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. Some procedures depending on the foreseeable use of the material are given.
Visual evaluation against a grey scale provides grading of the bleeding.
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 could also be used.

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 für den Kontakt mit Lebensmitteln bestimmt sind, fest. Es werden verschiedene Varianten angegeben, je nach vorher¬sehbarer Nutzung des vorhandenen Werkstoffs.
Die visuelle Bewertung gegen einen Graumaßstab gibt Abstufungen beim Ausbluten vor.
Bei Proben mit wesentlich unterschiedlichen Seiten kann es zu einer Migration von einer Glasfaser zur anderen kommen, was wiederum zur falschen Interpretation der Farbechtheit auf einer Seite führen könnte. Es ist empfehlenswert, diese Proben im großen Probenahmeverfahren zu prüfen, um eine Querkontamination der Glasfasern während des Migrationsvorgangs zu vermeiden. Das Verfahren ist in Anhang A beschrieben. Wenn niedrigere Nachweisgrenzen gefordert sind, könnte dieses Verfahren ebenfalls zur Anwendung kommen.

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

Le présent document décrit les modes opératoires d’essai pour papiers et cartons colorés destinés à entrer en contact avec les denrées alimentaires. Plusieurs modes opératoires selon l’utilisation prévisible du matériau sont décrits.
L’examen visuel par rapport à une échelle de gris permet un classement du dégorgement.
Pour les échantillons dont les faces sont sensiblement différentes, une migration peut se produire d’une fibre de verre à l’autre et peut conduire à une mauvaise interprétation de la solidité d’une face. Il est recommandé de vérifier ces échantillons à l’aide d’un mode opératoire d’échantillonnage utilisant des échantillons de grande taille afin d’empêcher la contamination croisée de la fibre de verre au cours de la procédure de migration. Le mode opératoire est décrit à l’Annexe A. Si une limite de détection inférieure est requise, ce mode opératoire peut également être utilisé.

Papir, karton in lepenka, namenjeni za stik z živili - Ugotavljanje obstojnosti barve v obarvanem papirju, kartonu in lepenki

Ta dokument opisuje postopke za preskušanje barvanega papirja in kartona, namenjenega za neposreden stik z živili. Podani so nekateri postopki, odvisni od predvidene uporabe materiala. Vizualna ocena na lestvici sivih tonov omogoča razvrščanje izločljivosti. OPOMBA: Pri vzorcih, katerih strani se precej razlikujejo, lahko pride do prehajanja iz enega steklenega vlakna v drugega, kar lahko privede do napačnega prepoznavanja obstojnosti ene strani. Te vzorce je treba pregledati s postopkom velikega vzorčenja, da se prepreči navzkrižna kontaminacija steklenih vlaken med postopkom prehajanja. Postopek je opisan v dodatku A. Če je potrebna spodnja meja zaznavanja, se lahko uporabi tudi ta postopek.
