CEN/TC 172/WG 9 - Gloss assessment
Establishment of two European prestandards in the field of gloss assessment of paper and board surfaces by means of reflectometer values, based on the DIN 54502: - One European prestandard which considers a 45° angle of incidencce - One European prestandard which considers a 75° angle of incidence.

General Information
This European Standard specifies a photometric test method for the assessment of visual gloss by means of a reflectometer value measured at an angle of 45°. It is applicable to plane paper and board surfaces of high gloss, commonly called glossy papers and boards, having reflectance values, measured according to this European Standard, above approximately 7. Materials containing optical brightning agents may be measured.

ISO 8254-2:2003 specifies a photometric test method for the assessment of visual gloss by means of a reflectometer value measured at an angle of 75 degrees. It is applicable to plane paper and board surfaces of low gloss, commonly called matt papers and boards having reflectance values, measured according to ISO 8254-2:2003, between 0 and approximately 20. Materials containing optical brightening agents may be measured.
