SAFETY SPECIFICATIONS
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.
International Standard IEC 62035 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 1999, AMD1:2003 and
AMD2:2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition. Photobiological safety requirements are taken care of on basis of the risk group
concept of IEC 62471 and the technical report IEC TR 62778 on blue light hazard. This has
consequences for terms, marking, structure of 4.6, and introduction of a new symbol “Caution,
do not stare at light source”. Special attention is given to blue light hazard.

DISCHARGE LAMPS
(EXCLUDING FLUORESCENT LAMPS) –
SAFETY SPECIFICATIONS
1 Scope
This International Standard specifies the safety requirements for discharge lamps (excluding
fluorescent lamps) for general lighting purposes.
This International Standard is applicable to low-pressure sodium vapour lamps and to high-
intensity discharge (HID) lamps, i.e. high-pressure mercury vapour lamps (including blended
lamps), high-pressure sodium vapour lamps and metal halide lamps. It applies to single- and
double-capped lamps, having caps as listed in Annex A.
This standard only concerns safety criteria and does not take into account performance. The
performance standards IEC 60188, IEC 60192, IEC 60662, IEC 61167 and IEC 61549 should
be referred to for such characteristics.
It may be expected that lamps which comply with this standard will operate safely at supply
voltages between 90 % and 110 % of rated supply voltage and when operated with a ballast
complying with IEC 61347-2-9 and IEC 60923, with a starting device complying with
IEC 61347-2-1 and IEC 60927, and in a luminaire complying with IEC 60598-1.

Compliance is checked on unused lamps as follows:
a) presence and legibility by visual inspection;
b) durability by rubbing the area of the marking by hand for a period of 15 s, with a smooth
cloth dampened with water. After this test the marking shall still be legible.
4.2.2 Additional information to be provided
In addition to the above lamp marking, all details and provisions which are necessary to
ensure safe installation and use shall be given in the lamp manufacturer’s instructions.
Alternatively, the immediate lamp wrapping or container may be marked with the
corresponding symbol as shown in Annex H.
NOTE In North America, a suitable cautionary notice is required. Additional use of symbols is optional.
If applicable, information shall be given about:
a) the provision that the lamp shall be operated in an enclosed luminaire only (for symbol,
see Clause H.2);
b) the hazard associated with a high level of UV radiation emitted by the lamp (for symbol,
see Clause H.3). The value of the specified ultraviolet hazard efficacy of luminous
radiation shall be made available for proper luminaire design (see Clause F.5) if it
exceeds 6 mW/klm for non-reflector lamps or 6 mW/(m ·klx) for a reflector lamp;
c) the hazard associated with a high blue light radiance (for symbol see Clause H.6). The
threshold illuminance below which the luminaire cannot exceed risk group 1 for blue light
shall be made available for luminaire design if the lamp is in risk group 2 (see
Clause F.5);
d) the risk of the occurrence of a rectifying effect at the end of lamp life;
e) the hazard(s) that exist(s) when the outer envelope is broken (for symbol, see
Clause H.4).
4.3 Mechanical requirements
4.3.1 Requirements for caps
4.3.1.1 Dimensions
If lamps use standardized caps, they shall be in accordance with the requirements on the cap
data sheets of IEC 60061-1, listed in Table A.1 of this standard. Non-standardized caps shall
be in line with the lamp manufacturer’s documentation.
Compliance is checked on finished lamps by gauging and/or measurement. For standardized
caps, the gauges of IEC 60061-3, listed in Table A.1 of this standard shall be used.
4.3.1.2 Creepage distance
The minimum creepage distance between contact pin(s) or contacts and a touchable metal
shell of the cap shall be in accordance with the requirements of IEC 60061-4.
Compliance is checked by measurement.
4.3.1.3 Caps provided with keys
For lamps using cap types incorporating keys which ensure non-interchangeability with similar
lamp types, the correct cap/key version shall be used.

– 12 – IEC 62035:2014  IEC:2014
Compliance is checked by visual inspection.
4.3.2 Construction and assembly
4.3.2.1 General
Caps shall be so constructed and assembled to the bulbs that the whole assembly remains
intact and attached during and after normal operation.
Compliance is checked by carrying out the following tests.
4.3.2.2 Resistance to pull
Where lamps are so constructed that when being withdrawn from the lampholder a pull is
exerted and withstood without the cap or any part of the cap or bulb being loosened or pulled
apart.
Compliance is checked by the following pull test.
A pull in the direction of the lamp axis shall be applied for 1 min to:
a) unused lamps,
b) lamps after storage in a heating cabinet for a period of 2 000 h ± 50 h.
The pull values and heating cabinet temperatures are given in Table B.1.
Care shall be taken that the means (clamp, etc.) of applying the pull to the lamp does not
weaken the structure.
The pull shall be increased progressively from zero to the value given in Table B.1. The pull
shall not be applied with a jerk.
4.3.2.3 Resistance to torque
Where lamps are so constructed that, during insertion into or withdrawal from, the lampholder,
a torque is applied to the cap or parts of the cap or to the cap/bulb connection, the torque
shall be withstood without any loosening of the connections. For mechanically fixed screw
caps, an angular displacement between cap and bulb of not more than 10° is allowed.
Compliance is checked by the following torsion test.
A torque shall be applied to:
a) unused lamps,
b) lamps after storage in a heating cabinet for a period of 2 000 h ± 50 h.
The torque values and the heating cabinet temperatures are given in Table B.2. The torsion
test holders are specified in Figures C.1 and C.2.
Before each use, the test holder for screw caps shall be checked to ensure that it is clean and
completely free of lubricants and grease. The cap of the test lamp shall be placed in the
appropriate holder. Either the cap or the bulb may be mechanically clamped.
For some mechanically fixed screw caps, for example those positioned on a screw thread
shaped sealing area, it is necessary to clamp the shell and to apply the torque in both
directions.
IEC 62035:2014  IEC:2014 – 13 –
The torque shall be increased progressively from zero to the value given in Table B.2. The
torque shall not be applied with a jerk.
4.4 Electrical requirements
4.4.1 Parts which can become accidentally live
Metal parts intended to be insulated from live parts shall not be or become live. Any movable
conductive material shall be placed, without the use of a tool, in the most onerous position
before inspection.
On bayonet caps, any projection from the contact plate shall not come within 1 mm of metal
parts intended to be insulated.
R = 3 mm
IEC  1129/14
Figure 1 – Edison screw-capped lamp
On Edison screw caps any projection from the cap shell shall not project more than 3 mm
from the surface of the cap (see Figure 1).
Compliance is checked by either an appropriate automatic system or by visual inspection. In
addition, there shall be regular daily checks of the equipment or a verification of the
effectiveness of the inspection.
