GB/T 20147.3-2023 "Colorimetry—Part 3：CIE tristimulus values"

This standard specifies the method for calculating the tristimulus values of Color stimuli with known Light spectrum distributions. It is suitable for Color stimuli generated by self-luminous Light sources or reflection and transmission objects. The method includes the tabulation and calculation of the Color stimulus function in the Wavelength range, and the method used is determined according to the actual Wavelength range. It is suitable for chroma calculation, the design and manufacture of chroma measuring instruments and applications in related fields.
