EN 14392:2026

• 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.

EN 14392:2026 is a draft European Standard from CEN for anodised products of aluminium and aluminium alloys intended for contact with food. It specifies the requirements for the anodic oxidation coating, the anodization bath, sealing, and conformity documentation for wrought and cast products. It is prepared by CEN/TC 132 and is intended to replace EN 14392:2007.

What does EN 14392:2026 specify?

EN 14392:2026 sets requirements for coloured or uncoloured anodic oxidation coatings on aluminium and aluminium alloy products used in contact with food. The document focuses on the coating process and the resulting coating properties, not on the general design of the article.

The scope also makes clear what is covered and what is not: the bath chemistry, sealing, and the coating properties are in scope, while dyestuffs and pigments are not. Metallic deposits produced by electrolytic colouring are covered.

The document is organized into:

• Clause 1 Scope
• Clause 2 Normative references
• Clause 3 Terms and definitions
• Clause 4 Ordering information
• Clause 5 Chemical composition of the aluminium or aluminium alloy
• Clause 6 Chemical composition of the anodization bath
• Clause 7 Sealing, with subclauses on general rules, bath composition, process parameters, and quality assurance
• Clause 8 Demonstration of conformity
• Annex A, which gives A-deviations

What are the key requirements of EN 14392:2026?

EN 14392:2026 ties together the base material, the anodizing bath, sealing, and quality documentation. In practice, this means a producer has to control the full process chain, not just the finished surface.

Base aluminium or aluminium alloy

Clause 5 requires the aluminium or aluminium alloy intended for anodising in food contact use to comply with EN 601 or EN 602, as applicable. This means the starting material must already meet the chemical composition rules for the product type.

Anodization bath

Clause 6 limits anodization to a diluted aqueous solution of one or more named acids: sulfuric, sulfomaleic, sulfosalicylic, oxalic, sulfophthalic, or phosphoric acid. This gives manufacturers a defined process chemistry and narrows the bath formulation used for food-contact applications.

Sealing of the anodic oxidation coating

Clause 7.1 requires sealing unless the coating was produced in diluted phosphoric acid only, or unless another organic or inorganic coating will be applied before the product is used in contact with food. In practice, the sealing step is part of controlling the coating’s porosity and absorption.

Clause 7.2 says sealing is done in distilled or demineralized water, with appropriate additives if used. The inspection certificate must confirm that the additives and their concentrations comply with current legal requirements.

Clause 7.3 requires the sealing process parameters, especially temperature, pH, treatment time, and additive type and concentration, to be chosen to reduce absorbency, improve chemical resistance, and minimize migration of potentially hazardous additives. That makes process control a compliance issue, not only a production preference.

Quality assurance and conformity

Clause 7.4 requires the producer to establish a suitable quality assurance system for sealing control. Routine control uses EN ISO 2143 and EN ISO 2931, while EN ISO 3210 is used for calibration.

Clause 8 requires anodizing to be carried out within a quality assurance system that can trace each delivered lot back to the relevant production parameters from Clauses 5 to 7. The manufacturer must also issue an inspection certificate "3.1" according to EN 10204, either for each lot or periodically, as agreed, for a period not exceeding twelve months.

Ordering information

Clause 4 requires order documents to identify this document and to state any requirement for the periodicity of inspection certificates. This is the point where buyer and supplier agree how compliance evidence will be supplied.

What terms does EN 14392:2026 define?

• Anodic oxidation coating - A coating formed by an electrolytic oxidation process, with protective, decorative, or functional properties.
• Sealing - A treatment after anodising that reduces porosity and absorption by hydrothermal processes.
• Order document - The document or set of documents agreed between supplier and purchaser when ordering.
• Inspection certificate "3.1" - The conformity document required by Clause 8 and issued according to EN 10204.
• Quality assurance system - The controlled system the producer uses to monitor sealing quality and traceability through the process.

Who uses EN 14392:2026?

EN 14392:2026 is used by anodising companies, aluminium product manufacturers, suppliers, purchasers, and quality assurance staff working on food-contact products. It is relevant to producers of wrought and cast aluminium and aluminium alloys, and to laboratories or inspection teams checking bath chemistry, sealing performance, and conformity records.

It is also useful for buyers who need to specify food-contact anodised products in purchase documents and for auditors who check traceability and inspection certificates.

What changed in EN 14392:2026 from the previous edition?

EN 14392:2026 supersedes EN 14392:2007. The foreword states one significant technical change: withdrawn EN normative references have been replaced by EN ISO replacing documents.

Which standards are used with EN 14392:2026?

• EN 601 - Gives the chemical composition requirements for cast aluminium products used in contact with foodstuff.
• EN 602 - Gives the chemical composition requirements for wrought semi-finished aluminium products used to make food-contact articles.
• EN 10204 - Provides the inspection certificate type "3.1" used for conformity documentation.
• EN 12258-1 - Supplies general aluminium terms and definitions used in Clause 3.
• EN ISO 7599 - Is used in Clause 4 for defining the product and its properties in the order document.
• EN ISO 2143 and EN ISO 2931 - Are used for routine control of sealing quality.
• EN ISO 3210 - Is used for calibration purposes in sealing quality assessment.

What does the EN 14392:2026 document contain?

EN 14392:2026 contains the specification for anodised aluminium products for food contact, plus the process and documentation rules needed to demonstrate conformity. It includes clauses on ordering, base-metal composition, anodization bath chemistry, sealing, and quality assurance.

The document also includes references to the control methods used to check sealing quality and a conformity clause that requires traceability and an EN 10204 3.1 certificate. Annex A gives informative A-deviations, including the French deviation listed in the text.
