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.

Overview

EN 12498:2018 (CEN) specifies a laboratory test method for the determination of cadmium (Cd), lead (Pb) and chromium (Cr) in an aqueous extract of paper and board intended to come into contact with food. The standard applies where extractable metal contents exceed 0.1 mg/kg (Cd), 0.6 mg/kg (Pb) and 0.25 mg/kg (Cr), though lower levels can be measured with very sensitive equipment and trace-element laboratory conditions. EN 12498:2018 supersedes EN 12498:2005 and adds chromium to the scope.

Key topics and technical requirements

• Extraction methods: Uses stabilized cold water extract (EN 645) or hot water extract (EN 647) as the sample matrix.
• Analysis principle: Determination by atomic absorption spectrometry with a graphite tube furnace (GFAAS). ICP may be used if validated.
• Reagents and standards:
  • Nitric acid and hydrochloric acid in specified dilutions.
  • Multi-element or single-element stock solutions (e.g., 1 000 mg/L).
  • Matrix modifiers such as ammonium dihydrogen phosphate, palladium nitrate, magnesium nitrate.
  • High-purity gases (nitrogen/argon) and trace-element–grade water.
• Instrumental details:
  • Calibration: at least 3 calibration points covering measurement range; calibration blank required.
  • Optional use of standard addition for matrix effects.
  • Suggested spectrometer wavelengths: Cd 228.8 nm, Pb 217.0 nm or 283.3 nm (preferred), Cr 357.9 nm.
• Quality and reporting:
  • Blank determination is mandatory (use water and reagents) and must be subtracted.
  • Results expressed in mg/kg (or mg/dm of extract); laboratories should use certified reference materials and monitor contamination sources.
  • Test report must reference EN 12498:2018 and include extraction method, sample ID, dates, blank info, results and any deviations.

Applications and users

This standard is used for compliance testing and quality control of food-contact paper and board. Typical users:

• Accredited analytical laboratories performing heavy-metal testing.
• Paper, carton and packaging manufacturers for product safety verification.
• Food packaging converters and brand owners ensuring regulatory compliance.
• Regulatory bodies and conformity assessment organizations monitoring food-contact materials.

Related standards

• EN 645 - Preparation of a cold water extract (paper and board for food contact)
• EN 647 - Preparation of a hot water extract (paper and board for food contact)
• EN 12498:2005 - Superseded version (chromium added in 2018)
