1 Scope
This International Standard is applicable to replaceable and standardised lamps (filament
lamps, discharge lamps and LED light sources) to be used in headlamps, fog-lamps and
signalling lamps for road vehicles. In some applications, these lamps may be installed
as non-replaceable.
This standard is especially applicable to those lamps which are the subject of legislation.
In particular, it includes the lamps contained in Regulations No. 37, No. 99, No.
128 and its series of amendments of the Geneva Agreement of 20 March 1958 of the United
Nations Economic Commission for Europe (UNECE). However, the standard may be used
for other lamps falling under the scope of this standard, as well as lamps which are
subject of legislation but not contained in Regulations No. 37, No. 99 and No. 128,
e.g. the non-replaceable (filament) lamps and LED modules.
For replaceable and standardised lamps, the standard specifies the technical requirements
with methods of tests and basic interchangeability (dimensional, electrical and luminous)
for lamps of normal production and for standard (étalon) lamps.
For most of the requirements given in this standard, reference is made to the “relevant
lamp data sheet”. For all lamps listed in Clause 8, data sheets are contained in this standard or included by reference. For other lamps,
the relevant data are supplied by the lamp manufacturer or responsible vendor. It
could be based on national legislation.
Other requirements to replaceable and standardised lamps such as lamp life, luminous
flux maintenance, torsion strength and resistance to vibration and shock are specified
in IEC 60810. Such requiremen...
