ISO 8254-2:2016规定了通过在75°角处测量反射计值来评估视觉光泽的光度试验方法。适用于光泽度低于65的平面纸和纸板表面,根据ISO 8254-2:2016进行测量。对于光泽度低于20的纸和纸板表面,应根据ISO 8254-2:2016进行测量,这是首选方法。可测量含有光学增白剂的材料。
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.
