TS 5185 EN 23134-4

TS 5185 EN 23134-4 is a terminology standard for castings made of light metals and their alloys. It brings the vocabulary used for casting products into a common technical language, which helps reduce ambiguity in design, production, inspection, and commercial communication for aluminium and related light-metal castings.

What this casting vocabulary covers

The focus of this standard is the naming of terms and definitions used in the context of castings made from light metal alloys. A casting is generally understood as a part or semi-finished product formed by pouring molten metal into a mould and allowing it to solidify. In practice, light metals usually refers to low-density metal systems such as aluminium and magnesium alloys, and terminology standards like this are intended to keep those concepts consistent across technical use.

Why the distinctions matter

• A casting is the finished or semi-finished product obtained by the foundry process, not the raw metal or the alloy composition itself.
• Terminology standards help ensure that the same term is understood consistently in drawings, specifications, inspection records, and procurement documents.
• This part is focused on castings of light metals; it does not automatically cover terminology for castings made from other material families.

From a general engineering perspective, casting vocabulary supports consistent use of terms for part geometry, feeding arrangements, surface quality, defect names, and other core production concepts. This specific publication of TS 5185 EN 23134-4 organises the vocabulary for castings of light metals and their alloys, but it is not a process specification on its own and should not be read as defining test methods, tolerances, or acceptance limits.
