Paper and board -- Determination of opacity (paper backing) -- Diffuse reflectance method
This International Standard specifies a method for the determination of the opacity (paper backing) of paper by diffuse reflectance.
It is restricted to white and near-white papers (and boards). Paper or board that has been treated with a fluorescent dyestuff or exhibits significant fluorescence may be measured, but the agreement between values obtained with different instruments may be unsatisfactory and there may be difficulty in assessing the meaning of results.
