Colorimetric measurement instrument calibration system
Total 2 blood No. 1 Reflection
This calibration system is applicable to the determination of colorimeter bases on the surface of objects, it stipulates the use of color units (measured in absolute light reflectance), the use of color references, the full range of instruments included in the reference, the basic parameters and the judgment of the reference, the working reference and the procedure for the transfer of color unit values ​​of the instrument, and specifies its insufficient determination and basic calibration methods, etc.,
A metrological reference instrument
1 National Standard||t Because the national colorimetric measurement unit is used by the national colorimetric station, the national colorimetric measurement unit is used, and ... The internal average paint (fine area, positive system, etc.) is reflected by the color sea reflection material (about 95). The internal area of ​​the paint is less than 0.2, the total reflectance ratio Y plus the national color point standard is not guaranteed to meet this 0.4, the color coordinates and accuracy 00004
2 Color reference
2.1 Brush reference white board, composed of optical components, flat and uniform surface, milky white, etc., the number of plates is not less than 3-7m, the total reflectance of the standard board is 2.2. The uncertainty is .5, the color coordinates of the color work adhesive
J221-89
31 work standard door, the north optical stove can be determined, the surface is flat and uniform, and the white technology composition is not less than 4 pieces. The length of the fold is 380～78m, the uncertainty of the total reflection ratio of the working reference core is 0 and the uncertainty of the chromaticity coordinates is 0.06
Secondary measurement standard
4First-level standard reflector can be calibrated with secondary standards or special standard reflectors, and the color measurement instrument is used.
5The wavelength range of the first-level standard reflector with perfect reflection ratio is 38～79. The allowable error of total reflection ratio is the allowable error of the product, 0.020
6 The secondary standard special standard reflector is used to calibrate various two-color colorimeter, including white board, color makeup, blood and various color companion quantities.
7 The secondary standard and special standard reflector have a usage range of 380~78m to 40070C, and the error of the new working time is
. The three working instruments
8 The source color colorimeter, colorimeter and self-heating meter are measured by scientific comparison method.
