A comparison of methods – how to achieve a robust and conclusive durability classification of wood
2025 - IRG/WP 25-11063
The biological durability of wood is a relative and unitless size, and therefore wood species and wood-based materials are assigned to durability classes (DC). In Europe, such classes are based on a variety of measures, which can be absolute or relative to a non-durable reference species. The aim of efforts to develop and standardise methods for determining biological durability should be to ensur...
