本文件描述了用于与食品接触的染色纸和纸板的测试程序。给出了两个程序。长期接触（例如食品包装）和短期接触方法B（例如餐巾，厨房用纸，家用纸）的程序A。 使用空白的视觉评估仅用于检测任何出血（是/否），而灰度评估提供了出血分级

This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Two procedures are given. Procedure A for contact of long duration (e. g. food packaging) and procedure B for contact of short duration (e. g. napkins, kitchen papers, household papers). Visual evaluation against a blank is used only in order to detect any bleeding (yes/no) while evaluation against a grey scale provides grading of the bleeding.
