ISO 9416:2017规定了一种计算光散射和光吸收系数的方法，该方法基于在ISO 2469规定的条件下使用配色函数进行的漫反射测量？(λ)和CIE光源C。需要强调的是，光散射和光吸收系数的严格评估需要使用本文指定的仪器无法实现的条件。通过应用本文件获得的值取决于Kubelka-Munk方程的应用，不是全反射数据，而是使用指定的d/0°几何形状和光泽阱获得的反射因子数据。该方法的使用仅限于不透明度小于约95%的白色和接近白色的未涂布纸。已用荧光染料处理过的纸张或显示出显著荧光的纸张，只有在带有切口的过滤器-420nm的off波长用于消除UVex(420)模式中的所有荧光效应。

ISO 9416:2017 specifies a method for the calculation of light-scattering and light-absorption coefficients based upon diffuse reflectance measurements made under the conditions specified in ISO 2469 using the colour matching function ？(λ) and CIE illuminant C.It is emphasized that the strict evaluation of the light-scattering and light-absorption coefficients requires conditions which cannot be achieved with the instrumentation specified here. The values obtained by application of this document are dependent on the application of the Kubelka-Munk equations, not to full reflectance data but to reflectance factor data obtained using the specified d/0° geometry and a gloss trap.The use of the method is restricted to white and near-white uncoated papers with an opacity less than about 95 %. Paper that has been treated with a fluorescent dyestuff or that exhibits significant fluorescence can only be dealt with if a filter with a cut-off wavelength of 420 nm is used to eliminate all the fluorescence effect in the UVex(420) mode.
