Description

The differences between ITS-90 and IPTS-68 (International Practical Temperature Scale of 1968) above 1235 K are described. It is shown that none of the following CIE (Commission Internationale de l'Eclairage or International Commission on Illumination) definitions or recommendations require revision because of the introduction of the ITS-90: International Lighting Vocabulary definitions; CIE Standard Illuminants A, D(65), other illuminants; and sources for realizing CIE Illuminants. The effect of the ITS-90 on previously calibrated sources for realizing CIE illuminants is negligibly small
