标准范围

本文件规定了一种通过消除镜面光泽的漫反射法测量纸张和纸板颜色的方法。它可用于测定含有荧光增白剂的纸张或纸板的颜色，前提是已事先调整试件上照明的UV含量，以给出与CIE？相对应的校准比色值标准光源D65，使用具有指定CIE的荧光参考标准白度（D65/10°）值由授权实验室提供，如ISO11475本文件不适用于含有荧光染料或颜料的彩色纸或纸板。

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.
