Paper and board intended to come into contact with foodstuffs - Determination of colour fastness of dyed paper and board

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.

Papier und Pappe vorgesehen für den Kontakt mit Lebensmitteln - Bestimmung der Farbechtheit von gefärbtem Papier und Pappe

Dieses Dokument legt ein Verfahren zur Prüfung von gefärbtem Papier und Pappe, die bestimmungsgemäß in
Kontakt mit Lebensmitteln kommen, fest. Es werden zwei Varianten angegeben: Verfahren A für langzeitigen
Kontakt (z. B. Lebensmittelverpackung) und Verfahren B für kurzzeitigen Kontakt (z. B. Servietten,
Küchentücher, Haushaltspapiere).
Visuelle Auswertung gegen eine Blindprobe wird nur durchgeführt, um ein generelles Ausbluten festzustellen
(ja/nein), während eine Auswertung gegen einen Graumaßstab eine Abstufung beim Ausbluten zulässt.

Papiers et cartons destinés a entrer en contact avec les denrées alimentaires - Détermination de la solidité de la couleur des papiers et cartons colorés

Le présent document décrit deux mode opératoires d’essai pour papiers et cartons colorés destinés a entrer
en contact avec les denrées alimentaires. Le mode opératoire A s’applique a ceux ayant un contact de longue
durée avec les denrées (emballage des aliments, par exemple) et le mode opératoire B a ceux ayant avec ces
dernieres un contact de courte durée (serviettes de table, papier essuie-tout, papiers a usage domestique, par
exemple).
L’examen visuel par rapport a un « blanc » n’est utilisé qu’afin de détecter un éventuel dégorgement (oui/non)
alors que l’évaluation par rapport a une échelle de gris permet un classement de celui-ci.
