TS 697

TS 697 is a terminology and measurement standard for sawn timber made from broadleaved species. It covers broadleaved hardwood timber that may be cut on the sides or left with the sides untrimmed, and that may be planed or left unplaned; it excludes broadleaved timber that has been formed for specific end-use applications.

How the product boundaries are defined

In timber trade and manufacturing, the key distinctions are the tree group, the sawing condition, and the surface finish. Broadleaved hardwood timber is the general category for sawn wood from species such as oak, beech, or hornbeam. Side trimming changes the cross-section by removing outer edges, while planing reduces surface irregularities and can improve dimensional consistency. These distinctions matter because they affect how the timber is described, measured, and compared in practice.

Why measurement terminology matters

A standard of this type provides a common language for dimensions and product description. In general technical use, consistent definitions for length, width, thickness, and sectional form support purchasing, inventory control, quality comparison, and communication between producers and users. The terminology also helps separate raw sawn material from timber that has been additionally processed into a specific shape for use.
