"SH/T 1833-2022 Determination of color difference of synthetic raw rubber color difference meter" stipulates the method of using color difference meter to measure the color difference of synthetic raw rubber. This standard applies to light-colored samples of bulk synthetic raw rubber such as butadiene rubber, styrene-butadiene rubber, nitrile rubber, ethylene propylene rubber, isoprene rubber and butyl rubber. By placing the sample on the color difference meter, the reflection signal to light is measured, and the color difference value is calculated using the CIE DE2000 formula. This standard emphasizes the use of fully automatic color difference meters that comply with the CIE1964 Supplementary Standard of the International Commission on Illumination, and ensure that software capable of calculating color differences is provided. Experimenters using this standard should have formal laboratory operation experience, and at the same time take appropriate safety and health measures, in accordance with the relevant requirements of national laws and regulations.
