TS ISO 1791

TS ISO 1791 is a vocabulary standard that defines the terms used in building design and construction under the principles of modular coordination. Standards of this kind help keep technical language consistent across drawings, specifications, product literature, and project communication, so that key ideas such as modules, grids, and coordination systems are used with the same meaning.

The technical purpose of modular coordination

In general technical practice, modular coordination is the method of arranging building dimensions and component interfaces around a defined dimensional order. Its purpose is to make planning more systematic, improve dimensional compatibility between parts, and support smoother coordination from design through fabrication and assembly. TS ISO 1791 supports that process by standardizing the language used to describe the subject, reducing ambiguity in technical discussion.

What this vocabulary standard covers

The standard covers the terms necessary for the design and construction of buildings. In other words, it provides the terminology framework for describing architectural and construction concepts in line with modular coordination principles and rules. As a vocabulary document, its role is not to prescribe building methods, but to organize the names and meanings of the concepts used in this field.

• Terminology for building construction
• Core concepts linked to modular coordination
• Standardized terms used in design and construction
• Language support for clearer technical communication

This listing represents a TS ISO edition based on ISO 1791:1983 and marked as withdrawn. It is therefore most useful as a conceptual reference for the terminology of building technology rather than as a current application standard.
