This document is applicable to electric light sources (see Note 1) for use in automotive
applications, for example in road illumination devices and/or light signalling devices for road
vehicles.
It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject
to other legislations.
This document specifies the technical requirements for interchangeability for example
dimensional, electrical and photometrical characteristics, and includes test methods.
For the light sources listed in this document, the data sheets are contained either in this
document or are included by reference to UN Resolution R.E.5.
Performance requirements are specified in IEC 60810, for example life, torsion strength,
resistance to vibration and shock.
The requirements for miniature light sources for supplementary purposes, not subject to
legislation, are specified in IEC 60983.
NOTE 1 The terms "lamp" and "light source" are both used in this document to mean the same product, so the two
terms are interchangeable throughout this document.
NOTE 2 In various vocabularies and standards, different terms are used for "incandescent lamp"
(IEC 60050845:
1987, 845-07-04), "discharge lamp" (IEC 60050-845:1987, 845-07-17) and "LED lamp". In this
document "filament lamp", "discharge lamp" and "LED light source" are used, however, where only "lamp" or "light
source" is written, all light sources, independent of the technology used, are meant, unless the context clearly shows
that it applies to one kind of technology only. In the UN Regulations, the word "light source" is used for the products
specified in this document.
NOTE 3 Wherever the term "device" is used, it is meant to designate equipment which is used as a luminaire. It
can for instance take the form and purpose of a headlight or signal light.

IEC TR 61547-1:2020 is available as IEC TR 61547-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TR 61547-1:2020 describes an objective light flickermeter, which can be applied for the following purposes:
- measuring the intrinsic performance of all lighting equipment without the application of voltage fluctuations in terms of illuminance flicker; during this measurement, the lighting equipment is supplied with a stable mains;
- testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation disturbance on the AC mains in terms of illuminance flicker; during this test a set of defined voltage fluctuations are applied to the AC mains and the immunity of the lighting equipment to the disturbance is determined.
Apart from the above two purposes, the immunity performance of lighting equipment can also be tested against intentional voltage fluctuation on the AC mains arising for example from mains signalling. This is however not described in further detail in this document. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the scope of this document has been clarified to make a distinction between flicker testing without voltage fluctuations to measure the intrinsic performance of lighting equipment and flicker testing in which a specific set of voltage fluctuations are applied in order to measure the immunity of the lighting equipment to voltage fluctuations present on the mains;
- the test procedure for flicker testing has been clarified.

This document is applicable to filament lamps, discharge lamps, LED light sources and LED
packages to be used in road vehicles, i.e. in headlamps, fog-lamps, signalling lamps and
interior lighting. It is especially applicable to those lamps and light sources which are listed in
IEC 60809.
It specifies requirements and test methods for the measurement of performance characteristics
such as lamp life, luminous flux maintenance, torsion strength, glass bulb strength
and resistance to vibration and shock. Moreover, information on temperature limits, maximum
lamp outlines and maximum tolerable voltage surges is given as guidance for lighting and
electrical equipment design.
For some of the requirements given in this document, reference is made to data given in
tables. For lamps not listed in such tables, the relevant data are supplied by the lamp
manufacturer or responsible vendor.
The performance requirements are additional to the basic requirements specified in
IEC 60809. They are, however, not intended to be used by authorities for legal type-approval
purposes.

IEC 61280-4-4:2017 provides uniform methods of measuring polarization mode dispersion (PMD) of single-mode installed links. An installed link is the optical path between transmitter and receiver, or a portion of that optical path. These measurements can be used to assess the suitability of a given link for high bit rate applications, or to provide insight on the relationships of various related transmission attributes. This document focuses on the measurement methods and requirements for measuring long lengths of installed cabling that can also include other optical elements, such as splices, connectors, amplifiers, chromatic dispersion compensating modules, dense wavelength division multiplexing or multiplexer (DWDM) components, multiplexers, wavelength selective switches, re-configurable optical add drop multiplexer (ROADMS). This document focuses on the apparatus, procedures, and calculations needed to complete measurements. IEC TR 61282-9 explains the theory behind the test methods.

IEC 62150-3:2015 It has been found that some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when side forces are applied to the mated cable-connector assembly, resulting in variations in the transmitted optical power. The purpose of this part of IEC 62150 is to define physical stress tests to ensure that such optical connections (cable and receptacle) can continue to function within specifications. This standard specifies the test requirements and procedures for qualifying optical devices for sensitivity to coupled power variations induced by mechanical disturbance at the optical ports of the device. This standard applies to active devices with optical receptacle interfaces. This standard describes the testing of transceivers for use with single-mode connectors having either 2,5 mm or 1,25 mm ferrules. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- extension of application field to SC connector interface transceivers in addition to LC connector interface transceivers specified in the first edition as both transceiver interfaces are very important in the industry;
- addition of a new Annex E dealing with load value difference for connector type in Method A.

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, E26/5039, E27 or E27/5139.
This standard also covers single-ended lamps, within the above ratings, which are not direct
replacements for conventional tungsten filament lamps, but serve the same purpose.
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 are used in North merica and E26/25 caps are used in Japan.

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.

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, E26/5039, E27 or E27/5139.
This standard also covers single-ended lamps, within the above ratings, which are not direct
replacements for conventional tungsten filament lamps, but serve the same purpose.
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 are used in North merica and E26/25 caps are used in Japan.

IEC/TR 61341:2010 describes the method of measuring and specifying the centre beam intensity and the associated beam angle(s) of reflector lamps. It applies to: - incandescent, - tungsten halogen, - gas-discharge and LED based reflector lamps for general lighting purposes. It does not apply to lamps for special purposes such as projection lamps. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. Due to the increasing use of reflector equipped LED lamps, the scope has been broadened and measurement conditions been included in order to take account of these lamps. Further, for easier understanding of the relation between the different axis and different intensities, two figures have been added. The luminous intensity distribution shall be reported instead of the centre beam intensity, if the latter is very low ("butterfly" distributions).
