1 Scope

The verification system table is suitable for testing the surface of the color measurement instruments. It sets the national standard for chroma units Purpose, a full set of basic measuring instruments included in the benchmark, basic metrology parameters of the benchmarks, with the aid of work benchmarks and subscripts Quasi-measuring instruments to the work of measuring instruments transfer colorimetric procedures, and pointed out that the uncertainty and basic verification methods Wait. Colorimetric measurement is divided into surface color measurement and light color measurement. The colorimetric measurement referred to in this verification system sheet refers to the surface Color measurement.

2 measurement reference equipment

2.1 Chroma National Benchmark 2.1.1 Chromaticity National benchmark for the recurrence of colorimetric units, through the chromaticity working reference board and a standard whiteboard, Secondary standard whiteboard and special standard reflector pass the value to the country to ensure the accuracy and unity of China's colorimetric values. Chromaticity The national benchmark consists of a baseline device and a reference whiteboard. 2.1.2 Chromaticity The national reference device enables absolute measurement of the spectral reflectance, the reference whiteboard is approximately perfect Reflector (perfectreflectingdiffuser). The magnitude of the chromaticity national baseline recurrence is the absolute spectral diffuse factor, determined by the International Commission on Illumination (CIE) The standard illuminant and the standard chromatic observer calculate the corresponding colorimetric values. Our country has established a national benchmark for colorimetric 0/d conditions. The 0/d condition refers to the lighting/viewing geometry, ie light The source is entering the illumination sample and the reflected light is diffused by the integrating sphere and received by the detector. 2.1.3 Chromaticity National benchmark measurement range, uncertainty in Table 1. Table 1, the uncertainty of the national standard of chroma Base Name Measurement Range Uncertainty 0/d Condition Chroma National Benchmark Y≥90 0.2800≤x, y≤0.4500 U (Y) = 0.8 (k = 2) U (x), U (y) = 0.0022 (k = 2) 2.2 Chroma National Working Baseline 2.2.1 in the chromaticity benchmarking on the basis of reference to the value of the work pass. Chroma National Working Reference by the chromatic reference value of the transmission device to compare the measured. The method is. Reference plate spectral diffuse reflection factor in the corresponding wavelength range calibration chromaticity reference device, by comparison method Spectral diffuse reflection factor for the reference plate. Chrominance reference white board is barium sulfate sprayed plate, requiring a higher diffuse reflection factor, good diffusion properties, spectral selectivity Small, stimulus value Y and color coordinates in D65 illuminant, CIE 1964 standard chromaticity observer (ie. 10 ° field of view) The range of x, y. Y≥90, 0.2800≤x, y≤0.4500. Chromaticity working reference board made of PTFE, Sulfur Barium, ceramic, opal glass and other components, requiring its optical properties are stable, easy to clean or easy to copy, the surface is smooth, both Uniform, no marks or scratches.
