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 60432-3 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This second edition of IEC 60432-3 cancels and replaces the first edition published in 2002,
Amendment 1 (2005) and Amendment 2 (2008). The document 34A/1567/FDIS, circulated to
the National Committees as Amendment 3, led to the publication of this new edition.
The main changes with respect to the previous edition are as follows:
– adapting the cold fill pressure requirements and tests for self-shielded lamps to the state of
the technology,
– introduction of requirements to fully cover photobiological safety according to IEC 62471.

60432-3 © IEC:2012 – 5 –
The text of this standard is based on the first edition, its Amendments 1 and 2, and the
following documents:
FDIS Report on voting
34A/1567/FDIS 34A/1585/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 60432 series, published under the general title Incandescent
lamps – Safety specifications can be found on the IEC website.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date,
the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

information on how to address IR hazards properly.
Compliance is checked by visual inspection.
2.3 Caps or bases
2.3.1 General
Caps or bases originally developed for single-capped ELV lamps shall not be used for general
purpose tungsten halogen lamps with rated voltages higher than 50 V.
NOTE Examples of such ELV fits are: G4, GU4, GY4, GX5.3, GU5.3, G6.35, GY6.35, GU7 and G53.
The GU10 base shall be used for aluminised reflector lamps only. The G9, GU10 or GZ10 base
shall be used for self-shielded lamps only.
Compliance is checked by inspection.
2.3.2 Creepage distances
The minimum creepage distance between contacts or between contacts and the metal shell of
the cap, if any, shall be in accordance with the recommendations in IEC 60061-4.
Compliance is checked by measurement.
2.3.3 Dimensions
If tungsten halogen lamps use standardized caps/bases they shall be in accordance with the
requirements of IEC 60061-1.
Compliance is checked on finished lamps by using the gauges of IEC 60061-3.

– 12 – 60432-3 © IEC:2012
Non standardized caps/bases shall be in accordance with the manufacturer's specification.
Compliance is checked by inspection.
2.4 Photobiological safety
The specific effective radiant UV power of self-shielded tungsten halogen lamps shall not
exceed:
– 2 mW/klm or,
– for reflector lamps 2 mW/(m ·klx).
Compliance is checked by measurement of the spectral power distribution.
NOTE Blue light and infrared hazards are covered by marking requirements.
2.5 Gas pressure of low-pressure self-shielded extra low voltage lamps
During operation, the gas pressure of single-capped low-pressure self-shielded ELV tungsten
halogen lamps shall be limited. This shall be achieved by restricting:
a) the cold fill pressure to less than 1 × 10 Pa (1 bar) for rated wattages above 50 W and up
to 100 W, and
b) the cold fill pressure to less than 4 × 10 Pa (4 bar) for rated wattages up to 50 W, and
c) the lamp volume to 1 cm maximum.
Compliance is checked by inspection and by means of the test specified in Annex B.
2.6 Safety at end of life of self-shielded lamps with rated voltages from range B or C
When tested under the specified conditions, lamp failure shall not be accompanied by
breakage of the bulb nor its ejection from the cap.
For bayonet capped lamps, it is also required that there shall not be an internal short-circuit to
the cap shell after the test.
The test conditions are:
– an induced-failure test in accordance with Annex F, or
– an operation-to-failure test.
The operation-to-failure test shall be carried out under the conditions specified for the life test
procedure in Annex A of IEC 60357:2002. The test rack circuit characteristics shall be in line
with Table E.1 of IEC 60432-1:1999. The test is continued until end of life.
NOTE 1 In the event of dispute the reference test method is the induced failure test.
NOTE 2 Some lamp designs are not suitable for testing with the induced failure test because a breakdown cannot
reliably be achieved. Such lamps, provided they are of voltage range B or C, will be submitted to an operation-to-
failure test as described above.
2.7 Information for luminaire design
Refer to Annex C.

3 Assessment
3.1 General
This clause specifies the method a manufacturer should use to show that his product conforms
to this standard on the basis of whole production assessment, in association with his test
records on finished products. This method can also be applied for certification purposes.
Subclause 3.2 gives details of assessment by means of the manufacturer’s records.
Details of a batch test procedure which can be used to make limited assessment of batches
are given in 3.3. Requirements for batch testing are included in order to enable the assessment
of batches presumed to contain unsafe lamps. As some safety requirements cannot be
checked by batch testing, and as there may be no previous knowledge of the manufacturer’s
quality, batch testing cannot be used for certification purposes nor in any way for an approval
of the batch. Where a batch is found to be acceptable, a testing agency may only conclude that
there is no reason to reject the batch on safety grounds.
3.2 Whole production assessment by means of manufacturer’s records
The manufacturer shall show evidence that his products comply with the particular
requirements of 3.2.1. To this end, the manufacturer shall make available all the results of his
product testing pertinent to the requirements of this standard.
The test results may be drawn from working records and, as such, may not be immediately
available in collated form.
The assessment shall be based in general on individual factories, each meeting the
acceptance criteria of 3.2.1. However, a number of factories may be grouped together,
providing they are under the same quality management. For certification purposes, one
certificate may be issued to cover a nominated group of factories, but the certification authority
shall have the right to visit each plant to examine the local relevant records and quality control
procedures.
For certification purposes, the manufacturer shall declare a list of marks of origin and
corresponding lamp families, groups and/or types which are within the scope of this standard
and manufactured in a nominated group of factories. The certificate shall be taken to include
all lamps so listed made by the manufacturer. Notification of additions or deletions may be
made at any time.
In presenting the test results, the manufacturer may combine the results of different lamp
families, groups and/or types according to column 4 of Table 1.
The whole production assessment requires that the quality control procedures of a
manufacturer shall satisfy recognized quality system requirements for final inspection. Within
the framework of a quality assurance system based also on in-process inspection and testing,
the manufacturer may show compliance with some of the requirements of this standard by
means of in-process inspection instead of finished product testing.
The manufacturer shall provide sufficient test records with respect to each clause and
subclause as indicated in column 5 of Table 1.

The period of review for assessment purposes need not be limited to a predetermined year, but
may consist of 12 consecutive calendar months immediately preceding the date of review.
A manufacturer who has met, but no longer meets the specified criteria, shall not be
disqualified from claiming compliance with this standard providing he can show that:
a) action has been taken to remedy the situation as soon as the trend was reasonably
confirmed from his test records;
b) the specified acceptance level was re-established within a period of:
1) six months for Subclause 2.6;
2) one month for the other clauses and subclauses.
When compliance is assessed after corrective action has been taken in accordance with items
a) and b), the test records of these lamp families, groups and/or types which do not comply
shall be excluded from the 12-month summation for their period of non-compliance. The test
results relating to the period of corrective action shall be retained in the records.
A manufacturer who has failed to meet the requirements of a clause or subclause where
grouping of the test results is permitted shall not be disqualified for the whole of the lamp
families, groups and/or types so grouped if he can show by additional testing that the problem
is present only in certain families, groups and/or types so grouped. In this case, either these
families, groups and/or types are dealt with in accordance with a) and b) as above or they are
deleted from the list of families, groups and/or types which the manufacturer may claim are in
conformity with the standard.
In the case of a family, group and/or type which has been deleted from the list, it may be
reinstated if satisfactory results are obtained from tests on a number of lamps equivalent to the
minimum annual sample specified in Table 1, required by the clause or subclause where non-
compliance occurred. This sample may be collected over a short period of time.
In the case of new products, there may be features which are common to existing lamp
families, groups and/or types, and these can be taken as being in compliance if the new
product is taken into the sampling scheme as soon as manufacture is started. Any feature not
so covered shall be tested before production starts.
3.2.1 Assessment of manufacturer’s records for particular tests
Table 1 specifies the type of test and other information which applies to the method of
assessing compliance to the requirements of various clauses and subclauses.
A design test need be repeated only when a substantial change is made in the physical or
mechanical construction, materials, or manufacturing process used to manufacture the relevant
product. Tests are required for only those properties affected by the change.
3.2.2 Sampling procedures for the whole production testing
The conditions of Table 1 apply.
The whole production running tests shall be applied at least once per production day. They may
also be based on in-process inspection and testing.
The frequency of application of the various tests may be different, providing the conditions of
Table 1 are met.
Whole production tests shall be made on samples randomly selected at a rate not less than
that indicated in column 5 of Table 1. Lamps selected for one test need not be used for other
tests.
– 18 – 60432-3 © IEC:2012
In relation to the safety at end of life (see 2.6), the manufacturer shall have a sampling plan
which does not deliberately exclude any of the types in his nominated list.
3.3 Assessment of batches
3.3.1 Sampling for batch testing
The lamps for testing shall be selected in accordance with a mutually agreed method so as to
ensure proper representation. Selection shall be randomly made as nearly as possible from
one-third of the total number of containers in the batch, with a minimum of ten containers.
In order to cover the risk of accidental breakage, a certain number of lamps in addition to the
test quantity shall be selected. These lamps shall only be substituted for lamps of the test
quantities if necessary to make up the required quantities of lamps for the tests.
It is not necessary to replace an accidentally broken lamp if the results of the test are not
affected by its replacement, provided the required quantity of lamps for the following test is
available. If replaced, such a broken lamp shall be neglected in calculating results.
Lamps having broken bulbs when removed from the packaging after transit shall not be
included in the test.
3.3.2 Number of lamps in the batch sample
There shall be at least 500 lamps (see Table 5).
3.3.3 Sequence of the tests
The testing shall be carried out in the order of the subclause numbers listed in Table 5, up to
and including Subclause 2.4. Subsequent tests may involve damage to the lamp and each test
sample shall be taken separately from the original sample.
3.3.4 Rejection conditions of batches
Rejection is established if any rejection number in Table 5, with due regard to Annex D is
reached, irrespective of the quantity tested. A batch shall be rejected as soon as the rejection
number for a particular test is reached
