Paper -- Determination of transmittance by diffuse reflectance measurement
This standard has been revised by ISO 22891:2013
ISO 22891:2007 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. 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.
A standard is reviewed every 5 years
