6.1.3.2 Ballast
The ballast used shall meet the requirements of IEC 60921, where appropriate. It shall have a
rated voltage equal to the supply voltage, or equal to the lowest value of the supply voltage
range for which the starter is designed.
The rated wattage of the ballast shall be chosen to give the most onerous starting conditions
of the range of lamp types for which the starter is designed. In case of doubt the rated
wattage of the ballast shall correspond to the main lamp type for which the starter is
designed.
Where a starter is designed to operate with different ballast types (e.g. capacitive or
inductive), the tests are made with both types of ballast.
6.1.3.3 Lamps
The lamp shall be of the pre-heated cathode type and, where appropriate, meet the
requirements of IEC 60081. The rated wattage of the lamp shall be equal to the rated wattage
of the ballast used.
For starters of the mechanical type defined in 3.1 the lamp shall normally be of the “with
starter” type. For starters of the electronic type defined in 3.2 the lamp shall normally be of
the "starterless type". Where a choice of lamp of "with starter" or "starterless" type is declared
by the manufacturer, the "with starter" type shall be used.
6.1.4 Starters having a mechanical switching element
6.1.4.1 Speed of operation
a) Current operated starters
A current equal to the minimum pre-heating current prescribed on the relevant lamp data
sheet in IEC 60081 shall be passed through the circuit.
For starters which incorporate a cut-out, the starter shall operate at least once during the
test period of 30 s. For continuously operating starters, the starter shall operate at least
twice during the test period of 30 s.
The test is made with a deactivated lamp or with an equivalent resistance of both
cathodes in series as prescribed on the relevant lamp data sheet in IEC 60081.
b) Voltage operated starters
A voltage of 0,92 times the rated voltage of the ballast shall be applied to the circuit.
For starters which incorporate a cut-out, the starter shall operate at least once during the
test period of 30 s.
For continuously operating starters, the starter shall operate at least twice during the test
period of 30 s.
The test is made with a deactivated lamp or with an equivalent resistance of both
cathodes in series as prescribed on the relevant lamp data sheet in IEC 60081.
60927 © IEC:2007 – 11 –
6.1.4.2 Cathode pre-heating
A voltage of 0,92 times the rated voltage of the ballast shall be applied to the circuit.
Starters shall provide sufficient lamp cathode heating. The pre-heating current shall be either
as specified on the relevant lamp data sheet in IEC 60081 or shall be in line with the lamp
manufacturer's requirements relating to current and time.
6.1.4.3 Pulse voltage
The circuit for measuring pulse voltage shall be as shown in Figure 1.
A voltage of 0,92 times the rated voltage of the ballast shall be applied to the circuit for 30 s.
On at least one occasion during this period, the highest pulse voltage (indicated by either of
the two voltmeters) shall be not less than the value mentioned in the column "information for
starter design" of the relevant lamp data sheet of IEC 60081. If the starter is designed for a
range of lamps, care should be taken that the highest voltage value quoted in the sheets for
the lamps within that range should be used.
NOTE As an alternative to the electrostatic voltmeter prescribed in Figure 1, a memory oscilloscope may be used
in the circuit together with a high-voltage probe having the following properties:
− input resistance: ≥100 MΩ,
− iInput capacitance ≤15 pF,
− cut-off frequency ≥1 MHz.
In case of doubt, the measurement with the electrostatic voltmeter is the reference method.
6.1.5 Starters having an electronic switching element
6.1.5.1 General
For explanatory notes and guidance to testing see Annex B.
It may be expected that starters complying with this subclause, when associated with lamps
which comply with IEC 60081 or IEC 60901, will provide satisfactory starting of the lamp at an
air temperature immediately around the lamp between 10 °C and 35 °C and at voltages within
92 % and 106 % of the rated voltage.
For 6.1.5.2, 6.1.5.3 and 6.1.5.4 compliance is checked with:
a) each lamp cathode replaced by a resistance corresponding to the substitution resistor
value prescribed on the relevant lamp data sheet in IEC 60081 or IEC 60901;
b) supply voltages of 0,92 times and 1,06 times the rated voltage of the ballast.
6.1.5.2 Speed of operation
For starters which incorporate a cut-out, the starter shall operate at least once during the test
period of 30 s.
For continuously operating starters, the starter shall operate at least twice during the test
period of 30 s.
– 12 – 60927 © IEC:2007
6.1.5.3 Cathode pre-heating
The starter shall operate so that the minimum total effective heating current shall comply with
the time/current limits specified on the relevant lamp data sheets (see Annex B, Figure B.2).
The absolute minimum pre-heating time shall be at least 0,4 s unless otherwise specified on
the relevant lamp data sheet.
The maximum effective heating current shall not exceed the limits specified on the relevant
lamp data sheet at any time t.
6.1.5.4 Open-circuit voltage
The open-circuit voltage between any pairs of substitution resistors representing a lamp shall
not exceed the maximum values specified on the lamp data sheet, during the pre-heating
period.
After the pre-heating period the voltage shall attain a value, not less than the minimum value
for lamp starting, as specified on the lamp data sheet.
If the current through the substitution resistor, as specified in 6.1.5.3, is interrupted before the
minimum specified voltage for lamp starting has been reached, the voltage rise to minimum
starting voltage shall take place within not more than 0,1 s (see Figure B.3).
If the voltage rise takes more than 0,1 s, the current through the substitution resistor shall not
fall below the absolute minimum value specified on the relevant lamp data sheet (see Figure
B.4).
6.1.6 Non-reoperating level
This subclause applies to starters with mechanical and electronic switching elements.
With a circuit and ballast as previously specified in 6.1.3 but with a lamp connected as in
normal use the following test shall be applied.
6.1.6.1 For voltage operated starters
A supply voltage equal to the rated voltage of the ballast shall be applied to the circuit, and
the lamp shall start and operate normally.
After a period of 30 s lamp operation, the supply voltage shall be reduced within 5 s without
interruption to 85 % of the rated value and held in this condition for 90 s. The lamp shall
remain alight without disturbance from the starter.
6.1.6.2 For current operated starters
A supply voltage equal to the rated voltage of the ballast shall be applied to the circuit, and
the lamp shall start and operate normally.
After a period of 30 s lamp operation the lamp current shall be reduced within 5 s without
interruption to a value which shall be 80 % of the nominal lamp running current as prescribed
on the relevant lamp data sheet given in IEC 60081. This condition is held for 90 s. The lamp
shall remain alight without disturbance from the starter.
60927 © IEC:2007 – 13 –
6.1.7 Maximum pre-heat current (lamp fails to start)
In order to protect lamp cathodes against excessive pre-heating current, if a healthy lamp fails
to start, the following test shall be applied to starters with mechanical and electronic switching
elements.
With the starter connected as for normal operation and with a supply voltage equal to 106 %
of the ballast rated voltage applied to the circuit, the total effective heating current through the
cathodes during the 60 s period immediately after switch-on shall not exceed 115 % of the
nominal running current of the lamps, as prescribed on the relevant lamp data sheets given in
IEC 60081 and IEC 60901.
For this test a deactivated lamp or two separate lamp ends with real cathodes shall be used.
6.1.8 Interruption of starter function
If a manufacturer or responsible vendor declares that the starter has an additional cut-out to
disconnect the starter from the circuit the following test shall be applied.
With the supply voltage equal to the rated voltage of the ballast and with a deactivated
cathode lamp or two separate lamp ends with real cathodes, in the place of the lamp, the
additional cut-out shall operate within 5 min from the application of the supply voltage to the
circuit.
6.2 Endurance test
6.2.1 Test quantity
The test quantity shall consist of three starters which have passed the test of 6.1.
6.2.2 Test conditions
For this test the starters are connected as in normal use, operated at the maximum case
temperature t and associated with a lamp of the highest wattage rating for which the starter
c
is intended together with an appropriate ballast. The ballast shall conform with the
requirements of Annex A. The test voltage shall be equal to the rated voltage of the ballast.
In the event of the lamp failing during this test, arrangements shall be made for its immediate
replacement.
6.2.3 Starters replaceable without tools
The test duration shall be 6 000 cycles, each of 4 min. During each cycle, the voltage shall be

7 Performance requirements for ignitors
This clause specifies performance requirements for ignitors used with low pressure sodium
vapour lamps, high pressure sodium vapour lamps and metal halide lamps, and shall be used
in conjunction with the corresponding publications for these lamps and their ballasts (see
IEC 60192, IEC 60662, IEC 61347-2-9, IEC 60923 and IEC 61167).
7.1 Starting test
7.1.1 Test quantity
The test is made on two ignitors that have not been submitted to any other test.
7.1.2 Test conditions
In this test the ignitors are connected as in normal use.
Ignitors are tested in combination with lamps and ballasts for which the ignitor is intended. For
ignitors intended for more than one lamp type or lamp wattage ratings it may be necessary to
make the test for each lamp type of each wattage rating.
The ballast used shall meet the requirements of the relevant IEC publication and be
compatible with the lamp type or wattage to be started by the ignitor.
7.1.3 Conditions of acceptance
The type complies with the requirements in this clause when both ignitors comply with the
tests specified in 7.1.4 to 7.1.7.
– 16 – 60927 © IEC:2007
If one ignitor fails any test, another two ignitors shall be tested and both shall comply.
7.1.4 Switching speed
The test is made without a lamp
A voltage of 0,92 times the rated supply voltage is applied to the circuit.
During a period of 30 s the starting operation shall take place at least once.
7.1.5 Pulse voltage
To measure the pulse voltage the ignitor is connected in accordance with 7.1.2 but without
lamp, using the circuit shown in Figure 1.
Within the rated temperature range (if any) and with a maximum load capacitance of 1 000 pF
(unless otherwise declared by the manufacturer) and at 0,92 times the rated supply voltage,
the pulse voltage available at the lamp (generated by ignitor or ignitor-ballast combination)
shall be not less than the value declared by the manufacturer.
NOTE As an alternative to the electrostatic voltmeter prescribed in Figure 1, a memory oscilloscope may be used
in the circuit together with a high-voltage probe having the following properties:
− input resistance: ≥100 MΩ,
− input capacitance ≤15 pF,
− bandwidth ≥50 MHz.
In case of doubt, the measurement with the electrostatic voltmeter is the reference method.
7.1.6 Repetition rate, pulse position, width and height of starting pulse for triggered
ignitors
Details are under consideration.
The test is made aided by an oscilloscope and a high-voltage probe. Properties required for
this combination are:
− input resistance 100 MΩ,
− input capacitance 5 pF,
− bandwidth 50 MHz.
7.1.7 Ignition energy for non-triggered ignitors
The ignition energy of non-triggered ignitors shall be measured in the circuit of Figure 2.
Required values are under consideration.
For ignitors for low-pressure sodium lamps both the circuit and values are under
consideration.
7.2 Non-reoperating level
Ignitors shall not operate after the lamp has started.
Two ignitors complying with the test of Clause 7 shall be subjected to the following test.
60927 © IEC:2007 – 17 –
A lamp compatible with the ignitor is connected as in normal use, started and operated until
stabilized.
For ignitors whose function depends on the lamp voltage the supply voltage is reduced
continuously down to 85 % of the rated supply voltage without breaking the supply circuit.
The current flowing through the ignitor circuit after 1 min shall not exceed the rated lamp
current (for ballast protection) and there shall be no disturbance of the lamp function.
For ignitors whose function depends on the lamp current, the lamp current is reduced
continuously down to 80 % of the rated lamp current without breaking the supply circuit.
The current flowing through the ignitor circuit after 1 min shall not exceed the rated lamp
current (for ballast protection) and there shall be no disturbance of the lamp function.
This test is not made if, according to the manufacturer, the ignitor, in addition to the starting
function, performs other functions necessary for the appropriate operation of the lamp.
However, in case of a defective lamp, the current flowing through the ignitor circuit after 1 min
shall not exceed the rated lamp current.
7.3 Endurance test
7.3.1 Test quantity
The test quantity shall consist of two ignitors that have passed the tests of 7.1 and 7.2, as
appropriate, and two additional ignitors for the test as specified in the third paragraph of
7.3.2.
7.3.2 Test conditions
In this test the two ignitors are connected as in normal use, each associated with an
appropriate ballast. The test voltage shall correspond to 1,06 times the rated supply voltage
of the ballast. The ignitors are operated in conformity with their marking at the maximum case
temperature t and without lamp. In doing so, the live connections of one of the ignitors are
c
loaded by the maximum allowable load capacitance, whilst the connections of the other
ignitors are left unloaded.
The ballast used in the life test shall comply with the requirements specified in Annex A.
Ballasts that fail during the endurance test are replaced.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

1 Scope
This International Standard specifies performance requirements for starting devices (starters
and ignitors) for tubular fluorescent and other discharge lamps for use on a.c. supplies up to
1 000 V at 50 Hz or 60 Hz, which produce starting pulses not greater than 5 kV.
This standard is used in conjunction with IEC 61347-1 and IEC 61347-2-1.
NOTE 1 All glow starters for fluorescent and other discharge lamps including thermal relay/cut-outs will be
included in IEC 60155.
NOTE 2 There are regional standards regarding the regulation of EMC requirements for end-products like
luminaires and independent control gear. In a luminaire, the control gear is dominant in this respect. Control gear,
together with other components, should comply with these standards.

– 8 – 60927 IEC:2007
+A1:2013
4 General requirements for tests
4.1 Ambient conditions, test quantity and sequence of tests
Only requirements for type tests are included.
Unless otherwise specified, the tests shall be made at an ambient temperature between 10 °C
and 30 °C.
The tests shall be carried out in the order of the clauses of this standard.
The following numbers of samples shall be submitted:
– six samples of starters as defined in 3.1 and 3.2;
– four samples of ignitors (where appropriate, together with those circuit components which
are necessary to carry out the tests).
4.2 Supply voltage
The total harmonic content of the supply voltage shall not exceed 3 %, the harmonic content
being defined as the root-mean-square (r.m.s.) summation of the individual harmonic
components, using the fundamental as 100 %.
Care shall be taken that this applies under all conditions that occur during the measurement.
NOTE This implies that the source of supply will have sufficient power and that the supply circuit has sufficiently
low impedance at supply frequency and impulse frequency compared with the ballast impedance. The correct
impedance at impulse frequency can be obtained by connecting a 2 µF (approximately) capacitor in parallel
with the source.
4.3 Corresponding safety requirements
All starting devices specified in this standard shall meet the requirements of IEC 61347-2-1.
4.4 Immunity
All starting devices specified in this standard shall meet the requirements of IEC 61547.
NOTE The requirements for starting devices are under consideration in IEC 61547.
4.5 Relation to lamp standards
Attention is drawn to lamp performance standards which contain “Information for ignitor
design”. This information should be followed for proper lamp operation. However, this
standard does not require the testing of lamp performance as part of the type test approval for
ignitors.
5 Marking
The marking requirements of IEC 61347-2-1 shall apply, together with the following, to be
either clearly marked on the starting device or made available in the manufacturer’s
catalogue, or the like.
60927 IEC:2007 – 9 –

6 Performance requirements for starters (other than glow starters) for
fluorescent lamps
This clause specifies performance requirements for starters other than glow starters, used
with tubular fluorescent lamps with pre-heated cathodes, and their associated ballasts (see
IEC 60081 and IEC 60921, where appropriate).
6.1 Starting test
6.1.1 Starting test quantity
The starting test quantity consists of six new starters which have not been subjected to the
tests specified in IEC 61347-2-1.
6.1.2 Conditions of acceptance
The type is considered as satisfying the requirements of this subclause if all six starters
comply with the appropriate tests specified in 6.1.4 to 6.1.8. If one failure occurs, a further six
starters shall be selected and tested and all these shall comply. If more than one failure
occurs the starter is deemed not to satisfy the requirements of this clause.
6.1.3 Conditions of test
6.1.3.1 Circuit
The starter is tested in the circuit declared by the manufacturer.
A starting aid complying with the requirements of Table 1 shall be used unless otherwise
indicated on the starter or in the manufacturer’s literature.
In case of doubt a choice shall be made by mutual agreement between the testing authority
and the manufacturer.
