Traffic control equipment - Signal heads
This document applies to signal heads with one or more signal lights of the colours red, yellow and/or green signal lights for road traffic with 200 mm and 300 mm roundels and to optical units to be integrated in signal heads to produce the individual signal lights. It defines the product characteristics for the visual, structural, environmental performances and testing of signal heads and optical units for pedestrian and road traffic use, and the rules for the evaluation of the conformity of these products.
This document can be partly or fully applied on a voluntary basis to other signal heads outside of the scope specified above like for instance white optical units or small signal heads with a diameter smaller than 200 mm.

Introduction
Signal heads are mainly used to transfer safety messages to the road user to achieve specific reactions. Signal
heads in road traffic transfer this information optically by signal lights which have a specific meaning and which
differ in their colour of light and in the design of their illuminating surface.
The visibility of a signal light depends on the colour, luminous intensity, luminous intensity distribution,
luminance and luminance uniformity, the surrounding luminance (background luminance), the size of the
illuminating area, the phantom light and the distance and angle between observer and signal head.
Four angular distributions of luminous intensities for signal lights are specified. The user can choose between an
extra wide, wide, medium and narrow beam signal to obtain a good recognition of the signal for short distances
in urban areas, for long distances in rural areas. To achieve a good performance the standard provides a number
of different performance levels and two different diameters for the optical units.
This document does not require limits for the recognition of red or green signals with reduced luminous
