标准范围

ISO 5631-1:2009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。ISO 5631-1:2009不适用于含有荧光染料或颜料的彩色纸或纸板。可使用ISO/TC 6授权实验室提供的荧光参考标准（如ISO 2470-1所述），通过调整试样上照明的UV含量，使其符合CIE光源C中的UV含量，来确定含有荧光增白剂的纸张或纸板的颜色。

ISO 5631-1:2009 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.ISO 5631-1:2009 is not applicable to coloured papers or boards which incorporate fluorescent dyes or pigments. It may be used to determine the colour of papers or boards which 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 ISO/TC 6 authorized laboratory, as described in ISO 2470-1.
