This International Standard specifies a method for the calculation of light scattering and light absorption coefficients based upon diffuse reflectance measurements.
The use of the method is restricted to white and near-white uncoated papers with an opacity less than about 95 %. Paper that has been treated with a fluorescent dyestuff or exhibits significant fluorescence can only be dealt with if a filter with a cut-off wavelength of 420 nm is used to eliminate all the fluorescence effect.
