FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6)  Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

3 Definitions
For the purpose of this part of IEC 61347, the definitions given in clause 3 of IEC 61347-1
apply, together with the following:
3.1
starting device
apparatus which provides, by itself or in combination with other components in the circuit, the
appropriate electrical conditions needed to start a discharge type of lamp
3.2
starter
starting device, usually for fluorescent lamps, which provides for the necessary preheating of
the electrodes and may, in combination with the series impedance of the ballast, cause a surgein the voltage applied to the lamp
NOTE  The starter element that releases the starting voltage pulse may be either triggered, for example, phase-
angle synchronized, or non-triggered.
3.3
starting device with operating time limitation
starting device which prevents prolonged attempts to start lamps which refuse to start, for
example, lamps with deactivated electrodes
NOTE  Prevention of starting attempts means that in the case of starters, the starting-current circuit is switched off
and/or the current in the starting circuit is limited to a value equal to or smaller than the rated lamp current.
In the case of ignitors, prevention of starting attempts means that pulse generation has ceased, or voltage pulses
are significantly reduced in amplitude.
3.4
peak voltage
Up
highest value of the voltage pulses generated by an ignitor at the output terminals
3.5
short-circuit power  (of a voltage source)
quotient of the square of the voltage produced at its output terminals (in open-circuit
conditions) and the internal impedance of the source (as seen from the same terminals)
3.6
spherical spark gap
two metal spheres of the same nominal diameter arranged at a specified distance and used
under specified conditions for the measurement of peak voltages in excess of 15 kV
4 General requirements
The requirements of clause 4 of IEC 61347-1 apply.61347-2-1  IEC:2000 – 15 –
5 General notes on tests
The requirements of clause 5 of IEC 61347-1 apply, together with the following additional
requirements:
5.1 Starting devices for use with lamps having different electrical characteristics
Starting devices intended for use with lamps having different electrical characteristics are
tested with the lamp which gives the most unfavourable conditions.
5.2 Number of specimens
The following number of specimens shall be submitted for testing:
–one unit for the tests of clauses 6 to 12 and 15 to 22;
–one unit for the tests of clause 14 (additional units or components, where necessary, may
be required in consultation with the manufacturer).
6 Classification
The requirements of clause 6 of IEC 61347-1 apply, together with the following additionalrequirements:
Output voltage
Starting devices are classified according to output voltage categories as follows:
–up to and including 5 kV;
–greater than 5 kV, and up to and including 10 kV;
–greater than 10 kV, and up to and including 100 kV.
7 Marking

8 Protection against accidental contact with live parts
The requirements of clause 10 of IEC 61347-1 apply.
9 Terminals
The requirements of clause 8 of IEC 61347-1 apply.
10 Provisions for earthing
The requirements of clause 9 of IEC 61347-1 apply.
11 Moisture resistance and insulation
The requirements of clause 11 of IEC 61347-1 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 to ensure
constant circulation of the air within and, in general, to use a cabinet which is thermallyinsulated.
With double or reinforced insulation, the resistance shall be not less than 7 M Ω.
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 draughtand having similar conditions to those in the humidity cabinet.
12 Electric strength
The requirements of clause 12 of IEC 61347-1 apply, together with the following additionalrequirement:
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.61347-2-1  IEC:2000 – 19 –
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 for 1 min.
13 Thermal endurance test for windings
The requirements of clause 13 of IEC 61347-1 are not applicable and a separate test is under
consideration.
14 Fault conditions
The requirements of clause 14 of IEC 61347-1 apply, together with the following additionalrequirements:
14.6  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
tw-value at abnormal conditions. For starters having external dimensions as specified in
IEC 60155, this requirement is met if the current in the lamp circuit does not exceed the
maximum pre-heat current value as specified in IEC 60081 and IEC 60901 for a period longerthan 5 min.
14.7  Independent starting devices shall not exceed the temperature values for abnormal
operation given in 15.2. This requirement is regarded as complied with when, for preheated
lamp electrodes, the preheating current has not increased by more than 5 % above the valuewith the starting device 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-circuitvalue for a period longer than 5 min.
This requirement is regarded as being complied with when the mechanical cut-out meets the
relevant conditions of IEC 60255-8.
15 Heating of independent starting devices
Independent starting devices shall not reach excessive temperatures during normal operationand abnormal operation.
NOTE  Built-in starting devices are checked together with the luminaire in accordance with IEC 60598-1.
Compliance is checked by the following tests:
Normal conditions are working conditions in which one or more of the following situations
apply:
a) lamps are operating normally;
b) rated current flows through the starting device;61347-2-1  IEC:2000 – 21 –
c) the starting device has been connected to a voltage source, for example, the mains voltage
or the lamp voltage arising during normal operation;
d) combination of b) and c).
Independent starting devices are mounted in a test corner consisting of three dull black painted
wood/wood fibre 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 annex F.
15.1 Normal operation
The starting devices are connected as for normal use with appropriate lamps.
When the lamp is in stable operation, the lamp current is set for the rated value by modifying
the voltage applied. In this condition, the starting device and lamps are operated until they
reach steady temperature.
The temperatures of the components shall not exceed the values specified in tables 12.1 and
12.2 of IEC 60598-1.
The ballast employed shall meet the requirements of the relevant IEC standard and be
compatible with the lamp type to be started by the starting device.
15.2 Abnormal operation
Starters are connected as for normal use with appropriate lamps. The test is made with lamps
having deactivated cathodes or substitution resistors specified in IEC 60081 and IEC 60901 on
the lamp data sheets. A lamp of the highest wattage rating for which the starter is suitable and
an appropriate ballast shall be used.
Ignitors are connected as for appropriate use without lamps.
In the case of abnormal conditions, the ignitors are operated at 110 % of the rated voltage until
they reach the steady temperature, or, for ignitors with operating time limitation, until they cut
out at or before the required time limit. After this, the temperature of the components is
determined. Temperatures shall not exceed the values specified in table 12.3 of IEC 60598-1.
Upon completion of these tests, and after cooling down, the starting device shall comply with
the following conditions:
a) the starting device marking shall still be legible;
b) the starting device shall withstand without damage an electric strength test according to
clause 12 of this standard, the test voltage, however, being reduced to 75 % of the values
given in table 1 of IEC 61347-1, but not less than 500 V.61347-2-1  IEC:2000 – 23 –
16 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 circuitshown in figure 1. However, the maximum pulse voltage specified in the relevant lamp datasheet 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 × 
Up declared by the manufacturer
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 thosegiven in IEC 60052, and taking note of annex J of this standard.
NOTE  As an alternative to the electrostatic voltmeter prescribed in figure 1, a memory oscilloscope can be used in
the circuit together with a high-voltage probe having the following properties:
–input resistance /G95 100 M Ω;
–input capacitance /G94 15 pF;
–cut-off frequency /G95 1 MHz.
In case of doubt, the measurement with the electrostatic voltmeter is the reference method to use.
17 Mechanical strength
17.1  Replaceable starting devices and accessible components of starting devices which can
be replaced without tools shall have sufficient mechanical strength.
– Starting devices and components up to 100 g and all starters having external dimensions
specified in IEC 60155 shall be subjected to the tumbling barrel test in accordance with
I.2. Each sample shall withstand 20 falls without incurring any damage which might affect
safety.
– Starting devices and components over 100 g shall be subjected to the spring hammer
test in accordance with I.1. The impact energy and spring compression of the testing
apparatus shall be 0,35 Nm and 17 mm, respectively.
After the test, the sample shall show no damage likely to impair safety.
17.2  Replaceable starting devices and accessible components of starting devices which can
be replaced without tools, but which are subject to a turning moment during normal insertion,
shall withstand a torque test of 0,6 Nm about the axes.
The torque is applied at the canister top. The contact pins are clamped tight and the torque is
gradually increased from zero to the value required.
After the test, the sample shall show no damage likely to impair safety.
18 Construction
The requirements of clause 15 of IEC 61347-1 apply, together with the following additional
requirements:61347-2-1  IEC:2000 – 25 –
18.1  All replaceable starting devices and accessible components of starting devices which
can be replaced without the aid of a tool shall have double insulation or reinforced insulation to
be compatible with the insulation requirements of all classes of equipment, including class II.
18.2  Starting devices equipped with cut-outs shall be so constructed that, in the case of non-
igniting lamps, the cut-out interrupts the starting-current circuit and/or the production of the
starting voltage.
An alternative to a cut-out can be a device limiting the starting current and the production of
starting voltage to such an extent that no current greater than 10 % of the rated lamp currentflows through the lamp. Further components in the overall lamp-current circuit are notsubjected to loads higher than the rated lamp current.
Compliance is checked by reference to clauses 14 or 15.
Ignitors with pulse voltages over 10 kV shall be provided with a device for time limitation of thestarting operation. This device shall, in case of non-ignition of lamps, interrupt the generationof starting pulses within 3 s. After the time limitation device has interrupted the circuit,generation of starting pulses is only allowed after disconnection and reconnection of theignitors to the supply.
Ignitors with pulse voltages over 5 kV and up to 10 kV shall be provided with a time-limiting
device which shall interrupt the generation of pulses within 60 s. After the time-limiting devicehas interrupted the circuit, generation of starting pulses is only allowed after disconnection andreconnection of the ignitors to the supply.
Compliance is checked by inspection and by the test of clause 15.
18.3  Starters which are interchangeable with glow starters in accordance with IEC 60155 shall
contain means for radio interference suppression, the effect of which is equivalent to that of the
radio interference suppression capacitor prescribed in 7.12 of IEC 60155.

Replaceable starting devices and accessible components over 100 g mass are tested as
follows.
Blows are applied to the part under test by means of the spring-operated impact test apparatus
specified in IEC 60068-2-75.
An impact test apparatus is used which is adjusted so that when the test apparatus is held in a
horizontal position, the kinetic energy of the striking element just before the impact has thevalue specified in table E.1 of IEC 60068-2-75.
NOTE  In order to avoid frequent calibration, it is recommended that a separate test apparatus be used for each

The blows are applied by positioning the release cone against the starting device in a direction
perpendicular to the surface, at the point to be tested.
The starting device is rigidly supported, cable entries being left open, knock-outs opened and
cover fixing and similar screws tightened with a torque equal to two-thirds of that specified inclause 19.
Three blows are applied to every point that is likely to be weak, paying special regard to
insulating material enclosing live parts and to bushings of insulating material, if any. After thesetests, the starting device shall show no damage within the meaning of this standard.
Damage to paint and small dents which do not influence creepage distances or clearances are
neglected. There shall not be any decrease in the resistance to the ingress of moisture.
I.2  Replaceable starting devices and accessible components up to 100 g
Replaceable starting devices and accessible components up to 100 g mass are tested asfollows.

Annex J
(normative)
Precautions to be observed when measuring with sphere-gaps
Because many ignitors do not have outputs where one pole is at earth potential, the direct
application of IEC 60052 cannot apply. However, the following subclauses shall be observed,together with those requirements of IEC 60052 which are applicable.
J.1  Sphere gap
The sphere gap shall be greater than the anticipated breakdown distance and shall beprogressively reduced until breakdown occurs (i.e. too small a gap opening up to non-sparkingdistance is not a valid method of determining the correct voltage value).
J.2  Breakdown gap distance
The breakdown gap distance shall be recorded and the 50 % peak voltage value determinedfrom table II in IEC 60052.
J.3  Duty cycle of the ignitor
The duty cycle of the ignitor shall be observed to ensure that overheating/failure of thecomponents does not occur.
J.4  End of test
All safety precautions shall be observed and all voltages shall be discharged at the end of thetest.61347-2-1  IEC:2000 – 39 –
