Standardisation of sapstain tests - A challenge
1992 - IRG/WP 92-2403
In the last decade many new anti-sapstain products have been tested world-wide under laboratory and field conditions. Several extensive test programmes have been executed with different non-standardized test methods and procedures, with the result that the biological findings cannot be compared with each other. In this paper, gathered recommendations will be given in order to standardize test meth...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 5: Interim report
1980 - IRG/WP 454
Wood samples (15 x 2 x 2 cm³) were treated with one copper/chrome/arsenic (CCA) and one copper/chrome/boron (CCB) preservative using the following concentrations - O, 3, 6, 10%. Treated samples of three reference wood species - Alstonia scholaris, Fagus sylvatica, Pinus sylvestris were supplied to all participants. Additional local species were chosen by participants and included in the test at t...

FTIR characterization of copper ethanolamine - wood interaction
1999 - IRG/WP 99-20154
The interaction of copper ethanolamine (Cu-EA) and wood components was studied by using Fourier transform infrared spectroscopy (FTIR). In Cu-EA treated wood, significant reduction was noticed on the band attributed to carbonyl vibration from carboxylic groups at 1735±5 cm-1 and an increase in band intensity was obtained from carbonyl in carboxylate at 1595±5 cm-1. The same observation was made ...

International co-operation in wood preservation research
1979 - IRG/WP 3145
If one searched the literature, one could find many examples of international co-operation in the field of research in wood preservation. For example, individual workers in different countries in Europe have got together and made replicate tests with both fungi and insects on various preservatives of common interest and their results have been published. Much co-operation has not had its results p...

Danish wood preservatives approval system with special focus on assessment of the environmental risks associated with industrial wood preservatives
2001 - IRG/WP 01-50166-01
The following is a description of the procedure used by the Danish Environmental Protection Agency to assess the environmental risks associated with preservatives used in the pressure impregnation of wood. The risk assessment covers issues considered to be of significance for the environment and which are adequately documented so as to allow an assessment. Such issues are persistence and mobility ...

Confocal laser scanning microscopy of a novel decay in preservative treated radiata pine in wet acidic soils
1997 - IRG/WP 97-10215
Light microscopy of radiata pine (Pinus radiata D. Don) field test stakes (20x20x500mm3) exposed in wet acidic (pH 3-4) soil for 12 - 24 months showed predominance of an unusual type of decay characte-rised by tunnelling attack of wood cell walls. After two years decay was moderate to severe in wood treated to ground contact CCA specifications and also equivalent retentions of creosote, and a numb...

Effect of acetylation on decay resistance of wood against brown-rot, white-rot and soft-rot fungi
1989 - IRG/WP 3540
Effect of acetylation on decay resistance of wood was investigated using wood blocks of Cryptomeria japonica, Pinus densiflora, Albizia falcata and Fagus crenata. Blocks were treated with uncatalyzed acetic anhydride for different lengths of time and exposed to Tyromyces palustris, Serpula lacrymans, Coriolus versicolor and unsterilized soil. The action of OH-radical on acetylated wood was also ex...

Wood preservation in Poland
2004 - IRG/WP 04-30362
Dynamic growth of market demand for wooden elements and articles, generated in Poland increase of interest in industrial preservation. Today, Poland is a substantial producer and exporter of wood made products. Majority of exported wood - approximately 70% - is scotch pine (Pinus silvestris L.), which, due to its natural durability, requires preservation....
