Colorimetric colorimeter verification procedure
1 Scope
This procedure is applicable to the first verification, subsequent verification and in-use inspection of the photoelectric integral colorimetric color difference meter. Photoelectric product
The specification and identification of the fractional colorimeter and the measurement performance requirements in the prototype test can be carried out with reference to this regulation.

3 Overview
3.1 Principle
The colorimeter is used to measure the surface color and chromatic aberration of non-fluorescent objects. Colorimeter (including colorimeter, below)
The same is composed of three parts. the lighting system, the detection system and the data processing system, and the output result (or the necessary number)
Learning processing) is the tristimulus value X, Y, Z (or X10, Y10, Z10), calculated chromatic coordinates x, y or color
difference.
The total spectral sensitivity of the instrument (light source, optics) according to the color measurement principle recommended by the International Commission on Illumination (CIE)
The comprehensive response of the system and the detector should be in accordance with the relationship of formula (1) or formula (2).

cloth;
K1, K2, K3---wavelength-independent constants;
Τx(λ), τy(λ), τz(λ)---relative spectral transmission of a modified filter that fits the color vision characteristics of the human eye in the instrument
ratio;
