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.
