TSE CEN/TR 15349

TSE CEN/TR 15349 is a technical terminology document for extension elements used in furniture hardware and for the components of those elements. Table extension elements are excluded; instead, the document focuses on other types of extension systems used across application areas and on how their parts are named and distinguished. As a terminology reference, its main value is consistency: it helps designers, manufacturers and technical authors use the same terms for the same mechanism.

What extension elements mean in furniture hardware

In furniture design, extension elements are mechanisms that allow a surface, support structure or functional section to extend, enlarge or move into an extended position when needed. In practice, these systems may include guides, connecting parts, moving members and locking features, depending on the furniture application. General technical context matters here because similar functions can be achieved by different constructions, and clear terminology prevents confusion between the function, the assembly and the individual component.

How this technical report helps users

The document’s practical contribution is not a performance requirement or test method, but a structured vocabulary supported by figures that present different types visually. That makes it easier to understand technical language in drawings, catalogues, assembly instructions and procurement documents. For the furniture sector, this kind of terminology standard supports clearer communication and more accurate documentation without prescribing how the products must be built or tested.

• Covers all types of extension elements except table extensions.
• Includes terminology for the components of those extension elements.
• Uses figures to distinguish different types.
• Supports consistent technical communication in furniture hardware.
