TS 2352

TS 2352 is a terminology standard that gathers the terms and definitions used in the study, specification, and application of dimensional tolerances for buildings. It clarifies how concepts such as size, position, and accuracy are named in building work, helping designers, specifiers, contractors, and site teams use the same technical language.

Core concepts in building tolerances

In general technical usage, a tolerance is the acceptable variation from a nominal or intended dimension. In the building field, this is usually considered alongside geometric attributes such as flatness, straightness, verticality, horizontality, location, and alignment. A vocabulary standard helps prevent these terms from being used interchangeably when they describe different kinds of dimensional control.

What this document covers

• Terminology used when studying and defining tolerances for buildings
• Basic terms connected with dimensional accuracy in construction and installation
• The conceptual language used to describe the dimensional conformity of building components

This document is not a performance standard that sets tolerance limits or prescribes calculation procedures; its focus is the definition of terms. Its equivalence to ISO 1803:1973 indicates alignment with internationally used vocabulary for this subject area. In practical terms, the standard supports a shared technical language rather than measurement methods themselves.
