DIN EN 10335 2005-07 PDF

Full title and description

STB DIN EN 10335:2005-07 — Steel for packaging — Flat steel products intended for use in contact with foodstuffs, products or beverages for human and animal consumption — Non-alloyed electrolytic chromium / chromium‑oxide coated steel. This designation indicates the European Standard EN 10335:2005 as adopted by DIN (German national adoption) and presented in the STB cataloging/translation variant cited by some national bodies.

Abstract

EN 10335:2005 specifies the required base steel composition and the composition and characteristics of the metallic chromium / chromium‑oxide coating used for lacquered electrolytic chromium/chromium‑oxide coated steel intended for direct contact with food and feed. Typical applications include drink cans, food cans, closures and ends. The standard covers material definition, coating requirements, surface treatment (including oiling), dimensional and marking/traceability information and inspection/acceptance rules for packaging-grade chromium‑coated sheet.

General information

• Status: Originally published 2005; national adoptions exist (DIN/other). The 2005 edition has been maintained in national catalogs and in some countries later superseded by a revised EN (see scope/FAQ for current revision notes).
• Publication date: 2005-07 (EN 10335:2005 — July 2005 national adoption notation).
• Publisher: CEN (European Committee for Standardization); national adoption/reference as DIN EN 10335 (Deutsches Institut für Normung) and in some catalogs under STB naming.
• ICS / categories: 67.250 — Materials and articles in contact with foodstuffs; also relevant ICS 77.140.50 (flat steel products).
• Edition / version: EN 10335:2005 (nationally published as DIN EN 10335:2005-07 / STB variant). Note: later European revisions to EN 10335 were published in the 2024–2025 timeframe; check your national standards body for the current valid edition.
• Number of pages: Varies by national publication and language (typical EN PDF/text runs in the order of 7–13 pages depending on forewords and annexes).

Scope

This standard applies to flat steel products intended for manufacturing lacquered articles which, as finished products, are intended for direct contact with foodstuffs or beverages for human or animal consumption. It defines the base steel grades appropriate for packaging, the composition and required properties of the electrolytic chromium / chromium‑oxide coating (used as a corrosion-resistant base for lacquer), surface preparation and oiling, dimensional and tolerance requirements, purchaser information to be supplied on order, inspection and marking/traceability requirements. It does not apply to steels for uses outside packaging in contact with food.

Key topics and requirements

• Definition of base steel chemical composition limits and acceptable grades for packaging use.
• Composition and microstructure requirements for electrolytic chromium / chromium‑oxide (duplex) coating intended for lacquered food packaging.
• Surface treatment and handling requirements including acceptable oiling and provisions for food‑contact‑compatible oils.
• Dimensional requirements and tolerances for sheet and coils of packaging steel.
• Inspection and test requirements (coating weight/thickness, adhesion, visual and functional checks as appropriate).
• Designation, marking, labelling and traceability requirements for coils, bundles and delivered items.
• Ordering information: purchaser-specified requirements, tolerances, surface finish and certification/inspection options.

Typical use and users

Main users include steel producers and processors producing packaging sheet, can manufacturers and converters (beverage and food can producers), lacquer/coating formulators, procurement/specification engineers in the food packaging industry, quality and regulatory teams responsible for food-contact materials, and testing/inspection laboratories that verify conformity with packaging‑grade metal standards.

Related standards

Standards commonly referenced with EN 10335 include EN 10202 (cold‑reduced tinmill products — dimensions, coatings and oiling), EN 10333 (tinplate for food contact), EN 10334 (blackplate and related packaging steels), and other EN/DIN product family standards covering coated strip and plate such as EN 10326/10327. National adoptions (DIN EN, BS EN, NF EN, etc.) and later EN revisions should be consulted for cross‑references and up‑to‑date normative references.

FAQ

Q: What is this standard?

A: EN 10335:2005 (published as DIN EN 10335:2005-07 in German adoption and sometimes cataloged as STB DIN EN 10335 2005-07) is a European product standard that defines the base steel and electrolytic chromium/chromium‑oxide coating requirements for flat steel products intended for direct contact with foodstuffs and beverages (used for canned food, beverage cans, closures, etc.).

Q: What does it cover?

A: It covers base metal composition limits, the chemistry and basic properties of the chromium/chromium‑oxide coating used before lacquering, surface treatment (including oiling), dimensional tolerances, inspection/acceptance rules, designation and marking/traceability, and the information purchasers must provide when ordering packaging steel.

Q: Who typically uses it?

A: Steel mills and strip producers, can and closure manufacturers, coating suppliers and lacquer formulators, quality and regulatory engineers in the food-packaging supply chain, procurement teams specifying food-contact materials, and testing labs validating conformity.

Q: Is it current or superseded?

A: The 2005 edition is the original EN 10335:2005. National adoptions may still reference that edition or show it as withdrawn or superseded. CEN has issued later revisions to the EN 10335 family (a revised EN was published in the 2024–2025 timeframe). Always confirm the currently valid edition for your country with your national standards body (DIN, BSI, AFNOR, ANSI mirror catalogs, etc.) before making procurement or compliance decisions.

Q: Is it part of a series?

A: Yes. EN 10335 is part of a family of European standards covering steels for packaging (for example EN 10333 for tinplate, EN 10334 for blackplate, and related EN/DIN standards governing coated strip and packaging‑grade steels). These standards collectively address different coatings, base metals and product-types used in food-contact packaging.

Q: What are the key keywords?

A: Key terms to search or use when specifying material: chromium coated steel, chromium‑oxide coating, electrolytic chromium, lacquered packaging steel, food contact materials, packaging sheet, DIN EN 10335, EN 10335:2005 (or EN 10335 revised edition).
