BS EN ISO 8254-2:2016规定了一种光度试验方法，用于通过以下方式评估视觉光泽: 以75°角测量的反射计值。适用于平面纸和纸板表面 光泽度低于65，根据ISO 8254的本部分进行测量。这应该是首选的方法 光泽度低于20的纸和纸板表面，根据ISO 8254的本部分进行测量。 可测量含有光学增白剂的材料。交叉引用:ISO 186ISO 187ISO 10110-5CIE 038-1977ISO 7944ISO 8254-1ISO 8254-3ISO/CIE 19476:2014CIE 15:2004CIE S017/E:2011CIE S013/E:2013EN 14086购买本文件时提供的所有当前修订版均包括在内。

BS EN 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 this part of ISO 8254. It should be the preferred method for paper and board surfaces of gloss levels below 20, measured according to this part of ISO 8254. Materials containing optical brightening agents may be measured.Cross References:ISO 186ISO 187ISO 10110-5CIE 038-1977ISO 7944ISO 8254-1ISO 8254-3ISO/CIE 19476:2014CIE 15:2004CIE S017/E:2011CIE S013/E:2013EN 14086All current amendments available at time of purchase are included with the purchase of this document.
