Studying amount, location and state of water in modified wood at moisture levels relevant for fungal degradation
2020 - IRG/WP 20-40889
Water is an essential parameter for fungal degradation of wood, but degradation primarily occurs at high moisture levels at water potential in the range of -4 to -0.1 MPa, which corresponds to 97-99.9% relative humidity. At these moisture levels, water is present in the wood structure both in and outside of cell walls. The majority of previous studies on the interaction between wood and water for ...

Mini-stakes – an alternative test method for EN 252?
2023 - IRG/WP 23-20691
Market approval of wood treatment products requires knowledge and prove of long-term durability. Efficiency of wood treatment with a specific product is evaluated based on variety of tests, including penetration evaluation, leaching studies as well as decay tests. EN 252 standard test is a core method for wood durability evaluation in a ground contact, both for commercial product approval and scie...
