Abstract

ISO 2470-1:2009 specifies a method for measuring the diffuse blue reflectance factor (ISO brightness) of pulps, papers and boards.

ISO 2470-1:2009 is limited in its scope to white and near-white pulps, papers and boards. The measurement can only be made in an instrument in which the ultraviolet energy level of the illumination has been adjusted to correspond to the CIE illuminant C using a fluorescent reference standard.
