About This Item
TS EN ISO 80000-3 is a part of the Quantities and units series devoted to quantities of space and time, giving names, symbols, definitions and units for them. In practice, it supports a consistent technical language for the fundamental quantities used in geometry, physics, metrology and data exchange, while aligning with established SI-oriented notation.
How space and time quantities are used technically
In general technical use, space and time are the two basic axes of measurement. Spatial quantities include concepts such as length, area, volume, angle and position; temporal quantities include duration, instant, period and frequency. These concepts are defined separately so that the same physical situation can be described unambiguously across disciplines and documents.
What this part organises
- A common set of names, symbols and definitions for quantities of space and time.
- Conversion factors where appropriate.
- Consistent use of standard notation in technical documents, calculations and information exchange.
- Reduced ambiguity when the same quantity is referred to by different terms in different fields.
As part of the ISO 80000 family, this document provides a controlled vocabulary and notation framework rather than a design manual or a procedural test method. Its practical value lies in defining how space and time quantities should be identified, written and understood in technical work.
