Common use of Colorimetric test Clause in Contracts

Colorimetric test. Each of the retroreflective areas shall emit white light when it is illuminated with a standard illuminant A, with an observation angle of 1/3E and an illumination angle β1 = β2 = 0X (xx x0 = " 0X, x0 = 0E); in other words: the trichromatic coordinates "x" and "y" of the reflected light shall lie within the zone specified below: White: limit towards blue x $ 0.310 limit towards yellow x # 0.500 limit towards green y # 0.150 + 0.640x limit towards green y # 0.440 limit towards purple y $ 0.050 + 0.750x limit towards red y $ 0.382

Colorimetric test. Each of the retroreflective areas shall emit white light when it is illuminated with a standard illuminant A, with an observation angle of 1/3E and an illumination angle β1 = β2 = 0X 0E (xx x0 or β1 = " 0X5E, x0 β2 = 0E); in other words: the trichromatic coordinates "x" and "y" of the reflected light shall lie within the zone specified below: White: limit towards blue x $ 0.310 limit towards yellow x # 0.500 limit towards green y # 0.150 + 0.640x limit towards green y # 0.440 limit towards purple y $ 0.050 + 0.750x limit towards red y $ 0.382
