TS EN 12597

TS EN 12597 is a terminology standard for bitumen and bituminous binders. It brings together the terms and definitions used for paving and industrial bitumens, as well as binders derived from bitumen, so that technical communication, specification writing and laboratory documentation can rely on a common vocabulary.

A controlled vocabulary for bitumen-related materials

The standard is aimed at materials within the scope of CEN/TC 336. In practical terms, that means bitumens and bituminous binders are the focus; non-petroleum hydrocarbon binders such as coal tar and its derivatives, and natural asphalts, are outside the core scope. Even so, some excluded materials and related terms are defined where they are needed to understand a product or process definition and to avoid ambiguity.

Why terminology matters in practice

A terminology document does not prescribe a test method or a product recipe. Instead, it clarifies how key concepts relate to each other: the base bitumen, modified or derived binders, application contexts, and the process language used around them. In the bitumen field, that distinction matters because binder behaviour is closely tied to temperature, handling, and performance in paving and industrial uses. Clear definitions help engineers, specifiers and laboratories use the same terms with the same meaning.

The value of TS EN 12597 lies in setting a clear boundary between in-scope and out-of-scope materials while supporting consistent technical language. It is especially useful wherever bituminous materials are described in standards, contracts, reports or product documentation, and where precision is needed to reduce misinterpretation.
