标准范围

本文件规定了使用纸背衬通过漫反射法仪器测定薄纸或薄纸产品不透明度的测试程序。本文件包含单层和多层产品试件制备的具体说明，其中可能需要特殊的制备/程序。它可用于测定含荧光增白剂的薄纸和薄纸产品的不透明度，条件是入射在测试件上的辐射的UV含量已使用由授权实验室提供的荧光参考标准进行调整，以符合CIE光源C中的UV含量，如ISO 2470-1中所述。

This document specifies the testing procedures for the instrumental determination of the opacity of tissue paper or tissue products by diffuse reflectance using a paper backing.

This document contains specific instructions for the preparation of test pieces of single-ply and multi-ply products, where special preparation/procedures might be necessary.

It can be used to determine the opacity of tissue paper and tissue products containing fluorescent whitening agents, provided the UV content of the radiation incident on the test piece has been adjusted to conform to that in the CIE illuminant C using a fluorescent reference standard provided by an authorized laboratory as described in ISO 2470-1.
