1.Measure the Blue Reflectance Factor (R457) of samples. Blue Reflectance Factor is so calledÂ Blue Whiteness or ISO Brightness.
2.Analyze the sample to find out whether it contains any fluorescent brightener. If so, measure the fluorescent whiteness further, namely whitening rate.
3.Measure the opacity, transparency, light scattering coefficient and light absorbing co-efficient.
