标准范围

ISO 5631-3:2008规定了通过消除镜面光泽的漫反射法测量纸和纸板颜色的方法。ISO 5631-3:2008主要用于测量图形艺术行业中使用的纸张和纸板的颜色，该行业根据ISO 13655规定了D50/2°条件下的颜色测量。该方法可用于测定含有荧光增白剂的纸张或纸板的颜色，前提是已使用ISO 2470-1中所述的授权实验室提供的荧光参考标准，将试样上照明的UV含量调整为符合CIE光源C中的UV含量。ISO 5631-3:2008不适用于含有荧光染料或颜料的彩色纸或纸板。

ISO 5631-3:2008 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.ISO 5631-3:2008 is primarily intended for measuring the colour of paper and board to be used in the graphic arts industry where that industry specifies the measurement of colour under D50/2° conditions in accordance with ISO 13655.The method may 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 adjusted to conform to that in the CIE illuminant C, using a fluorescent reference standard provided by an authorized laboratory, as described in ISO 2470-1.ISO 5631-3:2008 is not applicable to coloured papers or boards that incorporate fluorescent dyes or pigments.
