TS EN ISO 80000-3

TS EN ISO 80000-3 is the part of the Quantities and units series devoted to space and time. It brings together the terminology and unit usage associated with fundamental geometric and physical measurements, helping technical users express quantities such as length, area, volume, angle, and time in a consistent way.

How space and time quantities are used in technical work

In general technical practice, space and time are two of the most basic dimensions used to describe the physical world. Spatial quantities define position, size, shape relationships, and motion, while temporal quantities describe duration, sequence, and rates of change. Standardised terminology matters because it reduces ambiguity in calculation, drawings, data exchange, and technical documentation.

From the supplied record, this TSE edition is based on EN ISO 80000-3:2013 and is now withdrawn. The document therefore belongs to the vocabulary-and-unit framework for this subject area, rather than to a product-specific or test-method standard. Beyond that verified scope, no clause-level requirements, numerical limits, or prescribed test procedures should be assumed from the listing alone.

• Spatial quantities cover position, distance, dimensions, and directional relationships.
• Temporal quantities cover time, moment, duration, and time intervals.
• Consistent naming supports clearer communication across science and engineering disciplines.
• The series helps align symbols and units in technical writing and calculations.
