Photometries
Daytime Color (X,Y)
The chromaticity coordinates and total luminance factor of the retroreflective sheeting conform to Table A Daytime Color Specifications Limit (see Note 1).
Color Test – Ordinary Colored Sheeting Conformance to standard chromaticity (x, y) and luminance factor (Y %) requirements shall be determined by instrumental method in accordance with ASTM E 1164 on sheeting applied to smooth aluminum test panels.
The values shall be determined on a spectrophotometer.
Computations shall be done for CIE Illuminant D65 and the 2° standard observer (see Note 2)
