标准摘要
[中文适用范围]： ISO 8254 的本部分规定了一种光度测试方法，用于通过以 75° 角测量的反射仪值来评估视觉光泽度。该方法适用于根据 ISO 8254 的本部分测量的光泽度低于 65 的平面纸张和纸板表面。对于根据 ISO 8254 的本部分测量的光泽度低于 20 的纸张和纸板表面，该方法应为首选方法。含有荧光增白剂的材料也可以进行测量。 [外文原描述]： 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.
