Paper, board and pulps - Measurement of diffuse blue reflectance factor (ISO brightness)

BS ISO 2470-2000 发布历史

This International Standard specifies a method for measuring the diffuse blue reflectance factor (ISO brightness) of pulps, papers and boards. This International Standard is limited in its scope to white and near-white pulps, papers and boards. Materials exhibiting fluorescence which promotes the appearance of whiteness may be measured but the ultraviolet energy level of the illumination must be adjusted using a fluorescent calibration standard if standardization and agreement between instruments is to be achieved. NOTE A brightness value associated with an instrument setting adjusted to conform to the CIE standard illuminant D65 (cf. ISO 11475), which has a much higher UV-content than the CIE illuminant C specified in this International Standard, is outside the scope of this International Standard and consequently is not "ISO brightness". Such a property may be called "D65 brightness".
