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 60432-2 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This standard shall be used in conjunction with IEC 60432-1.
This consolidated version of IEC 60432-2 consists of the second edition (1999) [documents
34A/884/FDIS and 34A/898/RVD], its amendment 1 (2005) [documents 34A/1119/FDIS and
34A/1128/RVD] and its amendment 2 (2012) [documents 34A/1533/FDIS and 34A/1560/RVD].
The technical content is therefore identical to the base edition and its amendments and has
been prepared for user convenience.
It bears the edition number 2.2.

Part 2: Tungsten halogen lamps for domestic
and similar general lighting purposes



1 General
This standard shall be used in conjunction with IEC 60432-1.
1.1 Scope
This part of IEC 60432 specifies the safety and the related interchangeability requirements of
tungsten halogen lamps for general lighting service. It covers those tungsten halogen lamps
that are used as direct replacements for conventional tungsten filament lamps as well as new
tungsten halogen lamps which have no correspondence in IEC 60432-1, but for which the
safety and interchangeability requirements are treated by this standard in conjunction with IEC
60432-1. These tungsten halogen lamps have the following characteristics:
– rated wattage up to and including 250 W;
– rated voltage of 50 V to 250 V inclusive;
– caps B15d, B22d, E12, E14, E17, E26, E26d, E26/50x39, E27 or E27/51x39.
Lamps complying with this standard are self-shielded, but need not be marked with a special
symbol. As they are direct replacements for conventional tungsten filament lamps, there will
be no corresponding luminaire marking.
NOTE 1 There is no implication that a tungsten halogen lamp used as a substitute for an incandescent tungsten
filament lamp would use the same bulb shape as the original incandescent lamp.
NOTE 2 There are two variations of E26 caps which are not fully compatible: E26/24 caps used in North America
and E26/25 caps used in Japan.
NOTE 3 Self-shielded lamps are lamps for which the luminaire needs no protective shield.
This part of IEC 60432 covers photobiological safety according to IEC 62471 and
IEC/TR 62471-2. Lamps covered by this part of IEC 60432 do not reach risk levels that require
risk group marking.
1.2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.

Annex A
(normative)

Alternative induced failure test

A.1 Test circuit and equipment
The requirements of clauses D.1 and D.2 of IEC 60432-1 apply, except that instead of a pulse
generator a laser of adequate power shall be used to induce burn-out of the filament.
NOTE An example of a suitable laser is a neodymium-glass laser.
A.2 Test procedure
The lamp to be tested shall be inserted in the lampholder and the safety cover put in place.
Through a small hole in the cover, the laser beam shall be aligned and focused on the lamp
filament.
The lamp shall be switched on, applying rated voltage only. After complete warm-up of the
lamp, a laser pulse shall be applied.
If the lamp remains alight, the output power of the laser shall be increased and the laser pulse
shall be applied again. This procedure shall be repeated until burn-out of the filament is
achieved.
NOTE If the focusing of the laser beam is disturbed by the finish of the lamp or the structure of the outer
envelope, specially prepared samples should be used.
A.3 Inspection and assessment
After the test, each test lamp is examined. If:
a) the bulb is no longer intact;
b) or the bulb is detached from the cap;
c) or, for bayonet caps only, there is a short circuit between either contact and the shell,
then the lamp is deemed to have failed the test and is counted as a non-conformity.
