Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards
bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through
IS0 technical committees. Each member body interested in a subject for which a technical committee has
International organizations,
been established has the right to be represented on that committee.
governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The main task of IS0 technical committees is to prepare International Standards. In exceptional
circumstances a technical committee or subcommittee may propose the publication of a Technical Report of
one of the following types:
- type 1, when the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts;
- type 2, when the subject is still under technical development or where for any other reason there is the
future but not immediate possibility of an agreement on an International Standard;
- type 3, when a technical committee or subcommittee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example).
Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether
they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to
be reviewed until the data they provide are considered to be no longer valid.
ISO/TR 11842, which is a Technical Report of type 3, was prepared by lSO/TC 22, Road vehicles,
Subcommittee SC 8, Lighting and signaling.

Road vehicles - Comparison of statutory photometric
requirements in various countries for lighting devices
1 Scope
This Technical Report compiles photometric requirements for headlamps [main beam (upper beam) and
dipped beam (low beam)] and fog lamps from existing provisions for lighting devices, established by national
or international legislations in various countries.

The illumination produced on the screen by the driving beam shall meet
the following requirements:
The point of intersection HV of the lines hh and w shall be situated
within the isolux 90% of maximum illumination. This maximum value shall
not be less than "32 lux.
Starting from point W, horizontally to the right and left, illumiantion
shall be not less than 16 lux up to a distance of 1.125 m and not less
than 4 lux up to a distance of 2.25.m. (Where the flux of the standard
filament lamp used for measurements is other than 700 lumens, the measurements
as taken-must be corrected proportionally to the ratio of the fluxes.)
The screen illumination values mentioned under (c) and (d) shall
(4
be measured by means of a photo-electric cell, the useful area of which
shall be contained within a square of 65 mm side.
