适用范围:This European Standard specifies a method for the colorimetric characterization of optically clear, slightly tinted liquids (products) by broad-band measurement of pure transmittance with tristimulus value measuring filters as TX, TY and TZ. Since the tristimulus value measuring filters of simple tristimulus colorimeters meet the Luther condition to a limited extent only it is necessary to deliberately restrict the liquids (products) to slightly tinted ones in order to be able to measure them sufficiently exactly with a single calibration against uncoloured distilled water. If the colour of heavily coloured solutions is measured with simple tristimulus colorimeters, it is necessary to calibrate the instrument with a spectrometrically measured standard of very similar colour.
