《GB/T 7973-2003纸、纸板和纸浆 漫反射因数的测定(漫射/垂直法)》由TC141(全国造纸工业标准化技术委员会)归口,主管部门为中国轻工业联合会。
本标准规定了测定纸、纸板和纸浆漫反射因数的基本条件,如仪器的光谱、几何和光度计特性以及标准量值的传递方法等。漫反射因数的测量可以求得以下光学性质:纸浆、纸及纸板的蓝光漫反射因数(蓝光亮度)、颜色、光散射和光吸收系数和纸的下透明度等。本标准适用于测定纸、纸板和纸浆。
Scope
This standard specifies the basic conditions for determining the diffuse reflectance factor of paper, cardboard and pulp, such as the spectral, geometric and photometric characteristics of the instrument and the transfer method of the standard value, etc. The measurement of diffuse reflection factor can obtain the following optical properties: blue light diffuse reflection factor (blue light brightness), color, light scattering and light absorption coefficient of pulp, paper and cardboard, opacity of paper, etc. This standard applies to the determination of paper, board and pulp.
