Resumen:
This document describes procedures for the testing of dyed paper and board intended to come into contact withfoodstuffs. Some procedures depending on the foreseeable use of the material are given.Visual evaluation against a grey scale provides grading of the bleeding.NOTE: For samples having significant different sides, a migration can occur from one glass fibre to the other andcould lead to wrong interpretation of the fastness of one side. These samples should be checked using largesampling procedure to prevent cross contamination of the glass fibre during the migration procedure. Theprocedure is described in annexe A. If lower limit of detection is required, this procedure could also be used.
