This document gives guidance on the selection of wood species based on their biological durability and selection of wood materials based on their specific enhanced resistance (wood preservative treatment, wood modification and other non-biocidal methods) to attack by wood-destroying organisms for use as solid wood, as engineered wood products (e.g. glulam) and as wood based composites (e.g. plywood, wood polymer composites) in the use classes defined in EN 335.

This standard does not consider:

i) the durability characteristics of the glue used in engineered wood products or wood-based composites;

ii) the aesthetic function of wood products (discoloration, surface weathering, mould);

iii) the strategy for protection of products as it will be different based on priorities of the user and client and the type of product e.g. glulam compared to plywood.
