Uncertainty evaluation of illuminant chromaticity for color luminance meterYU Pei-ying Shanghai Institute of Measurement and Testing Technology, Shanghai 201203, ChinaAbstract:National verification regulation for luminance meter, JJG 211-2005 was published and implemented. This regulation was used to verify either luminance meter or color one, and calibration of illuminant chromaticity was required. During color luminance meter calibrating, its standard reflection shade guide was the same as that for colorimeter calibration, and these standard values A/2,0/45 according to certificate of standard reflection shade guide were used. It is proved that method of this new verification regulation is correct, standard reflection shade guide for colorimeter calibration could be used in color luminance meter calibration, and its calibration results is very well according to experimental data of illuminant chromaticity parameters for color luminance meter and measurement uncertainty.[著者文摘]
