About This Item
TS ISO 18115-1 is a vocabulary standard for surface chemical analysis. This part brings together general terms and the terminology used in spectroscopy, giving users a common technical language for describing surface-related measurements, signal origins, data types, and the concepts that underpin interpretation of results.
Why terminology matters in surface analysis
Surface chemical analysis deals with the outermost region of a material, where composition and chemical state can differ markedly from the bulk. In spectroscopic methods, the measurement is based on detected signals generated by photons, electrons, or other excitations, so precise naming of concepts such as sample region, measured signal, and analytical outcome is essential for clear communication.
In broader technical practice, surface analysis is not the same as bulk analysis. Very thin contamination layers, oxidation, adsorption, or coatings can strongly influence what is observed at the surface. A controlled vocabulary helps researchers, instrument users, and authors apply the same terms consistently across reports, databases, and publications.
Document boundaries and related coverage
- This part covers general terms for surface chemical analysis and terms used in spectroscopy.
- ISO 18115-2 covers terms used in scanning-probe microscopy, separating that field from spectroscopy-related vocabulary.
- The document is a vocabulary standard rather than a method standard; it does not define test procedures or numerical performance limits.
- TS ISO 18115-1 is listed as withdrawn, but it remains a useful reference for the terminology of surface chemical analysis.
