TS ISO 24294

TS ISO 24294 is a vocabulary standard for round timber and sawn timber. In wood technology, the same product may be described differently depending on its form, processing stage, or commercial use; this standard provides a common technical language. Clear distinctions between round timber, logs, sawn timber, and the stages between them are important for trade, measurement, grading, and technical communication.

How the terminology scope is organised

The document covers terms related to identifying a tree and its components, processing stages in round and sawn forms, timber grading, dimensions, anatomical structure, characteristics, moisture content, and conditions relating to stain, fungal attack, and insect attack. Its role is to align how these concepts are named and understood across the wood sector, so that condition, defect, property, and measurement are not used interchangeably by mistake.

Areas explicitly outside the vocabulary

• Terms related to the strength properties of wood are not included.
• Terms for engineered timber products are outside the scope.
• Terms related to timber structures are excluded from this standard.

In general technical context, vocabulary standards do not prescribe test methods; they define the boundaries of terminology. TS ISO 24294 helps establish consistent usage for core concepts such as species, form, dimensions, anatomy, and deterioration conditions across documents and practical work involving timber.
