英文名称：Paper, board and pulps — Measurement of diffuse radiance factor (diffuse reflectance factor)

发布日期：2024-03

标准范围

本文件描述了测量所有类型的纸浆、纸和纸板的漫射辐射系数的一般程序。更具体地说，它详细规定了用于校准设备的程序，并在附件？a、用于此类测量的设备的特性。本文件可用于测量含有荧光增白剂的材料的漫射辐射因子和相关性质，前提是根据描述所讨论性质的测量的国际标准，仪器照明的UV含量已被调节以给出与所选CIE光源的荧光参考标准相同的荧光水平。附件？C描述了荧光参考标准的制备。

This document describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail the procedures to be used for calibrating the equipment, and in Annex A, the characteristics of the equipment to be used for such measurements.

This document can be used to measure the diffuse radiance factors and related properties of materials containing fluorescent whitening agents, provided that the UV-content of the instrument illumination has been adjusted to give the same level of fluorescence as a fluorescent reference standard for a selected CIE illuminant, according to the International Standard describing the measurement of the property in question.

Annex C describes the preparation of fluorescent reference standards.
