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 promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. 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. The 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 the 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 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 National
Committees 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. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated 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.
International Standard IEC 60081 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This consolidated version of IEC 60081 is based on the fifth edition (1997) [documents
34A/759/FDIS and 34A/778/RVD], its amendment 1 (2000) [documents 34A/896/FDIS and
34A/907/RVD] and its amendment 2 (2003) [documents 34A/1020/FDIS and 34A/1028/RVD].
It bears the edition number 5.2.
The committee has decided that the contents of the base publication, its amendment 1 and its
amendment 2 will remain unchanged until 2004. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

60081 IEC:1997 – A-2 –
Annex A
(normative)
Method of test for starting characteristics
A.1 General
Tests shall be made in a draught-free atmosphere at an ambient temperature of between 20 °C
and 27 °C and a relative humidity of 65 % maximum.
Metallic parts and wires in the vicinity of the lamp, except starting aids when required, shall be
avoided as far as possible.
Immediately prior to the starting test the lamps shall be kept inoperative and in an ambient
temperature of between 20 °C and 27 °C and a relative humidity of 65 % maximum for a period
of at least 24 h.
A.2 Lamps having preheated cathodes for operation on a.c. mains frequencies
with the use of a starter
A.2.1 Test circuit
Lamps shall be tested with a 50 Hz or 60 Hz supply in the circuit shown in figure A.1.
A.2.2 Ballast
The ballast used shall be of the inductive type, unless specified otherwise on the relevant lamp
data sheet, and shall comply with the requirements of IEC 60921. It shall be rated as specified
on the relevant lamp data sheet. Where a capacitive circuit is specified, additionally the
capacitor used shall comply with the requirements of IEC 61049.
When the ballast, at its rated voltage, is associated with a test lamp, the lamp shall dissipate a
power which does not differ from its rated value by more than 4 %. A test lamp is a lamp whose
voltage at lamp terminals does not deviate by more than 2 % from its rated value, when
operated with its reference ballast.
The preheating current, when measured at 90 % of rated ballast voltage, shall be between 1,1
and 1,2 times the rated lamp current. To obtain a value of the preheating current within this
range, it may be necessary either to make a special selection from among commercial ballasts
or else to design and manufacture a ballast for this specific purpose. In some cases, it may be
possible to bring the preheating current down to be within this range by adding resistance in
series with the starter.
NOTE – In some cases the ballast may include an autotransformer to increase (or reduce) the voltage to the proper
value for the starting and operation of the lamp. Ballasts incorporating step-up transformers are particularly likely to
be used in countries where 120 V or 100 V power systems predominate.
60081 Amend. 2 © IEC:2003 – A-4 –
A.2.3 Starter
The type of glow starter to be used shall comply with the requirements of IEC 60155, and
shall in any case be subject to agreement with the lamp manufacturer or responsible vendor.
A.2.4 Test voltage
The test voltage applied to the circuit shall be as specified on the relevant lamp data sheet.
A.3 Lamps having preheated cathodes for operation on a.c. mains frequencies
without the use of a starter (starterless)
A.3.1 Test circuit
Lamps shall be tested with a 50 Hz or 60 Hz supply in the circuit shown in figure A.2.
A.3.2 Ballast
The ballast used shall be of the inductive type, and shall comply with the requirements of
IEC 60921. It shall be rated as specified on the relevant lamp data sheet.
When the ballast, at its rated voltage, is associated with a test lamp, the lamp shall dissipate
a power which does not differ from its rated value by more than 4 %. A test lamp is a lamp
whose voltage at lamp terminals does not deviate by more than 2 % from its rated value,
when operated with its reference ballast.
NOTE 1 In some cases the ballast may include an autotransformer to increase (or reduce) the voltage to the
proper value for starting and operation of the lamp. Ballasts incorporating transformers are particularly likely to be
used in countries where 100 V, 120 V, 200 V, 277 V or 347 V power systems predominate.
NOTE 2 The earthing of the circuit as shown in figure A.2 may make it necessary to supply it through an isolating
transformer.
A.3.3 Starting aid
The starting aid, a metal plate, shall be connected to earth potential together with one lamp
cathode. Its length shall be not less than that of the lamp under test and it shall be 25 mm
wide for 16 mm diameter lamps and 40 mm wide for 26 mm to 38 mm diameter lamps. The
distance between the surface of the lamp and the starting aid shall be as specified on the
relevant lamp data sheet.
The manufacturer or responsible vendor shall specify whether or not the lamps require an
external starting aid, and whether one cathode shall be connected to earth potential. For
lamps not requiring a separate starting aid, the metal plate shall be removed.
A.3.4 Test voltages
The voltage of the heating circuit to be applied to the cathode terminals and the open circuit
voltage at the lamp terminals for the starting test shall be as specified on the relevant lamp
data sheet.
NOTE The voltages specified for the starting test are chosen primarily to secure reproducibility of test results, and
are not necessarily applicable to the design of ballasts.
60081 IEC:1997 – A-8 –
A.5.2 Ballast
The non-inductive ballast resistor shall be so adjusted that the high frequency lamp current is
equal to the value as specified on the relevant lamp data sheet.
A.5.3 Starting aid
For lamps with preheated cathodes, the starting aid, a metal plate, shall be connected to earth
potential together with one lamp cathode. Its length shall be not less than that of the lamp
under test, and it shall be 25 mm wide for 16 mm diameter lamps, and 40 mm wide for 26 mm
to 38 mm diameter lamps. The distance between the surface of the lamp and the starting aid
shall be as specified on the relevant lamp data sheet.
The manufacturer or resposible vendor shall specify whether or not the lamps require an
external starting aid, and whether one cathode shall be connected to earth potential. For lamps
not requiring a separate starting aid, the metal plate shall be removed.
A.5.4 Test voltage and current
For lamps with preheated cathodes, the cathode heating supplies shall be adjusted to supply a
preheat current as specified on the relevant lamp data sheet. During the preheat time,
specified on the relevant lamp data sheet, switch S shall be kept open and switches S closed.
1 2
After this period of time, switches S shall be opened simultaneously as switch S is closed.
2 1
The open circuit voltage applied to the circuit shall be as specified on the relevant lamp data
sheet.
60081 IEC:1997 – B-8 –
The centre value of the cathode voltage for low-resistance cathodes is 3,6 V, and it is
convenient to use a regular 6,3 V filament transformer operated at a reduced primary voltage
so that an output of 3,6 V is obtained.
B.2.4 Calibration of cathode heating transformer
Each cathode transformer (or pair of transformers) shall be individually calibrated to determine
the power loss that will exist during normal operation.
This power will vary with the current to be supplied to the particular type of cathode involved.
These loss values, however, need to be determined only once for a given transformer for each
cathode type. The appropriate transformer loss can then be applied to the measurement of the
various types of lamps.
It is convenient to obtain a "voltage calibration" on each transformer. This involves determining
the primary voltage that must be set in order to obtain the required secondary output voltage.
This calibration, although not entirely essential, makes it possible to use primary voltage
settings in all routine work, thus avoiding the need for constant use of the more fragile low-
range thermocouple voltmeters.
In making the calibration, each secondary winding of the transformer should be connected to a
substitution resistor, having the electrical characteristics specified for the particular cathode
type involved. The primary voltage should be adjusted so that the average of the two secondary
voltages is 3,6 V, and the value of the primary voltage should then be recorded. It is essential
that this calibration is repeated for any other cathode type with which the transformer is used.
E /R loss considered together) shall also be
The power loss in the transformer (core loss and
determined for each load condition. With the primary voltage again set so as to give the
specified voltage of 3,6 V across the substitution resistors, the power input shall be read.
(Since the total wattage to be read is likely to be below 10 W, a low-range wattmeter shall be
used). The loss in the transformer may be calculated as the wattage input reading, minus the
instrument corrections, and also minus the power absorbed by the substitution resistors. This
power in the resistors can be calculated as E /R for each of the windings.
The transformer loss is assumed to be constant for all lamps having the same cathode
resistance, and no allowance is necessary for the slight differences resulting from variations in
actual cathodes.
B.3 Cathode characteristics of lamps having preheated cathodes for operation
on starterless circuits
B.3.1 Test circuit
Cathode resistance shall be measured using a suitable d.c. supply or a 50 Hz or 60 Hz a.c.
supply.
B.3.2 Lamps for operation on a.c. mains frequencies
The voltage at the cathode terminals shall be adjusted to the value of the test voltage given on
the relevant lamp data sheet, and the current shall be measured. From these, after deduction
of the consumption of the voltmeter, the cathode resistance shall be determined.
60081 Amend. 2 © IEC:2003 – B-10 –
B.3.3 Lamps for operation on high frequency
The current flowing through the cathode shall be adjusted to the value of the test current
given on the relevant lamp data sheet, and the supply voltage shall be measured. From these,
after deduction of the voltage across the ammeter, the cathode resistance shall be
determined.
B.4 Measurement procedure for the determination of the maximum luminous flux of
16 mm tube diameter lamps for operation on high frequency
B.4.1 General
This procedure applies when a requirement is given on the lamp data sheet concerning
maximum luminous flux at ambient temperatures other than 25 °C. The tolerance of the
ambient temperature at which the maximum luminous flux shall be obtained is given on the
relevant lamp data sheet.
B.4.2 Conditioning of the lamp
The lamp shall be aged for 100 h in a vertical position. During ageing the cold chamber shall
be at the lowest point. The position of the cold chamber shall be indicated by the
manufacturer.
Measurements shall be made after a sufficient period of stabilization of the lamp. After
stabilization, any lamp movement shall be carried out carefully with no vibration or shock and
with the cold chamber always at the lowest point.
B.4.3 Absolute measurement
Apart from the conditioning procedure, the rated luminous flux measurement is performed as
described in clause B.1.
B.4.4 Relative measurement
The maximum luminous flux measurement is based on a relative measurement of either
luminous flux or of illuminance versus ambient temperature.
B.4.4.1 Equipment for relative measurement and operating position
A thermally insulated container of suitable shape (for example a rectangular box) and size
shall be used.
Alternative: an un-insulated container, located inside a temperature-controlled chamber, i.e.
“double-layer” (which allows air to circulate around the container without the presence of a
draught on the lamp).
The internal temperature of the container shall be controllable within the temperature range of
20 °C to 45 °C, so that the temperature at which maximum luminous flux occurs is included.
The inner surface of the container shall be coated with a suitable material dependant upon the
applied detection method (the recorded signal shall be proportional to luminous flux or
illuminance in the temperature range of measurement).
The lamp shall be mounted in the centre of the container in a horizontal position. The distance
between the lamp and the walls of the container shall be at least 200 mm in all directions.
NOTE If it can be shown that distances less than 200 mm give the same result, then smaller distances can be
used.
60081 Amend. 2 © IEC:2003 – B-12 –
Electrical connection to the lamp pins shall be made using a method which minimizes heat
sinking of the lamp (for example using lamp holders with low thermal capacitance or
connecting directly to the lamp pins).
The temperature within the container shall be measured at a position which is level with the
centre of the lamp in the vertical plane, equidistant between the lamp ends in the horizontal
plane and equidistant between the lamp and container wall.
NOTE In practice, an additional measurement point at the control point of the lamp is advised (in the vicinity of
the cold chamber which determines the mercury vapour pressure).
A suitable light detector (thermally insulated and/or stabilized) shall be mounted outside the
container or inside the container if its temperature dependence is known. For luminous flux
measurements, the light detector shall receive light via reflection only with the direct light
being blocked by a baffle. For illuminance measurements, the light detector shall receive light
directly from the lamp.
The recorded signal from the detector shall be proportional to the luminous flux or the
illuminance in the temperature range of measurement.
B.4.4.2 Execution of relative measurements
The lamp shall be tested in the appropriate circuit given in figure B.3. The reference ballast
shall be positioned outside the container. After starting, the supply voltage of the reference
ballast shall be held constant throughout the measurement.
There shall be no artificial air movement in the container. However, air ventilation is needed in
order to obtain an isotropic temperature distribution.
The measurement shall start at the lowest temperature of interest. It is recommended that the
rate of temperature rise in the range of 20 °C to 45 °C be less than 5 K/h.
NOTE This is required in order to achieve reproducible results with minimum measurement uncertainties.
Measurements of the luminous flux or illuminance and the ambient temperature shall be made
in suitable temperature/time intervals throughout the period of measurement.
B.4.5 Translation into absolute values
Combining the absolute measurement with the relative measurements will provide a complete
luminous flux versus ambient temperature profile for the lamp.
