JIS Z 8724:1997 English Edition

Methods of colour measurement - Light-source colour

Abstract

This Japanese Industrial Standard specifies the methods of measurement for general light source colour by the XYZ colorimetric system based on 2 degree field of view, and the X10Y10Z10 colorimetric system based on 10 degree field of view, and the methods of measurement for the relative spectral energy distribution of the illuminating light used in calculating the tristimulus values of object colours. This Standard applies to the case of measuring the emission colour of the light source other than general illumination (for example, emission display). Lighting methods of various kinds of light source used for measurement are specified in the Annex.
