The NF T36 - 007-2-2011 standard defines CIE Standard light sources for use in Colorimetry, including CIE Standard light source A and D 65. CIE Standard light source A simulates tungsten filament lighting with a Color temperature of about 2856K; CIE Standard light source D65 represents average daylight with a Color temperature of about 6500K. The relative Light spectrum Power distribution of these Light sources covers the Wavelength range from 300nm to 830nm for Color measurement and evaluation, ensuring Color conformity and comparability under different lighting conditions.
