DIN EN 646:2006 Paper and board intended to come into contact with foodstuffs - Determination of colour fastness of dyed paper and board; German version EN 646:2006
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.
