GB/T 22879-2008 《Paper and board - Determination of CIE whiteness, C/2°( indoor illumination conditions)》 Related products
The GB/T 22879-2008 standard specifies a method for the determination of the whiteness of paper and Cardboard at C/2 ° (Illumination conditions). It is suitable for white paper and Cardboard with or without fluorescent whitening agent, not for colored paper containing fluorescent dyestuff. Help confirm the Color and luminance of paper by measuring the reflected light of paper under indoor lighting conditions.
