ISO 11476:2016规定了用于测定纸张和纸板CIE白度的程序，以获得与白纸和纸板在室内观看时的视觉外观相对应的值，无论是否使用荧光增白剂。它基于在整个可见光谱范围（VIS）内获得的辐射系数数据，而ISO亮度的测量仅限于VIS的蓝色区域。它还规定了测定CIE色度值和CIE白度荧光成分的程序。 此外，由于存在荧光增白剂时获得的结果取决于UV，因此其规定了调整UV含量的方法，以对应于CIE光源C的UV含量[10][12]- 落在样品上的辐射含量。CIE光源C被视为室内照明条件的代表，因为它包含适当比例的紫外线辐射。[7] 此方法不适用于含有荧光染料的彩色纸张。这是特定于荧光出现在可见光谱范围蓝色区域的情况。 ISO 11476:2016与ISO 2469一起阅读。

ISO 11476:2016 specifies the procedure to be used for determining the CIE whiteness of papers and boards, in order to obtain values which correspond to the visual appearance of white papers and boards, with or without fluorescent whitening agents, when they are viewed indoors. It is based on radiance factor data obtained over the full visible spectral range (VIS) in contrast to the measurement of ISO brightness, which is limited to the blue region of VIS. It also specifies the procedures for the determination of CIE tint values and the fluorescent component of CIE whiteness. In addition, it specifies a method for adjustment of the UV-content to correspond to that of CIE illuminant C,[10][12] since the results obtained when fluorescent whitening agents are present are dependent upon the UV-content of the radiation falling upon the sample. The CIE illuminant C is taken to be representative of indoor illumination conditions because it contains a suitable proportion of UV radiation.[7] This method is not applicable to coloured papers containing fluorescent dyes. It is specific to the situation where the fluorescence occurs in the blue region of the visible spectral range. ISO 11476:2016 is read in conjunction with ISO 2469.
