TS EN 14076

TS EN 14076 is a terminology standard that defines the common technical language used for timber stairs and for timber in prefabricated stairs. Standards of this kind help ensure that stair components, material names, and structural concepts are understood consistently, reducing ambiguity in design, manufacturing, specification, and communication.

The role of terminology in timber stairs

Stairs are more than a set of steps: they are assemblies in which treads, risers, supporting members, balustrades, and fixings work together. In timber stairs, different material types may also appear within the same system, including solid wood and wood-based materials. The focus of this standard is to define the general terms used in this field and provide terminological consistency. This helps avoid confusion caused by different parties using different names for the same element.

Technical boundaries of the scope

• Covers general terms relating to timber stairs.
• Also applies to timber used in prefabricated stairs.
• Includes terminology relevant to wood-based materials.
• Provides a vocabulary framework; it is not a design, calculation, or test-method standard.

In broader technical practice, terminology standards like this help align naming across countries and across different construction documents. In the building products sector, clear terminology supports correct material selection, product description, and technical documentation. The value of TS EN 14076 lies in giving timber-stair concepts a single, consistent language.
