LAMPS FOR ROAD VEHICLES –
DIMENSIONAL, ELECTRICAL AND LUMINOUS REQUIREMENTS
1 General
1.1 Scope
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 the subject of legislation. In particular, it
1)
includes the lamps contained in Regulations No.37and No.99 of the Geneva Agreement of
20 March 1958 of the United Nations Economic Commission for Europe (ECE). However, the
standard may be used for other lamps falling under the scope of this standard.
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 data
sheet". For all lamps listed in Clause 5 , data sheets are contained in this standard. For other
lamps the relevant data are supplied by the lamp manufacturer or responsible vendor. It
could be based on national legislation.
Other requirements such as lamp life, lumen maintenance, torsion strength and resistance to
vibration and shock are specified in IEC 60810. The latter standard also gives information for
guidance of lighting equipment design, such as temperature limits and maximum lamp
outlines.
Road vehicle lamps for supplementary purposes which are not the subject of legislation are
specified in IEC 60983.
In countries which legislate for approval, for example under the terms of the aforementioned
ECE Regulations, it is suggested that reference is made to this standard for assessment of
compliance. IEC 60810 and IEC 60983 are not intended for that purpose.
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.

relevant filament lamps with colourless bulb.
Compliance shall be checked by the tests specified in annex C.
2.8 Check on optical quality
This requirement applies only to double filament lamps with internal shield for headlamps
emitting an asymmetrical dipped beam when the relevant regulation requires such a test.
The check on optical quality shall be carried out at a voltage such that the test luminous flux
is obtained.

directive or standard.
2.8.2 6 V and 24 V lamps emitting white light
The sample which most nearly conforms to the rated dimension values shall be tested in an
appropriate standard headlamp and it shall be verified that the assembly comprising the
aforesaid headlamp and the filament lamp being tested meets the light-distribution
requirements laid down for the dipped beam in the relevant regulation, directive or standard.
Deviations not exceeding 10 % of the minimum values will be acceptable.
