Assessment of Scots pine sapwood susceptibility to moulds by determination of fungi growth and ergosterol content in infested wood
2014 - IRG/WP 14-20540
…fungi growth is necessary for easier and more comparable assessment of the susceptibility of wood and wood based-materials to the fungi. In these studies, we tried to evaluate susceptibility of wood to the filamentous fungi not only by standard visual grading of mould fungi growth on wood surface, but also by…

In-ground durability of wood-based products – Comparative assessment of graveyard field tests and terrestrial microcosms
2014 - IRG/WP 14-20538
Traditionally wood durability and the effectiveness of wood preservatives are determined in so-called graveyard tests (according to EN 252 or AWPA E7). For laboratory testing, terrestrial microcosms (TMC) can serve as an alternative. Both tests have been appli…

Assessment of the marine borer resistance and abrasion resistance of lesser known hardwood timber species for use in marine construction
2010 - IRG/WP 10-10711
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a pe…
