Standardization concerning structural applications of timber, wood -based panels, other wood based products, and related lignocellulosic fibrous materials including:

  • requirements for design;
  • structural properties, performance, and design values of materials, products, components, and assemblies and;
  • test methods and requirements to establish related structural, mechanical and physical properties and performance.

Note :

In cases where topics of TC 165 are also a subject, for non structural purposes, of the Technical Committee of the relevant material or product (e.g. TC 89 or TC 218) a strong liaison with the relevant Technical Committee will be established.
