标准摘要
[中文适用范围]： 本标准规定了消除镜面光泽度的漫反射法测量纸和纸板颜色的方法。 它可用于测定含有荧光增白剂的纸张或纸板的颜色，前提是测试件上的照明的紫外线含量已预先调整为使用荧光参考来给出与 CIE 标准光源 D65 相对应的校准色度值标准，并由授权实验室提供指定的 CIE 白度 (D65/10°) 值，如 ISO 11475 中所述。 本文件不适用于含有荧光染料或颜料的彩色纸或纸板。 [外文原描述]： This document specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. It can be used to determine the colour of papers or boards that contain fluorescent whitening agents, provided the UV content of the illumination on the test piece has been previously adjusted to give the calibrated colorimetric value corresponding to CIE standard illuminant D65, using a fluorescent reference standard with an assigned CIE whiteness (D65/10°) value provided by an authorized laboratory, as described in ISO 11475. This document is not applicable to coloured papers or boards that incorporate fluorescent dyes or pigments.
