Establishing the minimum effective penetration of wood preservatives in the refractory heartwood of E. nitens
2023 - IRG/WP 23-30780
Conventional pressure treatment of many Australian hardwoods results in little to no penetration of heartwood and a non-uniform envelope treatment of <5 mm surrounding a mostly untreated core. This is a major issue for many of the low durability plantation hardwood timbers that are grown in Tasmania, which contain high percentages of heartwood. Long term studies on softwoods such as spruce decking...

Field test methods as long-term aging – report of selective wood properties
2023 - IRG/WP 23-40962
Wood samples from a long-term field test are a valuable compendium of information about the material in the context of its aging processes. In the current work, wood samples from the round-robin test within the ECOMOD project were used as a material for the natural aging process (III and IV class of utility). The research scope was to determine selected properties of this wood which can be partial...

Leaching and chemical redistribution of CCA components in refractory heartwood of E. nitens
2024 - IRG/WP 24-41011
Chromated Copper Arsenate (CCA) is a wood preservative widely used to protect against fungal and insect attack. The fixation mechanism of CCA involves complex chemical reactions, including the reduction of chromium (VI) to chromium (III) and the formation of insoluble complexes. Despite fixation efforts, a portion of CCA components tends to leach from treated wood, influenced by factors like wood ...

AI Models for Accelerating Wood Protection Testing: Development of Predictive Tools Based on Long-Term Field Test Data
2025 - IRG/WP 25-41023
In this study, we present the development of DecAI, an artificial intelligence (AI) model designed to optimise and accelerate performance evaluations of wood protection products in the European EN 330:2014 "Field test: L-joint method." The Danish Technological Institute (DTI) compiled a dataset of over 100,000 data points from approx.10,000 L-joint samples collected over +15 years at field sites i...

Quantitative Prediction of Latent Deterioration in Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41038
Wood coatings play a vital role in prolonging the lifespan of timber structures by protecting them from environmental degradation. However, conventional evaluation methods rely on visual inspections, which cannot detect latent deterioration before visible damage occurs. This study integrates attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy with partial least squares ...

Development of an Early Degradation Diagnosis Technology for Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41047
Accurately predicting the degradation state of wood coatings is challenging, and as the coating deteriorates, it becomes a major factor accelerating the degradation of the wood itself. In this study, we aimed to develop a diagnostic technology that combines mid-infrared spectroscopy and machine learning to assess latent coating degradation, which cannot be detected visually, and to enable appropri...
