kSIST FprEN 14392:2026

kSIST FprEN 14392:2026 is the Slovenian version of prEN 14392:2026, a draft European Standard from CEN on anodised aluminium and aluminium alloys for food contact. It specifies requirements for coloured or uncoloured anodic oxidation coatings on wrought and cast products, so manufacturers, inspectors and buyers can check whether the bath, sealing and finished coating meet the document’s food-contact rules.

What does kSIST FprEN 14392:2026 specify?

kSIST FprEN 14392:2026 specifies requirements for anodised aluminium and aluminium alloy products intended to be in contact with food. It focuses on the coating process and the resulting anodic oxidation coating, not on decorative dye systems.

The document is organised into clauses on scope, normative references, terms and definitions, ordering information, material composition, anodization bath composition, sealing, and demonstration of conformity. It also includes one informative annex on national deviations.

What are the key requirements of kSIST FprEN 14392:2026?

kSIST FprEN 14392:2026 sets out the information needed at order stage, the permitted anodizing chemistry, how sealing is handled, and how conformity is demonstrated. In practice, it gives producers and purchasers a common basis for specifying food-contact anodised products and for checking that the process is controlled.

Ordering and product definition

Clause 4 says order documents need the standard number and any agreed requirement for the periodicity of inspection certificates. It also points back to EN ISO 7599 for the basic definition of the product and its properties, which helps buyer and supplier align on what is being ordered.

Base metal composition

Clause 5 requires the aluminium or aluminium alloy intended for anodising to comply with EN 601 or EN 602, as applicable. This matters because the base material must already be suitable for food-contact use before the anodic coating is applied.

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 tells the producer which bath chemistries are within the scope of the standard.

Sealing

Clause 7 says the anodic oxidation coating shall be sealed unless it was produced in a bath containing only diluted phosphoric acid, or unless another organic or inorganic coating will be applied before food contact. The sealing bath is distilled or demineralized water, with possible additives, and the inspection certificate has to confirm that the additives and their concentrations comply with current legal requirements.

Process control and quality assurance

Clause 7.3 requires the sealing parameters - especially temperature, pH, time, and additive type and concentration - to be chosen to reduce absorption, improve chemical resistance, and limit migration of potentially hazardous additives. Clause 7.4 requires a suitable quality assurance system, using EN ISO 2143 and EN ISO 2931 for routine control and EN ISO 3210 for calibration.

Conformity evidence

Clause 8 requires anodizing to take place within a quality assurance system that can trace a delivered lot back to the process parameters relevant to Clauses 5 to 7. The manufacturer must also issue an EN 10204 inspection certificate 3.1 confirming conformity, either per lot or periodically within a period not exceeding twelve months unless otherwise agreed.

What terms does kSIST FprEN 14392:2026 define?

kSIST FprEN 14392:2026 gives short definitions for the terms used in the standard so that suppliers and purchasers interpret them the same way.

• anodic oxidation coating - a coating made by an electrolytic oxidation process and used for protective, decorative or functional purposes.
• sealing - a post-anodising treatment that reduces porosity and absorption in the anodic oxide coating by hydrothermal processes.
• order document - the agreed ordering record between supplier and purchaser, including a confirmed order or a confirmed quotation.
• inspection certificate 3.1 - the EN 10204 certificate type required by Clause 8 to show compliance of delivered products.
• A-deviation - a national deviation caused by regulation, used in place of the European Standard’s provision in the affected country.
• QUALANOD - a named example of a recognized European quality label mentioned as a possible framework for quality assurance and assessment.

Who uses kSIST FprEN 14392:2026?

kSIST FprEN 14392:2026 is used by anodising companies, aluminium producers, quality assurance teams, inspection bodies and purchasers of food-contact aluminium products. It is relevant where coated wrought or cast aluminium parts need documented control of alloy composition, bath chemistry, sealing and traceability.

It is also useful for laboratories and certification schemes that check whether anodised products meet the document’s process and certificate requirements.

What changed in kSIST FprEN 14392:2026 from the previous edition?

kSIST FprEN 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 kSIST FprEN 14392:2026?

kSIST FprEN 14392:2026 names several referenced standards that supply the material, documentation and test framework around the anodising requirements.

What does the kSIST FprEN 14392:2026 document contain?

kSIST FprEN 14392:2026 contains the core requirements for ordering, material suitability, anodization bath chemistry, sealing, and conformity demonstration. It also includes the defined terms needed to read the standard consistently.

The informative annex gives an A-deviation note for France under Clause 7.1. For practical use, the document ties process control to inspection certificates and traceability, so it can support procurement specifications, production control and conformity checking.
