TS EN 12597

TS EN 12597 is a terminology standard that establishes the terms and definitions used in the field of bitumen and bituminous binders. In practice, a shared vocabulary matters whenever these materials are specified, traded, tested, or discussed in technical documents, because the same word can otherwise be used for different material forms or process-related concepts. This standard focuses on naming and defining concepts rather than setting material performance requirements.

What the terminology set covers, and what it leaves out

According to its scope, the standard is limited to bitumens and bituminous binders within the remit of CEN/TC 336. It does not extend to non-petroleum hydrocarbon binders such as coal tar and its derivatives, nor to natural asphalts. Even so, it includes some terms for excluded materials and related concepts where those terms are needed to understand a product or process definition and to avoid ambiguity. That is a common function of technical vocabulary standards: they do not only list preferred names, but also define the boundaries of the subject field.

Why the distinction matters in technical work

From a general technical perspective, bitumen is a viscoelastic petroleum-derived material, while bituminous binders is a broader expression that may cover modified, emulsified, cut-back, or otherwise formulated binder systems based on bitumen. Distinguishing these concepts is important in road engineering, industrial applications, laboratory reporting, and procurement language, because formulation, handling, and intended use can differ significantly. A terminology standard helps keep those distinctions consistent across specifications, product descriptions, and technical communication.

For professionals working with paving and industrial binders, this standard serves as a common language reference. Its value lies in reducing ambiguity when material names, process terms, and product definitions are used across documents and organizations.
