TS EN 844-12

TS EN 844-12 is one of the concluding parts of the round and sawn timber terminology series, bringing together additional terms and the general index for this subject area. It serves as a reference framework for reading and using timber terminology consistently in standards and technical documents.

Where this part sits in the terminology structure

In timber technology, round timber refers to wood in its more or less original cylindrical form, while sawn timber is wood that has been processed by sawing into defined dimensions. Terminology standards help ensure that terms for size, quality, defects, grades and geometry are used with a common meaning. This part focuses on additional terms rather than repeating the core vocabulary, and it provides a general index to make the series easier to navigate.

General technical context

Clear terminology matters in timber trade, grading, quality control and technical documentation. The distinction between round timber and sawn timber reflects the stage of processing and the intended use of the material. The vocabulary covered by this standard supports consistent interpretation across related standards; it is not a product test method or a performance standard in itself.

• Round timber: wood products in log or near-log form before sawing
• Sawn timber: timber processed by sawing into specified dimensions
• Additional terms: supporting terminology that complements earlier parts of the series
• General index: an organised index for quicker access to related terms
