本文件描述了测试与食品接触的荧光增白纸和纸板牢度的程序。给出了根据可预见的材料使用的一些程序。 评估在紫外光下玻璃纤维纸的荧光的视觉缺失。 对于具有显着不同侧面的样品，可能会发生从一个玻璃纤维到另一个玻璃纤维的迁移，并可能导致错误的解释一面的牢度。这些样品应使用大量采样程序进行检查，以防止玻璃纤维在迁移过程中交叉污染。该程序在附录A中描述。如果需要检测下限，也可以使用该程序

This document describes procedures for the testing of the fastness of fluorescent whitened paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given. Visual absence of the glass fibre paper’s fluorescence under UV light is evaluated. For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. It is advisable to check these samples using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in Annex A. If lower limit of detection is required, this procedure can also be used.
