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

INTRODUCTION
There will be and are already LED products in the market which substitute existing lamps,
either as retrofit mains voltage incandescent or self-ballasted fluorescent lamps or as
replacement for tungsten halogen lamps below 50 V.
The present document takes up the supply voltage range from > 50 V up to 250 V. A proposal
for a safety standard for LED lamps with voltages ≤ 50 V may follow in due time.
Future work will also consequently comprise performance standards for all kind of LED lamps,
including minimum photometric requirements for type testing.
Due to the urgent need of establishing this standard, it will be a stand-alone standard for the
time being, not excluding a future relocation as a part of IEC 60968, self-ballasted lamps.

4 General requirements and general test requirements
4.1 The lamps shall be so designed and constructed that in normal use they function reliably
and cause no danger to the user or surroundings.
In general, compliance is checked by carrying out all the tests specified.
4.2 Self-ballasted LED-lamps are non-repairable, factory-sealed units. They shall normally
not be opened for any tests. In the case of doubt based on the inspection of the lamp and the
examination of the circuit diagram, and in agreement with the manufacturer or responsible
vendor, either the output terminals shall be short-circuited or, in agreement with the
manufacturer, lamps specially prepared so that a fault condition can be simulated shall be
submitted for testing (see Clause 13).
4.3 In general, all tests are carried out on each type of lamp or, where a range of similar
lamps is involved, for each wattage in the range or on a representative selection from the
range, as agreed with the manufacturer.
4.4 When the lamp fails safely during one of the tests, it is replaced, provided that no fire,
smoke or flammable gas is produced. Further requirements on failing safe are given in Clause
12.
5 Marking
5.1 Lamps shall be clearly and durably marked with the following mandatory markings:
a) mark of origin (this may take the form of a trademark, the manufacturer’s name or the
name of the responsible vendor);
b) rated voltage or voltage range (marked “V” or “volts”);
c) rated wattage (marked “W” or “watts”);
d) rated frequency (marked in “Hz”).
5.2 In addition, the following information shall be given by the lamp manufacturer on the
lamp or immediate lamp wrapping or container or in installation instructions.
a) Burning position, if restricted, shall be marked with the appropriate symbol. Symbol
examples are shown in Annex B.
b) rated current (marked “A” or “ampere”);
c) “For lamps with a weight significantly higher than that of the lamps for which they are a
replacement, attention should be drawn to the fact that the increased weight may reduce
the mechanical stability of certain luminaires and lampholders and may impair contact
making and lamp retention.”
– 10 – 62560  IEC:2011
d) Special conditions or restrictions which shall be observed for lamp operation, for example
operation in dimming circuits. Where lamps are not suitable for dimming, the following
symbol in Figure 1 may be used:

e) For eye protection, see requirements of IEC/TR 62471-2
5.3 Compliance is checked by the following:
Presence and legibility of the marking required in 5.1 – by visual inspection.
The durability of the marking is checked by trying to remove it by rubbing lightly for 15 s with
a piece of cloth soaked with water and, after drying, for a further 15 s with a piece of cloth
soaked with hexane. The marking shall be legible after the test.
Availability of information required in 5.2 – by visual inspection.
6 Interchangeability
6.1 Cap interchangeability
Interchangeability shall be ensured by the use of caps in accordance with IEC 60061-1 and

6.2 Bending moment, axial pull and mass
The value of the bending moment, imparted by the lamp at the lampholder shall not exceed
the value given in Table 2.
The bending moment shall be determined by measuring the weight of the lamp (e. g. by
means of a balance) at the tip of the bulb of the horizontally held lamp and multiplying this
force by the distance between the tip of the bulb and the pivot line. The pivot line shall lie at
the bottom end of the cylindrical part (for Edison and bayonet caps) or at the end of the
contact pins (for pin caps). It shall be supported by an upright held thin metal sheet or a
similar means.
The lamp construction shall withstand externally applied axial pull and bending moment.
For the measurement method, see A.2.1 of IEC 61199.
The mass as given in Table 2 shall not be exceeded.

NOTE 1 For lamps with caps different to those in Table 2, the effect of the bending moment should be regarded
and limited. A measurement method for these lamps with these caps is under consideration.
NOTE 2 It should be taken care that the luminaire surface where the lampholder is fixed to can withstand the
bending moment. For the calculation of this bending moment, the length of the lampholder needs to be taken into
account when measuring the overall length. This should be made sure for the elevated temperature during
operation in order to check the possible softening of the surface material.
7 Protection against accidental contact with live parts
The lamps shall be so constructed that, without any additional enclosure in the form of a
luminaire, no internal metal parts, basic insulated external metal parts or live metal parts of
the lamp cap or of the lamp itself are accessible when the lamp is installed in a lampholder
according to the relevant IEC lampholder data sheet.
Compliance is checked by means of the test finger specified in Figure 2, if necessary, with a
force of 10 N.

Lamps with Edison screw caps shall be so designed that they comply with the requirements
for inaccessibility of live parts for general lighting service (GLS) lamps.
Compliance is checked with the aid of a gauge in accordance with the current edition of
IEC 60061-3, sheet 7006-51A for E27 caps and sheet 7006-55 for E14 caps.
Requirements for lamps with E26 caps are under consideration.
Lamps with B22, B15, GU10 or GZ10 caps are subject to the same requirements as normal
incandescent lamps with this cap.
Requirements for lamps with GX53 caps are under consideration.
External metal parts other than current-carrying metal parts of the cap shall not be or become
live. For testing, any movable conductive material shall be placed in the most onerous
position without using a tool.
Compliance is checked by means of the insulation resistance and electric strength test (see
Clause 8).
8 Insulation resistance and electric strength after humidity treatment
8.1 General
Insulation resistance and electric strength shall be adequate between live parts of the lamp
and accessible parts of the lamp.
8.2 Insulation resistance
The lamp shall be conditioned for 48 h in a cabinet containing air with a relative humidity
between 91 % and 95 %. The temperature of the air is maintained within 1 °C of any
convenient value between 20 °C and 30 °C.
Insulation resistance shall be measured in the humidity cabinet with a DC voltage of
approximately 500 V, 1 min after application of the voltage.
The insulation resistance between live parts of the cap and accessible parts of the lamp
(accessible parts of insulating material are covered with metal foil) shall be not less than
4 MΩ. The requirements of IEC 61347-1, Annex A, shall be complied with.
NOTE The insulation resistance of bayonet caps between shell and contacts is under consideration.
8.3 Electric strength
Immediately after the insulation resistance test, the same parts as specified above shall
withstand a voltage test for 1 min with an AC voltage as follows.
During the test, the supply contacts of the cap are short-circuited. Accessible parts of
insulating material of the cap are covered with metal foil. Initially, no more than half the
voltage prescribed in IEC 60598-1, Table 10.2 for Class II luminaires is applied between the
contacts and the metal foil. It is then gradually raised to the full value.
No flashover or breakdown shall occur during the test. Measurements shall be carried out in
the humidity cabinet.
NOTE The distance between the foil and the live parts is under consideration.

62560  IEC:2011 – 15 –
9 Mechanical strength
9.1 Torsion resistance of unused lamps
The torsion resistance of unused lamps is tested as follows.
The cap shall remain firmly attached to the bulb or that part of the lamp which is used for
screwing the lamp in or out when subjected to the torque levels listed in Table 3 below.
Tests are made according to the description of the relevant lamp standard per lamp type in
IEC 60432-1 and by means of the test holders shown in Figures 3 and 4.

The torque shall not be applied suddenly, but shall be increased continuously from zero to the
specified value.
In the case of un-cemented caps, relative movement between cap and bulb is permitted
provided it does not exceed 10°.
9.2 Torsion resistance of lamps after a defined time of usage
The torsion resistance of used lamps is under consideration.
9.3 Repetition of Clause 8
After the mechanical strength test, the sample shall comply with the requirements of
accessibility (see Clause 8).
10 Cap temperature rise
The surface temperature rise (above ambient) of a lampholder fitted to the lamp shall not be
higher than that of the lamp type which is being replaced by the lamp.
The cap temperature rise Δt of the complete lamp shall not exceed 120 K. The value of
s
Δt corresponds to a 60 W max. incandescent lamp. The operating position and ambient
s
temperature are detailed in IEC 60360.
Measurement shall be carried out at rated voltage. If the lamp is marked with a voltage range,
it shall be measured at the maximum voltage of that range.
11 Resistance to heat
The lamp shall be sufficiently resistant to heat. External parts of insulating material providing
protection against electric shock, and parts of insulating material retaining live parts in
position shall be sufficiently resistant to heat.
Compliance is checked by subjecting the parts to a ball-pressure test by means of the
apparatus shown in Figure 5.

Figure 5 – Ball-pressure test apparatus
(from IEC 60598-1, Figure 10)
The test is made in a heating cabinet at a temperature of (25 ± 5) °C in excess of the
operating temperature of the relevant part according to Clause 10, with a minimum of
125 °C for parts retaining live parts in position and 80 °C (value 80 °C under consideration)

62560  IEC:2011 – 19 –
for other parts. The surface of the part to be tested is placed in the horizontal position and a
steel ball of 5 mm diameter pressed against this surface with a force of 20 N.
The test load and the supporting means are placed within the heating cabinet for a sufficient
time to ensure that they have attained the stabilized testing temperature before the test
commences.
The part to be tested is placed in the heating cabinet, for a period of 10 min, before the test
load is applied.
The surface where the ball presses should not bend, if necessary the surface shall be
supported. For this purpose, if the test cannot be made on the complete specimen, a suitable
part may be cut from it.
The specimen shall be at least 2,5 mm thick, but if such a thickness is not available on the
specimen, then two or more pieces are placed together.
After 1 h, the ball is removed from the specimen, which is then immersed for 10 s in cold
water for cooling down to approximately room temperature. The diameter of the impression is
measured, and shall not exceed 2 mm.
In the event of curved surfaces, the shorter axis is measured if the indent is elliptical.
In case of doubt, the depth of the impression is measured and the diameter calculated using
the formula
Φ= 2 p(5− p)
in which p is the depth of impression.
The test is not made on parts of ceramic material.
12 Resistance to flame and ignition
Parts of insulating material retaining live parts in position and external parts of insulating
material providing protection against electric shock are subjected to the glow-wire test in
accordance with IEC 60695-2-10, IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13,
subject to the following details.
– The test specimen is a complete lamp. It may be necessary to take away parts of the lamp
to perform the test, but care is taken to ensure that the test conditions are not significantly
different from those occurring in normal use.
– The test specimen is mounted on the carriage and pressed against the glow-wire tip with a
force of 1 N, preferably 15 mm, or more, from the upper edge, into the centre of the
surface to be tested. The penetration of the glow-wire into the specimen is mechanically
limited to 7 mm.
If it is not possible to make the test on a specimen as described above because the specimen
is too small, the above test is made on a separate specimen of the same material, 30 mm
square and with a thickness equal to the smallest thickness of the specimen.
– The temperature of the tip of the glow-wire is 650 °C. After 30 s, the specimen is
withdrawn from contact with the glow-wire tip.
The glow-wire temperature and heating current are constant for 1 min prior to commencing
the test. Care is taken to ensure that heat radiation does not influence the specimen during
this period. The glow-wire tip temperature is measured by means of a sheathed fine-wire
thermocouple constructed and calibrated as described in IEC 60695-2-10.

– 20 – 62560  IEC:2011
– Any flame or glowing of the specimen shall extinguish within 30 s of withdrawing the glow-
wire, and any flaming drop shall not ignite a piece of the tissue paper, spread out
horizontally 200 ± 5 mm below the specimen. The tissue paper is specified in 4.187 of
ISO 4046-4.
The test is not made on parts of ceramic material.
13 Fault conditions
13.1 General
Lamps shall not impair safety when operated under fault conditions which may occur during
the intended use. Each of the following fault conditions is applied in turn, as well as any other
associated fault condition that may arise from them as logical consequence.
13.2 Extreme electrical conditions (dimmable lamps)
If lamps are marked with a voltage range, rated voltage is taken as the maximum of the
voltage range marked unless the manufacturer declares another voltage as the most critical
one. The lamp is switched on at ambient temperature (definition as in IEC/TS 62504 and
conditions as in Clause H.1 of IEC 61347-1) and adjusted to the most critical electrical
conditions as indicated by the manufacturer or the power is increased until 150 % of the rated
power is reached. The test is continued until the lamp is thermally stabilised. A stable
condition is reached, if the lamp cap temperature does not change by more than 1 K in 1 h
(test as described in IEC 60360). The lamp shall withstand the extreme electrical conditions
for at least 15 min, after stabilization is reached.
A lamp which fails safe and has withstood the extreme electrical conditions for 15 min, has
passed the test, provided the compliance (see 4.1 and 13.6) is fulfilled.
If the lamp contains an automatic protective device or circuit which limits the power, it is
subjected to a 15 min operation at this limit. If the device or circuit effectively limits the power
over this period, the lamp has passed the test, provided the compliance (see 4.1 and 13.6) is
fulfilled.
13.3 Extreme electrical conditions (non-dimmable lamps)
Lamps, which according to the marking, are not suitable for dimming, shall be tested as far as
possible according to Subclause 13.2 under the most adverse electrical conditions as
indicated by the manufacturer. If lamps are marked with a voltage range, rated voltage is
taken as the maximum of the voltage range marked unless the manufacturer declares another
voltage as the most critical one.

13.4 Short-circuit across capacitors
Only one component at a time is subjected to a fault condition.
13.5 Fault conditions across electronic components
Open or bridge points in the circuit where the diagram indicates that such a fault condition
may impair safety.
Only one component at a time is subjected to a fault condition.
13.6 Compliance
During the tests 13.2 to 13.5 the lamp shall not catch fire, or produce flammable gases or
smoke and live parts shall not become accessible.

62560  IEC:2011 – 21 –
To check if gases liberated from component parts are flammable or not, a test with a high-
frequency spark generator is made.
To check if accessible parts have become live, a test in accordance with Clause 7 is made.
After testing in 13.2 to 13.5, the lamp shall meet the insulation resistance requirements of 8.1
except the applied voltage shall be a DC voltage of approximately 1 000 V.
14 Creepage distances and clearances
The requirements of IEC 61347-1 apply except that for conductive accessible parts IEC
60598-1 is applicable.
