4.4 The color of the same sample should be uniform and consistent, and there should be no obvious color difference when observed by naked eyes. 5 Measurement method
5.1 Basic method
5.1.1 Sample
Instrument measurement
Use a flat sample with a size of not less than 25 mm×20 mm and a surface roughness R of ≤0.08 um5.1.2 Instrument
5.1.2.1 Use an integrating sphere spectrophotometer that meets the requirements of 13.1 in GB 3979. 5.1.2.2 The standard light source is D65 light source, C light source or A light source specified in 4.3, 4.2 and 4.1 of GB 3978. 5.1.2.3 The lighting and observation conditions shall be the 0/t conditions specified in 5.3 of GB3978, that is, the measurement of the specular reflection component shall be carried out without using a gloss absorber and under the "vertical/diffuse" conditions. 5.1.3 Measurement process
5.1.3.1 According to 3.2 of GB3979, measure the spectral reflectance p(a) of the sample. 5.1.3.2 According to 3.2.4 of GB3979, the three stimulus values ​​X, Y, and Z shall be calculated using the equal wavelength interval method. See formula (1). X =Es()()p(A)A
Y Es(a)yta)p(a)aa

Tristimulus values ​​in the XYZ colorimetric system.
Lunar colorimetry
The standard color plate shall conform to the chromaticity coordinates and stimulus values ​​given in Table 1 as the reference color scale for daylight colorimetry, and its size shall not be less than 25 mm × 20 mm.
5.2.2 Observation conditions
The lighting observation conditions shall be the 45/0 or 0/45 conditions specified in 5.1 of GB3978, using Ds light source, C light source, A light source or natural light, with an illumination of 001x or more, and a background grayscale of N6. 5.2.3 Visual colorimetry
Place the sample and the standard color plate side by side, cover the surface with a tracing paper, and then press it with a white mask with a rectangular opening. Visually compare the color wavelength a of the sample and the standard color plate from the opening
