标准范围

ISO 5631-2:2008规定了一种通过消除镜面光泽的漫反射法测量纸和纸板颜色的方法。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/TC 6授权实验室提供的指定CIE白度（D65/10°）值的荧光参考标准，将试样上照明的UV含量调整为符合CIE标准光源D65中的UV含量，如ISO 11475所述。ISO 5631-2:2008不适用于含有荧光染料或颜料的彩色纸或纸板。

ISO 5631-2:2008 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.It 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 standard illuminant D65, using a fluorescent reference standard with an assigned CIE whiteness (D65/10°) value provided by an ISO/TC 6 authorized laboratory, as described in ISO 11475.ISO 5631-2:2008 is not applicable to coloured papers or boards that incorporate fluorescent dyes or pigments.
