TSE CEN ISO/TS 80004-2

TSE CEN ISO/TS 80004-2 is a vocabulary standard for nano-objects in nanotechnologies, with a specific focus on terms and definitions related to particles. In practice, this kind of Technical Specification helps different scientific and engineering communities use the same language when discussing nanoscale materials, where size, shape and structure can strongly influence behaviour in ways that are not seen at larger scales.

Nano-object terminology and the role of distinctions

The subject of this part is particle-related terminology within the wider nanotechnology vocabulary. In general technical usage, a nano-object is an object with one, two or three external dimensions in the nanoscale, or an object with nanoscale internal or surface structure. Distinguishing particles from fibres and plate-like forms matters because geometry affects surface area, orientation, aggregation tendency and the way materials are described or measured. A vocabulary standard like this supports consistency in research, manufacturing, testing and reporting.

What this Technical Specification contributes

Based on the stated scope, this document lists terms and definitions for particles in nanotechnology, providing a shared conceptual framework rather than a performance requirement or test method. That makes it useful when the same material must be described consistently across laboratory records, technical reports and product documentation. Its value lies in terminology alignment: helping users interpret nano-related language with greater precision and reducing ambiguity between related concepts.
