Safety requirements
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) 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.

INTRODUCTION
With IEC 62471 and IEC/TR 62471-2, there are horizontal requirements available that need to
be introduced into product standards, e.g. to IEC 60968. The horizontal requirement is
transformed into a requirement for self-ballasted lamps.
The lamps within the scope of this standard are general lighting service (GLS) lamps
according to the definition 3.11 in IEC 62471:2006. ".lamps intended for lighting spaces that
are typically occupied or viewed by people.".
According to Clause 6 of IEC 62471:2006, radiation of GLS lamps is measured at a distance
equivalent to 500 lx.
Measured at the 500 lx distance, GLS lamps will not exceed risk group 1 for blue light hazard
and risk group 0 for IR radiation. This combination of risk group and hazard does not require
marking (Table 1 of IEC/TR 62471-2:2009).
Hazards from UV radiation of GLS lamps will be covered by Clause 14 of IEC 60968.
Hence, IEC 62471 does not require any additional marking for GLS lamps.

other gas-discharge lamps with integrated means for controlling starting and stable operation
(self-ballasted lamps), intended for domestic and similar general lighting purposes, having:
– a rated wattage up to 60 W;
– a rated voltage of 100 V to 250 V;
– Edison screw or bayonet caps.
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are under consideration.
This part of the standard covers photobiological safety according to IEC 62471 and
IEC/TR 62471-2.
Blue light and infrared hazards are below the level which requires marking.

the lamp with the UV hazard function S (λ). Information about the relevant UV hazard function is given in
UV
IEC 62471. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the
possible influence of optical radiation on materials, like mechanical damage or discoloration.
4 General requirement and general test requirements
4.1 Self-ballasted 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 All measurements unless otherwise specified, are carried out at rated voltage and
frequency and in a draught-proof room at (25 ± 1) °C.
If lamps are marked with a voltage range, rated voltage is taken as the mean of the voltage
range marked.
4.3 Self-ballasted lamps are non-repairable, factory sealed units. They shall 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, lamps
specially prepared so that a fault condition can be simulated shall be submitted for testing
(see Clause 13).
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 trade mark, 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 either on
the lamp or packing or in the installation instructions:
a) lamp current;
b) burning position if restricted;
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;
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 symbol in
Figure 1 may be used:
60968 © IEC:2012 – 9 –

5.3 Compliance is checked by the following:
a) presence and legibility of the marking required in 5.1 – by visual inspection;
b) 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;
c) availability of information required in 5.2 – by visual inspection.
6 Interchangeability
6.1 Interchangeability shall be ensured by the use of caps in accordance with IEC 60061-1.
6.2 Compliance of the combination of cap and bulb is checked by the use of gauges for
checking the dimensions controlling interchangeability in accordance with Table 1.
The gauges are those shown in the standard sheet included in IEC 60061-3.

7 Protection against electric shock
Self-ballasted lamps shall be so constructed that, without any additional enclosure in the form
of a luminaire, no internal metal parts or live metal parts of the lamp cap are accessible when
the lamp is installed in a lampholder according to IEC 60238.
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 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.
NOTE Requirements for E26 caps are under consideration.
Lamps with B22 or B15 caps are subject to the same requirements as normal incandescent
lamps with this cap.
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 current-carrying metal
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 d.c. voltage of
approximately 500 V, 1 min after application of the voltage. The insulation resistance between
current-carrying metal 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.
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 a.c. voltage as follows:
– ES caps: between accessible parts and parts of screw caps (accessible parts of insulating
material are covered with metal foil):
• type HV (220 V to 250 V): 4 000 V r.m.s.

60968 © IEC:2012 – 11 –
• type BV (100 V to 120 V): 2U + 1 000 V
Value U = rated voltage.
During the test, the eyelet and the shell of the cap are short-circuited.
Initially, no more than half the prescribed voltage is applied. It is then gradually raised to
the full value.
No flash-over or breakdown shall occur during the test. Measurements shall be carried out
in the humidity cabinet.
NOTE The distance between the foil and the current-carrying parts is under consideration.
– Bayonet caps: between shell and contacts (under consideration).
9 Mechanical strength
Torsion resistance: 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 below.
B22d . 3 Nm
B15d . 1,15 Nm
E26 and E27 . 3 Nm
E14 . 1,15 Nm
The test is made 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 uncemented caps, relative movement between cap and bulb is permitted
provided it does not exceed 10°.
After the mechanical strength test, the sample shall comply with the requirements of
accessibility (see Clause 7).
10 Cap temperature rise
The cap temperature rise ∆t of the complete lamp during run-up, stabilization period and after
s
stabilization shall not exceed the values mentioned below when measured under the
conditions specified in IEC 60360:
B22d . 125 K
B15d . 120 K
E27 . 120 K
E14 . 120 K
E26 . under consideration
Measurement shall be carried out at rated voltage. If the lamp is marked with a voltage range,
it shall be measured at the mean voltage of that range, provided the limits of the voltage
range do not differ by more than 2,5 % from the mean voltage. For lamps with a wider range,
the measurement shall be made at the highest value of the range.

– 12 – 60968 © IEC:2012
11 Resistance to heat
Self-ballasted lamps 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.
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 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.
If the surface under test bends, the part where the ball presses is 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.
________
*
Under consideration.
60968 © IEC:2012 – 13 –
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.
– 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
± 5 mm below the specimen.
horizontally 200 mm
The test is not made on parts of ceramic material.
13 Fault conditions
The 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
conditions that may arise from it as logical consequences. Only one component at a time is
subjected to a fault condition.
a) In a switch-start circuit, the starter is short-circuited.
b) Short-circuit across capacitors.
c) The lamp does not start, because one of the cathodes is broken.
d) The lamp does not start, although the cathode circuits are intact (de-activated lamp).
e) The lamp operates, but one of the cathodes is de-activated or broken (rectifying effect).
f) Opening or bridging other points in the circuit where the diagram indicates that such a
fault condition may impair safety.
Examination of the lamp and its circuit diagram will generally show the fault conditions which
should be applied. These are applied in sequence in the order that is most convenient.
The manufacturer or responsible vendor shall submit a specially prepared lamp with the
relevant fault condition, where possible in such a way that by operating a switch outside the
lamp the fault condition is introduced.
Components or devices in which a short-circuit does not occur shall not be bridged. Similarly,
components or devices in which an open circuit cannot occur shall not be interrupted.
Manufacturers or responsible vendors shall produce evidence that the components behave in
a way that does not impair safety, for instance, by showing compliance with the relevant
specification.
In the case of fault conditions a), b) or f), compliance is checked by operating the sample free
burning at room temperature and at a voltage between 90 % and 110 % of the rated voltage
or, in case of a voltage range, at a voltage between 90 % and 110 % of the mean voltage of
that range until stable conditions have been reached, then introducing the fault condition.
In the case of fault conditions c), d) or e), the same operating conditions apply but the fault
condition is introduced at the start of the test.

– 14 – 60968 © IEC:2012
The sample is then tested a further 8 h. During this test it shall not catch fire, or produce
flammable gases and live parts shall not become accessible.
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.
The insulation resistance (see 8.2) is checked with a d.c. voltage of approximately 1 000 V.

Both joints of this finger may be bent through an angle of 90 , but in one and the same direction only.
Using the pin and groove solution is only one of the possible approaches in order to limit the bending angle to 90°.
For this reason dimensions and tolerances of these details are not given in the drawing. The actual design shall
ensure a 90° bending angle with a 0° to +10° tolerance.

14 UV radiation
The specific effective radiant UV power emitted by the lamp shall not exceed the value of
2 mW/klm. For reflector lamps, it shall not exceed the value of 2 mW/(m²⋅klx).
NOTE In IEC 62471, exposure limits are given as effective irradiance values (unit W/m²) and for risk group
classification the values for general lighting lamps are to be reported at an illuminance level of 500 lx. The
borderline for risk group exempt is 0,001 W/m² at an illuminance level of 500 lx. This means the specific value,
related to the illuminance, is 0,001 divided by 500 in W/(m²⋅lx), which is 2 mW/(m²⋅klx). Since lx = lm/m², this
equals 2 mW/klm specific UV power.
Compliance is checked by spectroradiometric measurement, under analogue conditions as for
the lamp’s electrical and photometric characteristics as given in IEC 60901.

Exigences de sécurité
AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de la CEI. La CEI n'est responsable d'aucun des services effectués par les organismes de
certification indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire
