ISO 8254-2:2016 specifies a photometric test method for the assessment of visual gloss by means of a reflectometer value measured at an angle of 75°. It is applicable to plane paper and board surfaces of gloss levels below 65, measured according to ISO 8254-2:2016. It should be the preferred method for paper and board surfaces of gloss levels below 20, measured according to ISO 8254-2:2016. Materials containing optical brightening agents may be measured.
