Paper and board - Paper and board intended to come into contact with foodstuffs - Determination of cadmium, chromium and lead in an aqueous extract

This document is one in a series of Standards for the determination of heavy metals in an aqueous extract of paper or board intended for contact with food. This document specifies the test method for the determination of cadmium, lead and chromium in an aqueous extract.
It is applicable to paper and paperboard with extractable metal contents exceeding
-   0,1 mg per kg for cadmium,
-   0,6 mg per kg for lead,
-   0,25 mg per kg for chromium.
Metal content levels below those given can be measured by this document if very sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.

Papier und Pappe - Papier und Pappe für den Kontakt mit Lebensmitteln - Bestimmung von Cadmium, Chrom und Blei in einem wässrigen Extrakt

Dieses Dokument ist Bestandteil einer Reihe von Normen, die die Bestimmung von Schwermetallen in wässrigen Extrakten aus Papier oder Pappe, die in Kontakt mit Lebensmitteln kommen, festlegen. Dieses Dokument legt ein Prüfverfahren zur Bestimmung von Cadmium, Blei und Chrom in einem wässrigen Extrakt fest.
Sie ist anwendbar auf Papier und Pappe mit extrahierbaren Metallgehalten, die folgende Werte überschreiten:
-   0,1 mg je kg bei Cadmium;
-   0,6 mg je kg bei Blei;
-   0,25 mg je kg bei Chrom.
Metallgehalte, die unterhalb der oben genannten liegen, können mit diesem Dokument gemessen werden, wenn eine sehr empfindliche Laborausstattung vorhanden ist und alle anderen Laborbedingungen die Anforderungen für die Spurenelementanalyse erfüllen.

Papier et carton - Papiers et cartons destinés à entrer en contact avec les denrées alimentaires - Détermination du cadmium, du chrome et du plomb dans un extrait aqueux

Le présent document fait partie d’une série de normes pour la détermination des métaux lourds dans un extrait aqueux de papier ou de carton destiné à entrer en contact avec les denrées alimentaires. Le présent document spécifie la méthode d’essai pour le dosage du cadmium, du plomb et du chrome dans un extrait aqueux.
Il est applicable aux papiers et cartons avec des teneurs en métaux lourds extractibles dépassant :
-   0,1 mg/kg pour le cadmium ;
-   0,6 mg/kg pour le plomb ;
-   0,25 mg/kg pour le chrome.
Des teneurs en métaux inférieures aux valeurs indiquées ci-dessus peuvent être mesurées en suivant le présent document si un appareillage très sensible est disponible et si toutes les autres conditions dans le laboratoire satisfont aux exigences de l’analyse des éléments à l’état de traces.

Papir, karton in lepenka - Papir, karton in lepenka v neposrednem stiku z živili - Določevanje kadmija, kroma in svinca v vodnem ekstraktu

Ta evropski standard spada v skupino standardov za določanje težkih kovin v vodnem ekstraktu papirja ali kartona, namenjenega za neposreden stik z živili. Ta evropski standard določa preskusno metodo za določanje kadmija, svinca in kroma v vodnem ekstraktu.
Uporablja se za papir, karton in lepenko z vsebnostjo izločljivih kovin, ki presega:
– 0,02 mg/kg za kadmij;
– 0,15 mg/kg za svinec;
– 0,05 mg/kg za krom.
Ravni vsebnosti kovin pod navedenimi se lahko izmerijo s tem evropskim standardom, če je na voljo zelo občutljiva oprema in če vsi drugi laboratorijski pogoji izpolnjujejo zahteve za analizo elementov v sledovih.
