TS EN 12440

TS EN 12440 addresses the criteria used for naming natural stones. In practice, this subject matters whenever stone products such as marble, granite, limestone, travertine, and similar materials need to be identified consistently for technical and commercial use. The title points to a structured naming approach based on distinguishing characteristics rather than on a single trade name alone.

How natural stone names are distinguished

In general technical terms, natural stone denomination draws on features such as petrographic structure, dominant mineral content, colour, texture, veining, grain size, and geological origin. Those distinctions matter because two stones that look alike may differ in density, workability, surface response, wear behaviour, or visual performance in a project. Clear naming helps reduce ambiguity when specifying, comparing, and sourcing stone materials.

Why denomination criteria matter in trade and specification

For natural stone products, naming is not just a cataloguing exercise; it is part of product identification across supply chains, documentation, and site communication. Because common names and scientific descriptions do not always align perfectly, denomination criteria help keep the material group understandable and consistent. This record identifies a withdrawn edition of the standard, so the description should be read as general technical background on the subject rather than as a claim about detailed requirements, limits, or methods in the full text.
