ISO 11664-1 Colorimetry - CIE Standard Colorimetric Observers

EUROLAB laboratory provides testing and compliance services within the scope of ISO 11664-1 standard. This standard specifies color matching functions for use in colorimetry. Two sets of color matching functions are specified.

ISO 11664-1 Colorimetry - CIE Standard Colorimetric Observers

The set of color matching functions, color matching functions for the CIE 1931 standard colorimetric observer represents the color matching properties of observers with normal color vision for visual field sizes of about 1° to about 4° angular subtense for vision at photopic adaptation levels.

The set of color matching functions, color matching functions for the CIE 1964 standard colorimetric observer, represents the color matching properties of observers with normal color vision for angular subtense visual field sizes greater than about 4° for vision at sufficiently high photopic levels and for spectral power distributions with no participation. Retinal rod receptors are expected to increase.
