materials are specially designed materials that cast back
a certain quantity of light from their surface, in accordance
with their design and technical specifications.
everyday life, the reflection of light enables us to "see"
the things around us.
traffic, particularly under the conditions of reduced visibility,
it is necessary to make the vehicles better visible, which
is achieved by the use of reflective materials.
signs in cities are made of material with the luminous intensity
of 70 candelas (Cd)*.
motorways and highways, traffic signs are made of material
whose luminous intensity is 250 - 600 Cd*.
to the Croatian norm of ECE R 70.01, the dimension plates
are made with the luminous intensity of 800 Cd*.
What is the candela (Cd)? · The candela is a
unit of luminous intensity, defined as the quantity of light
cast back from a certain surface.
signs in the city: luminous intensity 70 Cd
signs outside the city: luminous intensity 250 Cd
plate in accordance with the norm 70.00: luminous intensity
- The plate in accordance with the norm 70.01: luminous intensity 800 Cd
marker for contour marking; luminous intensity 550-800 Cd
marker for distinguishing marking; luminous intensity 150
- 450 Cd
