This International Standard is applicable to replaceable lamps (filament lamps and discharge
lamps) to be used in headlamps, fog-lamps and signalling lamps for road vehicles. It is
especially applicable to those lamps which are listed in IEC 60809. However, the standard
may also be used for other lamps falling under the scope of this standard, as well as for future
developments, e.g. such where the light is produced by light emitting diodes (LED).
It specifies requirements and test methods for the measurement of performance charac-
teristics such as lamp life, lumen 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 for the guidance of lighting and
electrical equipment design.
For some of the requirements given in this standard, 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.
NOTE In the various vocabularies and standards, different terms are used for "incandescent lamp"
(IEV 845-07-04) and "discharge lamp" (IEV 845-07-17). In this standard, "filament lamp" and "discharge lamp" are
used. However, where only "lamp" is written both types are meant, unless the context clearly shows that it applies
to one type only.
