Laboratory durability testing of preservative treated wood products – first attempts and observations
2023 - IRG/WP 23-20697
In the past, durability classes (DC) had been assigned to wood species, sometimes also to homogenously modified wood-based materials such as thermally modified wood. More recently, some standards allow for classifying the biological durability of chemically modified wood, preservative treated wood and wood composites. Even treated products may be subject to durability classification, but necessary...

Adhesion and performance of exterior wood coatings on chemically and thermally modified wood – Results from 5.5 years outdoor exposure
2023 - IRG/WP 23-40964
Non-durable softwood and hardwood species were treated with the water-soluble cyclic N-methylol compounds 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) and methylated DMDHEU. One half of the modified specimens were coated with a waterborne acrylic coating system prior a natural weathering for 5.5 years according to EN 927-3 (2020). By frequent evaluations, the impact of chemical modifications ...

Durability and service life of wood in constructions. The Spanish approach of European Standard EN 460
2025 - IRG/WP 25-41028
The durability of wood is an important factor to be considered in the construction influencing in final durability and expected service life of a wood product in construction. There are many factors influencing in the durability (service life) of a wood in construction: Natural durability of wood species, preservative treatments and protection by design; combined with the variability of environmen...
