Aluminium and aluminium alloys - Requirements for anodised products for use in contact with foodstuff

This European Standard specifies specific requirements for coloured or uncoloured anodic oxidation coatings on wrought and cast products in aluminium and aluminium alloys for use in contact with food.
These specific requirements cover the chemical composition of the bath, the sealing and the properties of the obtained anodic oxidation coatings. They do not cover dyestuffs and pigments but do cover the metallic deposits produced by electrolytic colouring.

Aluminium und Aluminiumlegierungen - Anforderungen an anodisierte Erzeugnisse, die in Kontakt mit Lebensmitteln kommen

Diese Europäische Norm legt die Anforderungen für gefärbte oder farblose anodisch erzeugte Oxidschichten auf Knet- und Gusserzeugnissen aus Aluminium und Aluminiumlegierungen für die Verwendung in Kontakt mit Lebensmitteln fest.
Diese Anforderungen umfassen die chemische Zusammensetzung des Bades, das Verdichten und die Eigenschaften der anodisch erzeugten Oxidschicht. Sie beinhalten nicht Tauch- und Pigmentfarb¬stoffe, aber beinhalten metallische Einlagerungen die durch elektrolytische Einfärbung erzeugt werden.

Aluminium et alliages d'aluminium - Spécifications pour les produits anodisés destinés à entrer en contact avec les aliments

La présente Norme européenne définit les spécifications particulières applicables aux couches anodisées colorées ou incolores déposées sur les produits corroyés ou moulés en aluminium et alliages d'aluminium, destinés à entrer en contact avec les aliments.
Ces spécifications particulières couvrent la composition chimique du bain, le colmatage et les propriétés des couches anodisées obtenues. Elles ne concernent ni les colorants ni les pigments.

Overview

EN 14392:2007 - Aluminium and aluminium alloys - Requirements for anodised products for use in contact with foodstuff (CEN) specifies safety and performance requirements for anodic oxidation (anodised) coatings on wrought and cast aluminium intended to contact food. The standard covers bath chemistry, sealing treatments and the properties of the resulting anodic oxide layers. It does not cover dyestuffs and pigments, but does cover metallic deposits produced by electrolytic colouring.

Key topics and technical requirements

• Scope: Applies to coloured and uncoloured anodic oxidation coatings on aluminium/aluminium alloys for food contact.
• Base material composition: Aluminium/alloy chemical composition must comply with EN 601 (castings) or EN 602 (wrought products) as applicable.
• Anodization bath chemistry: Anodizing must be performed in diluted aqueous solutions of one or more permitted acids, including:
  • sulfuric, sulfomaleic, sulfosalicylic, oxalic, sulfophthalic and phosphoric acids.
• Sealing:
  • Sealing of the anodic oxide is required unless the coating was produced in a bath containing only diluted phosphoric acid, or the anodised item will receive another coating prior to food contact.
  • Sealing must use distilled or demineralized water; appropriate additives are permitted but their identity and concentrations must comply with legal requirements and be declared on inspection certificates.
  • Technical parameters (temperature, pH, treatment duration, additive concentrations) must be chosen to minimize absorptive power, maximize chemical resistance and minimize migration of hazardous substances.
• Quality assurance and testing:
  • Manufacturers must implement a QA system enabling traceability of lots to relevant production parameters.
  • Routine control methods: EN 12373-4 (dye spot with prior acid treatment) and EN 12373-5 (admittance measurement).
  • Calibration method: EN 12373-7 (loss of mass after immersion in phosphoric/chromic acid with prior acid treatment).
• Conformity & documentation:
  • Inspection certificate type 3.1 per EN 10204 must be issued to certify compliance; frequency can be per-lot or periodic (not exceeding 12 months) unless otherwise agreed.
• Ordering: Order documents should reference EN 14392 and any requirements on inspection certificate periodicity.

Applications and users

• Manufacturers and processors of anodised aluminium cookware, food packaging, kitchenware, beverage containers and food-contact components.
• Anodizing plants, surface-treatment specialists and quality managers responsible for compliance, process control and traceability.
• Purchasers, specifiers, regulatory bodies and conformity assessors setting procurement specifications for aluminium articles intended for food contact.
