TS 2255

TS 2255 is a terminology standard for doors used in buildings, focused on hinged and pivoted doors. It establishes a common technical vocabulary for the structure, parts and usage context of doors so that design, manufacture, installation and technical communication can use the same terms consistently. This document is not a performance specification; it is a naming and conceptual reference for door-related terminology.

Why door terminology matters

In door technology, terms are not just labels. Elements such as the leaf, frame, hinges, pivot arrangement, locking hardware and opening direction determine how a door is understood and described. In hinged doors, the leaf typically rotates about an edge-mounted hinge line, while pivoted doors rotate about a differently positioned axis. These distinctions help reduce ambiguity in architectural drawings, product descriptions and technical communication. In general technical practice, terminology standards aim to define the language of the subject rather than specify dimensions or strength values.

What this document covers

• Doors used in buildings.
• Hinged and pivoted door types.
• Doors made from any material.
• Terminology and naming conventions for door components.
• It is identified as equivalent to ISO 1804:1972.

For designers, manufacturers, installers and technical authors, TS 2255 serves as a shared reference point in door systems work. Because naming can vary across materials and construction methods, standardised terminology helps keep project language and technical records consistent.
