Interinstrumental agreement between spectrocolorimeters

The aim of this work is to generate a scheme for the intercomparation of spectrocolorimeters which have the same optic configuration of illumination/viewing, in chromatics coordinates L α b in base to the ASTM recommendation E1164-02. In order to quantify the agreement interinstrumental of these equipments, we were utilized five Materials Reference Standard (MRC), in five points of the CIEL α b color space. The scheme proposed in this work can be applied in colorimetry to discriminate the existent of variations in chromatics coordinates CIEL α b generated for samples that can not taken as standards.
