The standard "JJG 2028-2021 Diffuse Transmission Visual Density (Black and White Density) Measurement Instrument Verification System Table" specifies the calibration method and verification requirements for measurement instruments used for verification of Diffuse Transmission Visual Density Meters (also known as Black and white densitometer). The standard ensures the accuracy and reliability of Density Meters by establishing a verification system table. It is mainly applicable to the measurement of Black and White Density in printing, photography and Miscellaneous related industries. The standard details the verification equipment, operation steps, verification items and calibrated standards to ensure that the instrument can provide accurate test results under different working conditions. In addition, the standard also covers the relevant content of equipment maintenance and performance verification, which helps to improve the service life of equipment and measurement accuracy.
