GB/T 22880-2008 《Paper and board - Determination of CIE whiteness, D65/10°(outdoor daylight)》 Related products
The GB/T 22880-2008 standard specifies a method for measuring the whiteness of paper and Cardboard under D65/10 ° (outdoor sunlight) conditions. It is suitable for white paper and Cardboard with or without fluorescent whitening agent, but not for colored paper containing fluorescent dyestuff. This method helps to judge the visual whiteness effect of paper by measuring the reflected light of paper.
