uporabljajo za enak namen kot sijalke prej navedenih oblik;
– bučke z vsemi vrstami zaključkov;
– vznožke B15d, B22d, E12, E14, E17, E26**, E26d, E26/5039, E27 ali E27/5139.
Kadar je to smiselno uporabno, se ta standard uporablja tudi za sijalke z bučkami in vznožki, ki niso navedeni zgoraj, vendar se uporabljajo za enake namene. Ta standard določa metodo, ki naj bi jo proizvajalec uporabil za dokazovanje, da je njegov izdelek v skladu s tem standardom na podlagi ocene celotne proizvodnje, in sicer v zvezi z njegovimi evidencami o preskusih končnih izdelkov. To metodo je mogoče uporabiti tudi za certificiranje. Navedene so tudi podrobnosti serijskega preskusnega postopka, ki ga je mogoče uporabiti za omejeno oceno serij. Ta standard obravnava le varnostna merila in ne upošteva delovanja sijalk glede na značilnosti svetlobnega toka, življenjske dobe ali porabe energije. Bralci naj za značilnosti glede tipov, ki se običajno uporabljajo za splošno uporabo v razsvetljavi, gledajo standard IEC 60064.

Overview

EN 60432-1:2000 (equivalent to IEC 60432-1:1999) defines safety and interchangeability requirements for tungsten filament incandescent lamps intended for domestic and similar general lighting purposes. The standard covers lamps with rated wattage up to and including 200 W and rated voltages from 50 V to 250 V. It applies to common bulb shapes (A, B, C, G, M, P, PS, PAR, R) and a wide range of cap types (for example B15d, B22d, E12, E14, E17, E26, E27 and variants). EN 60432-1:2000 replaces the earlier EN 60432 (1984) and focuses on lamp safety - not on luminous performance or life characteristics.

Key Topics

The standard addresses practical, testable safety requirements and documentation practices. Major technical topics include:

• Scope and definitions for categories, classes, rated voltage/wattage and end-of-life.
• Marking requirements: mandatory legible markings (manufacturer, rated voltage or voltage range, rated wattage) and special symbols for reflector/bowl-mirror lamps or restricted operating positions.
• Protection against accidental contact for screw lampholders - compliance with gauge checks referenced in IEC 60061.
• Lamp cap temperature rise (Δts) measured per IEC 60360.
• Mechanical requirements: resistance to torque and other cap/neck mechanical tests.
• Electrical safety: insulation resistance for insulated skirts, protection of accidentally live parts, and creepage distances for certain caps.
• Safety at end of life and requirements to limit hazards during lamp failure.
• Interchangeability and information useful for luminaire design.
• Assessment and quality control: whole-production appraisal, batch testing, sampling procedures and acceptance criteria (ref. IEC 60410, ISO 3951).
• Normative annexes with test procedures (torque, induced-failure, operation-to-failure), packaging symbols and sampling tables.

Applications and Who Uses It

EN 60432-1:2000 is essential for:

• Lamp manufacturers to design, test and declare safety compliance.
• Test laboratories and certification bodies performing type and batch testing or whole-production assessment.
• Luminaire designers and OEMs who need cap temperature and interchangeability information for safe lamp–fitting integration.
• Regulatory authorities and procurement teams specifying safe domestic lighting products.
• Technical writers and standards specialists preparing declarations of conformity and product labelling.

Practical benefits include improved user safety, consistent interchangeability across markets, and clear test methods for cap temperature, mechanical integrity and end-of-life safety.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60432-1 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
34A/873/FDIS 34A/887/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 3.

SAFETY SPECIFICATIONS –
Part 1: Tungsten filament lamps for domestic and
similar general lighting purposes
1 General
1.1 Scope
International Standard IEC 60432-1 specifies the safety and interchangeability requirements of
tungsten filament incandescent lamps for general lighting service having:
– rated wattage up to and including 200 W;
– rated voltage of 50 V to 250 V inclusive;
*
– bulbs of the A, B, C, G, M, P, PS, PAR or R shapes , or other bulb shapes where the lamps
are intended to serve the same purpose as lamps with the foregoing bulb shapes;
– bulbs with all kinds of finishes;
**
– caps B15d, B22d, E12, E14, E17, E26 , E26d, E26/50×39, E27 or E27/51×39.
As far as is reasonably practicable, this standard is also applicable to lamps with bulbs and
caps other than those mentioned above, but which serve the same purpose.
This standard specifies the method a manufacturer should use to show that his product
conforms to this standard on the basis of whole production appraisal in association with his test
records on finished products. This method can also be applied for certification purposes.
Details of a batch test procedure which can be used to make limited assessment of batches
are also given.
This standard is concerned with safety criteria only and does not take into account the
performance of tungsten filament lamps with respect to luminous flux, life or power
consumption characteristics. Readers should refer to IEC 60064 for such characteristics with
respect to types normally used for general lighting service.

remain at 240 V.
60432-1 © IEC:1999 – 15 –
2.2.2 Dichroic reflectorized (cool beam) lamps and bowl mirror lamps
The immediate lamp wrapping or container shall be marked with the relevant symbol as shown
in annex B.
2.2.3 Lamps with operating position limitations
For lamps requiring operating position limitations, such as some 60 W candle and round bulb
lamps capped with B22d or E27 caps which can comply with the requirement of the lamp cap
temperature rise only by excluding the cap-up position, the immediate lamp wrapping or
container shall be marked with the appropriate symbol. An example is shown in annex B.
NOTE – The requirements in 2.2.2 and 2.2.3 are intended as information for the end-user of the lamp.
2.3 Protection against accidental contact in screw lampholders
Dimensions of screw capped lamps shall be such that safety against accidental contact is
ensured according to IEC 60061.
The lamps shall satisfy the gauges, defined in IEC 60061-3 in accordance with table 1.

NOTE – The dash marking in the Gauge sheet No. column means that at the moment no such test system has been developed.
2.3.1 E14 capped lamps
E14 capped lamps shall satisfy the following requirements:
a) candle lamps shall be fitted with caps E14/25×17 and tested with gauge 7006-55;
b) round bulb, pigmy, tubular and reflector lamps having lamp neck reference diameters of
21 mm and greater shall be fitted with caps E14/25×17 and tested with gauge 7006-55;
c) round bulb, pigmy, tubular and reflector lamps having lamp neck reference diameters
between 16 mm and 21 mm shall be fitted with caps E14/23×15 or E14/20;
d) round bulb, pigmy, tubular and reflector lamps having lamp neck reference diameters
between 14 mm and 16 mm shall be fitted with caps E14/20.
In cases c) and d) a gauge is not required, because the choice of caps guarantees the same
degree of safety as in cases a) and b).

60432-1 © IEC:1999 – 17 –
2.4 Lamp cap temperature rise (Δt )
s
2.4.1 Average cap temperature rise
The average cap temperature rise per class of lamp manufactured in a period of 12 months
shall not exceed the following:
a) the appropriate value as specified in table 2; or
b) 45 K lower than the relevant values in table 2 where advantage is taken of the lower
maximum cap temperature of 2.5.4 b).
However, lamps fitted with E12, E17 and E26 caps with higher Δt values intended for special
s
applications are permitted, provided suitable cautionary notices accompany each lamp.
NOTE – In North America, lampholder and luminaire designs may be primarily aligned with the cap temperature rise
characteristics of common frosted, clear and white lamps. Therefore, lamps with other bulb finishes or other
characteristics yielding a higher cap temperature rise may require special cautionary notices.
2.4.2 Compliance
Compliance shall be checked by measurements of lamp cap temperature rise on lamps in the
same class in accordance with the test procedure specified in IEC 60360.
If the lamp is marked with a voltage range, the cap temperature rise shall be measured at the
mean voltage provided the limits of the voltage range do not differ by more than 2,5 % from the
mean voltage. For lamps with a wider voltage range, the measurement shall be at the highest
marked voltage.
NOTE – Table 2 shows upper limits for average cap temperature rise which apply to all lamps listed by wattage,
bulb and cap. In practice, several design features such as light centre length, mount shape and bulb finish affect
cap temperature rise, but such factors are encompassed in each limit.
2.4.3 Batch testing
For the testing of batches when the 20 lamp sample size is needed, the average shall not
exceed the appropriate value in accordance with 2.4.1, with an allowance of +9 K.
2.5 Resistance to torque
2.5.1 Caps
Caps shall be so constructed and assembled to the bulbs that they remain attached during
normal operation.
2.5.2 Unused lamps
For unused lamps, the lamp cap shall not move relative to the bulb when subjected to the
relevant torque value from table 3 as tested in accordance with C.1. Where the means of
attachment is other than by capping cement or adhesive, relative movement between bulb and
cap is permitted, provided it does not exceed 10°.
2.5.3 Resistance to heat
The lamp cap and capping cement or other means of attachment shall endure exposure to heat
at a level equal to the maximum cap temperature for which that class of lamp is designed.
The lamp cap shall not move relative to the bulb when subjected to the relevant torque values
of table 4 after the heating test specified in C.2 at the appropriate temperature of 2.5.4. In the
case where the means of attachment is other than by capping cement or adhesive, relative
movement between bulb and cap is permitted, provided it does not exceed 10°.

The heating treatment shall be conducted at one of the following levels:
a) the maximum cap temperature, in relation to cap type as specified in table K.1; or
b) for certain classes of lamps where 210 °C is specified in table K.1, the manufacturer may
elect to design lamps that can withstand a maximum cap temperature of 165 °C, in which
case the heating test is carried out at 165 °C, provided their rated wattage is 15 W or lower,
and the lamp is not a reflector or bowl mirror type.
NOTE – For special applications in North America, maximum cap temperatures lower than those shown in table K.1
may be assigned by the lamp manufacturer. When such a lower temperature lamp class is established, the
manufacturer is encouraged to:
– propose special limits for this standard;
– alert luminaire manufacturers.

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.
Clauses 3.2, 3.3 and 3.5 give 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 3.4 and 3.6. 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 the manufacturer’s records
3.2.1 The manufacturer shall show evidence that his products comply with the particular
requirements of 3.3. To this end, the manufacturer shall make available all the results of his
product testing pertinent to the requirements of this standard.
3.2.2 The test results may be drawn from working records and as such may not be
immediately available in collated form.
3.2.3 The assessment shall be based in general on individual factories each meeting the
acceptance criteria of 3.3. 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 relevant local records and quality control procedures.
3.2.4 For certification purposes, the manufacturer shall declare a list of marks of origin and
corresponding lamp categories or classes 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.
3.2.5 In presenting the test results, the manufacturer may combine results of different lamp
classes according to column 4 of table 6.
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.
3.2.6 The manufacturer shall provide sufficient test records with respect to each clause as
indicated in column 5 of table 6.
3.2.7 The number of non-conformities in the manufacturer’s records shall not exceed the limits
shown in annex F relevant to the Acceptable Quality Level (AQL) values shown in column 6 of
table 6.
60432-1 © IEC:1999 – 29 –
3.2.8 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.
3.2.9 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:
– six months for 2.4.1, 2.5.3 and 2.9;
– one month for other clauses.
When compliance is assessed after corrective action has been taken in accordance with items a)
and b), the test records of these lamp categories 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.
3.2.10 A manufacturer who has failed to meet the requirements of a clause where grouping of
the test results is permitted under 3.2.5 shall not be disqualified for the whole of the lamp
classes so grouped if he can show by additional testing that the problem is present only in
certain classes so grouped. In this case, either these classes are dealt with in accordance with
3.2.9 or they are deleted from the list of classes which the manufacturer may claim are in
conformity with the standard.
3.2.11 In the case of a category or class which has been deleted under 3.2.10 from the list
(see 3.2.4), 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 6, required by the clause
where non-compliance occurred. This sample may be collected over a short period of time.
3.2.12 In the case of new products, there may be features which are common to existing lamp
classes, 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.
3.3 Assessment of the manufacturer’s records of particular tests
3.3.1 Table 6 specifies the type of test and other information which applies to the method of
assessing compliance to the requirements of various clauses. For some particular tests, more
detailed information is given below.
A design test need only be repeated 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.
3.3.2 With regard to the resistance to torque after the heating requirements of 2.5.3, the
manufacturer has the option of two test procedures, as set out in annex C.
NOTE – Provided that the data from the variables method C.1.4 b), form a near Gaussian distribution, normal
statistical techniques may be used to assess compliance, and an equivalent degree of confidence to that obtained
using method C.1.4 a) may be achieved with the smaller samples. In this case the assessment shall apply the rules
set out in annex G.
60432-1 © IEC:1999 – 31 –
3.3.3 With regard to the cap temperature rise requirements of 2.4, the manufacturer’s records
shall show either:
– a design test, if the cap temperature rise of each lamp in the samples of five is at least 5 K
below the value of table 2; or
– the results of periodic testing, where the average shall not exceed the value of table 2.
Where assessment is made for a lesser period than the full 12 months, a coefficient of
variation of 5 % shall be assumed in making the assessment.
3.3.4 Creepage distance is assessed as a design test. If all five lamps of the sample meet the
requirements of 2.8, the test is passed. A non-conformity is recorded if two or more lamps fail.
If one lamp fails, a further sample of five is to be taken and if no further lamps fail, the test is
passed.
3.4 Rejection conditions of batches
3.4.1 With the exception of the cap temperature rise test, which is covered by 3.4.2, rejection
is established if any rejection number in table 7 is reached. Irrespective of the quantity tested,
a batch shall be rejected as soon as the rejection number for a particular test is reached.
3.4.2 For the batch test of lamp cap temperature rise, five lamps shall be first tested.
Provided that all the lamps have a cap temperature rise at least 5 K lower than the appropriate
values shown in table 2, then no further testing for cap temperature rise is necessary. If at
least one of the five lamps in the test has a cap temperature rise within 5 K of the appropriate
value in table 2, then a total of 20 lamps shall be tested and the average temperature shall not
exceed the requirements of 2.4.2.
3.5 Sampling procedures for whole production testing
3.5.1 The conditions of table 6 apply.
3.5.2 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 6 are met.
3.5.3 Whole production tests shall be made on samples randomly selected at a rate not less
than that indicated in column 5 of table 6. Lamps selected for one test need not be used for
other tests.
3.5.4 For whole production testing of the requirements for accidentally live parts, (see 2.7),
the manufacturer shall demonstrate that there is a continuous 100 % inspection.
3.5.5 In relation to the safety at end of life (see 2.9), the manufacturer shall have a sampling
plan which does not deliberately exclude any of the classes in his nominated list.
