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...

Optimisation of accelerated weathering procedure as an alternative to natural weathering
2023 - IRG/WP 23-20693
Comprehensive tests need to be performed to obtain the most accurate data possible on the durability of wood. The most reliable performance tests are field tests. However, since this is very time-consuming, we frequently rely on laboratory tests. To increase the reliability of the laboratory tests, samples are preconditioned with natural or artificially accelerated weathering methods that simulate...

Suitability of boron preservative treatment of minor species as framing in New Zealand buildings
2023 - IRG/WP 23-30778
The inclusion of alternative species to radiata pine, predominantly exotic species, in the building code (NZS 3602) raises questions as to whether they require preservative treatment and, if so, whether they can be adequately treated using current industry processes.
Early research with boron indicated that the dip/diffusion method for green timber would give adequate preservative retention in sa...

Reuse of discarded wood and alternative wood species to replace spruce in the development of wooden windows for complete disassembly – REWINNUSE
2023 - IRG/WP 23-30785
The REWINNUSE project focuses on the reuse of discarded wood and alternative wood species and on the development of wooden windows that can be easily disassembled into their basic components. In cooperation with the project partners (M Sora, the University of Ljubljana Biotechnical Faculty (BF), the Norwegian Institute of Bioeconomy - NIBIO and the Slovenian Forestry Institute (GIS)), the project ...

Tall oil in combination with eugenol for wood protection
2023 - IRG/WP 23-30787
The aim of this study was to investigate the possibility to use tall oil in combination with eugenol for wood protection. The idea was that the eugenol would increase the decay resistance of the tall oil while the tall oil would decrease the leaching of the eugenol.
The results show that an impregnation liquid of 31,5% tall oil, 3% eugenol and 65,5% methanol increased decay resistance of pine sa...

Ultrasound as an alternative treatment in wood protection
2023 - IRG/WP 23-40973
Bursaphelenchus xylophilus Nickle 1970 is probably the most important nematode of the pine, affecting coniferous forest masses, and that has forced the European Union to take measures to prevent its propagation. In sawmills, wood is currently subjected to heat treatment in accordance with the International Standard for Phytosanitary Measures No. 15 (ISPM 15 2019). This standard contemplates three ...
