FprEN 14392

• Abstract:

  This document specifies 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 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.

Overview

FprEN 14392 is a draft European Standard developed by CEN for specifying requirements for anodised aluminium and aluminium alloy products in contact with foodstuff. The standard addresses the properties and processing of coloured or uncoloured anodic oxidation coatings applied to wrought and cast aluminium products intended for food contact applications. Its primary focus is to ensure safety, durability, and suitability of anodised aluminium surfaces by regulating aspects such as the chemical composition of the anodising bath, sealing procedures, and coating characteristics. This standard is fundamental for manufacturers, suppliers, and users seeking to comply with European regulations on materials intended to come into contact with food.

Key Topics

• Scope and Purpose
  The standard outlines requirements for anodic oxidation coatings, both coloured and uncoloured, on aluminium and aluminium alloy products used with food.
  It excludes requirements related to dyes or pigments, but covers metallic deposits from electrolytic colouring.

• Chemical Composition Requirements

  • Specifies suitable aluminium alloys based on EN 601 (castings) and EN 602 (wrought products).
  • Defines permitted acids in the anodising process, including sulfuric, sulfomaleic, sulfosalicylic, oxalic, sulfophtalic, and phosphoric acids.

• Sealing and Quality Control

  • Mandates sealing of anodic coatings to enhance durability and chemical resistance, except in specific cases (e.g., certain phosphoric acid baths).
  • Details composition requirements for the sealing bath, emphasizing the importance of distilled or demineralized water and compliant additives.
  • Stipulates tight control and documentation of parameters such as temperature, pH, treatment time, and additive concentrations.

• Documentation and Traceability

  • Requires effective quality assurance processes, including batch traceability and adherence to inspection protocols (e.g., EN 10204 certificate "3.1").
  • Orders must reference the standard and specify needs for inspection certification periodicity.

• Conformity and Assessment

  • Manufacturers must provide inspection certificates and document conformity to the defined requirements.
  • Quality assessments may reference recognized schemes such as QUALANOD.

Applications

• Food Processing Equipment
  Anodised aluminium components in food processing lines, filling machines, and preparation tools benefit from enhanced corrosion resistance and food safety.

• Food Packaging and Containers
  Used for storage vessels, trays, and utensils intended for repeated contact with different foodstuffs.

• Kitchenware and Domestic Items
  Includes items such as cookware, bakeware, serving dishes, and cutlery, where anodised surfaces prevent contamination and simplify cleaning.

• Catering and Industrial Food Service
  Equipment such as trolleys, display counters, and storage bins often utilize anodised aluminium due to its robustness and compliance with hygiene standards.

By complying with FprEN 14392, manufacturers ensure their anodised aluminium products are safe for food contact, resistant to corrosion, and meet European regulatory requirements.
