TS 4791

TS 4791 is a terminology standard that brings together the basic terms used in the metallurgical industry and their definitions in a common technical language. Standards of this kind help prevent the same concept from being understood differently across production, quality control, engineering, and technical documentation, and they support consistency in plant operations, process names, product forms, and core manufacturing concepts.

Why metallurgy needs a dedicated terminology standard

Metallurgy spans a wide technical field, from extracting metal from ore to casting, forming, heat treatment, and the manufacture of finished products. The words used in this field vary with raw materials, semi-finished products, processes, equipment, and product types. Clear definitions create a shared understanding across technical drawings, specifications, training materials, and internal records. In general technical context, a terminology standard like this helps ensure that the name of a process, the class of a material, or a stage of manufacture is used with the same meaning every time.

What the standard covers

The stated scope is the basic terms and definitions related to the metallurgical industry. That means the document is focused on naming and defining concepts rather than setting product performance limits. In metallurgy, this kind of terminology framework helps keep expressions for processes such as melting, casting, rolling, annealing, and other manufacturing stages aligned with a single technical meaning.

• It is terminology-focused and defines basic terms.
• It applies to general usage in the metallurgical industry.
• It supports common understanding in production and technical communication.
• It defines concepts rather than product performance requirements.
