ISO 23603:2005

Standard method of assessing the spectral quality of daylight simulators for visual appraisal and measurement of colour

ISO/CIE 23603:2005 specifies a method of assessing the spectral quality of the irradiance provided by a daylight simulator to be used for visual appraisal of colours or for colour measurements and a method of assigning a quality grade to the simulator. It specifies the maximum permissible deviation of the chromaticity of the simulator from the chromaticity of the CIE standard daylight illuminant or CIE daylight illuminant being simulated, for a simulator to be graded by this method.
