Paper. Determination of transmittance by diffuse reflectance measurement1 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. NOTE This means that, although this
