4 Method summary

In D65 standard illuminant and a 10 ° field of view of the conditions, the measured spectral reflection factor of the sample, the sample obtained by the integral operation tristimulus values X, Y, Z, calculated according to the colorimetry sample color L, a, Chou .

5 Instruments

Color measurement instrument. the instrument lighting conditions of observation may be vertical diffusion irradiation probe (o/d) or diffuse irradiation Sounding (d/o).

6 Sample

Sample was pretreated in an oven at 105 ℃ ± 5 ℃ drying 2h, after removal placed in a desiccator, cooled to room temperature.

7 measuring step

7.1 preheating equipment. 7.2 Selected D65 standard illuminant and a 10 ° field of view measuring conditions, with standard board calibrate the instrument. 7.3 Preparation of the sample according to the measurement requirements (quartz cuvette or otherwise sample preparation), until the test specimen surface should be smooth and free of cracks, placed in color measurement Colorimetric values measured on a sample instrument.
