Paper,board and pulps—Measurement of diffuse blue reflectance factor(ISO brightness)—Indoor daylight conditions


Standard in brief
Scope of Application:  
本标准规定了纸、纸板和纸浆蓝光漫反射因数(ISO亮度)在室内日光条件下的测定方法。本标准适用于白色和接近白色的纸、纸板和纸浆。测试含有荧光增白剂的试样时,使用荧光参比标准将仪器的紫外线(UV)辐射能量水平调整至与CIE照明体C一致的情况下才能进行测试。C光源具有一定比例的UV含量,相当于室内日光条件。注: D65亮度是通过将仪器调整至符合CIE标准照明体D65来测试的,该照明体的UV含量比本标准中规定的要高得多。D65亮度的测试方法标准为GB/T 7974。
