scope:
This International Standard specifies a method for the calculation of transmittance based upon diffuse reflectance measurements. The use of the method is restricted to white and near-white translucent papers (see 3.9). If it is necessary to determine the transmittance of papers which contain fluorescent whitening agents, the fluorescence emission is eliminated using the prescribed UV cut-off filter.
