.
13 Thermal endurance test for windings of ballasts
There are no requirements.
NOTE The requirements of IEC 61347-1:2015, Clause 13 are not applicable and a separate test is under
consideration.
14 Fault conditions
IEC 61347-1:2015, Clause 14 and IEC 61347-1:2015/AMD1:2017, Clause 14 apply, together
with the following:
– The current in the lamp circuit shall not be increased by a fault in the starting device to such
an extent that the ballast becomes overheated, i.e. the winding temperature exceeds the
t value at abnormal conditions. For starters having external dimensions as specified in
w
IEC 60155:1993, IEC 60155:1993/AMD1:1995 and IEC 60155:1993/AMD2:2006, this
requirement is met if the current in the lamp circuit does not exceed the maximum preheat
current value as specified in IEC 60081 and IEC 60901 for a period longer than 5 min.
– Independent starting devices shall not exceed the temperature values for abnormal
operations given in 16.3.3. This requirement is regarded as complied with when, for
preheated lamp electrodes, the preheating current does not increase above its rated value
by more than 5 % when the starting device is short-circuited. Mechanical cut-outs in starting
devices shall be bridged if, with preheated lamp electrodes at 110 % of rated voltage, the
current through the ballast is more than 105 % of the short-circuit value for a period longer
than 5 min.
– 14 – IEC 61347-2-1:2024 RLV © IEC 2024
This requirement is regarded as being complied with when the mechanical cut-out meets
the relevant conditions of IEC 60255-8:1990 .
15 Pulse voltage of ignitors
The maximum value of the pulse voltage, of either positive or negative pulses, shall not exceed
5 kV when operated at the rated voltage and with a load capacitance of 20 pF, using the circuit
shown in Figure 1. However, the maximum pulse voltage specified in the relevant lamp data
sheet shall be taken into account.
If not otherwise stated on the relevant lamp data sheets, for ignitors with pulses over 5 kV, the
maximum value of the pulse voltage shall not exceed 1,3 × U declared by the manufacturer
p
when operated at the rated supply voltage and with a load capacitance of 20 pF.
Measurements are made by oscilloscope or static voltmeter for peak pulses up to 100 kV. Above
15 kV, a spherical spark gap can be employed, using the procedure based on those given in
IEC 60052, and taking note of annex J of this standard.

the width of the starting device. Furthermore, the blocks shall be positioned with the extreme
end of the starting device aligned with the outer vertical sides of the block.
The controlgear employed for the components shall meet the requirements of the relevant IEC
standard and be compatible with the lamp type to be started by the starting device.
The whole test circuit (controlgear, built-in starting device and the lamp(s)) is connected to the
supply voltage. When the lamp is in stable operation, the lamp current is set for rated value by
modifying the voltage applied. The ambient temperature of the test enclosure is adjusted to
reach t on the starting device. In this condition, the starting devices and lamp are operated
c
until they reach steady temperature.

Compliance is checked by the temperature measurement. The measured value shall not exceed
the limits specified in IEC 60598-1:2020, Table 12.1 and Table 12.2.
16.2.3 Normal operation of independent starting devices

procedure.
Independent starting devices are connected as for normal use with appropriate lamps.
Independent starting devices are mounted in a test corner consisting of three dull black painted
laminated wood boards 15 mm to 25 mm thick and arranged so as to resemble two walls and
the ceiling of a room. The starting device is secured to the ceiling as close as possible to the
walls, the ceiling extending at least 250 mm beyond the other sides of the starting device. This
assembly is positioned as far as possible from the five internal surfaces of the enclosure.
The tests are carried out in a draught-proof room or enclosure as specified in
IEC 61347-1:2015, Annex F. The ambient temperature within the draught-proof enclosure shall
be within 5 °C of the t rating and should preferably be the same as the t rating.
