Following statements take part in CIE 140 (page
5)
In the (cg) system of coordinates, luminous
intensities will be required at the angular
intervals stated below. For all luminaires the
angular intervals in elevation (g) should at most
be 2.5 from 0 to 90 plus the permissible
maximum field angle of elevation minus the
measurement angle of elevation, for the
luminaire. In azimuth the intervals can be varied
according to the symmetry of the light
distribution from the luminaires as follows -
Luminaires with no symmetry about c 0 180
plane the intervals should at most be 5,
starting at 0, when the luminaire is in its
measurement angle of elevation and ending at
355.

I-table of road lighting luminaire with no
symmetry light distribution should be given
according to those definitions.

According to CIE 140, the observers eye height
1.5 m above road level, is positioned
transversely a quarter of road width from the
carriageway edge, and longitudinally at a
distances in meters of 2.75 (mounting height
1.5) in front of the field of calculation. In
EN13201 Part 3, it is stated that the
observers eye, is positioned in the centre line
of each lane in turn by keeping all other parts
same.
