Graphical illustration of the measuring principles 8.1 Night visibility R is the coefficient of retroreflected luminance (night visibility) of road markings. The observation angle of 2.29° corresponds to the viewing distance of a vehicle driver of 30 m under normal conditions. The illumination angle is 1.24°. The angle definitions above are valid for EN 1436.
Technical specification Observation distance: Equivalent to 30 m, according to CEN geometry Observation angle: EN 1436: 2,29° ASTM E1710: 1.05° Illumination angle: : EN 1436: 1,24° : ASTM E1710: 88,76° Test area (WxL): 50 mm x 160 mm (2” x 6.3”) Comparison standards: 50 mm x 150 mm (2”...
