TS EN 12258-1

TS EN 12258-1 is a terminology standard that gathers general terms and definitions for aluminium and aluminium alloys. Its purpose is to support a common technical language across the aluminium industry, especially when manufacturers, customers and other parties need to communicate about products and material concepts with precision.

Why general terms matter in aluminium practice

Aluminium technology spans casting, rolling, extrusion, heat treatment and surface finishing, so core words such as “aluminium”, “aluminium alloy” and related product descriptors must be used consistently. In general technical context, a terminology standard helps reduce ambiguity in specifications, purchase descriptions, technical documents and quality records, making it easier to identify exactly what material or product category is being discussed.

What this part covers

• General terms used for aluminium and aluminium alloy products.
• Vocabulary intended to facilitate communication with purchasers.
• A shared terminology base for product naming and technical documentation.
• Definitions and terms, not a test method or a requirements standard.

In a terminology standard, the value lies in conceptual clarity: names, definitions and relationships between terms are organised so that technical communication is less open to misunderstanding. This standard does not itself establish product performance limits or processing rules; it serves as a vocabulary reference for the aluminium sector. As a withdrawn document, it is best understood as a historical standard that may still be useful for reading older specifications and documents.
