EN ISO CIE 11664-4 Colorimetry, Part 4: Standard Test for CIE Color Space

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO CIE 11664-4 testing. This standard specifies a method for calculating the coordinates of the CIE 1976 L*a*b* color space, including lightness, color, and hue relations.

EN ISO CIE 11664-4 Colorimetry, Part 4: Standard Test for CIE Color Space

It includes two methods for calculating Euclidean distances in this space to represent the perceived magnitude of color differences.

This standard applies to tristimulus values ​​calculated using the color matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This standard can be used to specify color stimuli perceived as belonging to a reflecting or transmitting object when three-dimensional space must be smoother than tristimulus space.

This standard does not apply to color stimuli that appear to emit light as a primary light source or are perceived as belonging to an area that appears to reflect such light reflectively.

This standard is applicable to self-luminous displays such as cathode ray tubes if used to simulate reflected or transmitting objects and the stimuli are properly normalized.
