TS ISO 6955

TS ISO 6955 is a vocabulary standard for the terms and definitions used in flame emission, atomic absorption and atomic fluorescence spectrophotometry. These techniques belong to atomic spectroscopic analysis, where elements are converted to free atoms and the resulting light interaction is measured; consistent terminology is essential for accurate communication and interpretation.

The standard is intended to facilitate understanding among analysts. It gives priority to terminology used in Turkish, English and French, and it takes IUPAC nomenclature into account. In practical terms, this kind of vocabulary document helps laboratories and technical publications use the same concepts with the same meaning across languages and disciplines.

How the terminology framework is organised

Flame emission, atomic absorption and atomic fluorescence are closely related, but they differ in the way the analytical signal is produced. In emission, excited atoms give off light; in absorption, free atoms absorb incident radiation; in fluorescence, light emitted after excitation is measured. Because those signal pathways are different, the associated terms need precise definitions rather than loose everyday wording.

This document is primarily a terminology reference, not an analytical test method. It does not set instrument settings or numerical performance limits; instead, it defines the language used to describe concepts in atomic spectroscopic analysis. That makes it especially useful where terms such as calibration, signal, interference, sensitivity and selectivity must be understood consistently.

• Specialised terms for flame emission, atomic absorption and atomic fluorescence spectrophotometry
• Harmonised use across Turkish, English and French
• Attention to IUPAC nomenclature
• Definitions designed to support clear communication among analysts
