Towards a colour assay of wood degradation
1982 - IRG/WP 2180
A colour assay for the enzyme catalase is described. Since the activity of this enzyme has previously been shown to be correlated with degree of wood degradation as determined by other methods, this assay may provide a rapid quantitative indicator of superficial and internal wood decay....

The effect of low molecular weight chelators on iron chelation and free radical generation as studied by ESR measurement
2000 - IRG/WP 00-10367
The focus of this work was to improve our current knowledge of the non-enzymatic mechanisms involved in brown-rot decay. Electron Spin Resonance (ESR), also known as Electron Paramagnetic Resonance (EPR), is an attractive technique for the identification and study of chemical species containing unpaired electrons (such as radicals and certain transition metal species). ESR spin-trapping techniques...

Visualization of inorganic element distribution in preservative treated wood by SEM-EDXA
2001 - IRG/WP 01-40208
SEM-EDXA was found to be an effective way of visualizing inorganic element distribution in wood as it was possible to examine some inorganic elements at the same time and map the concentration differences in color. Japanese cedar sapwoods were impregnated by vacuum treatment with CuAz or by pressure treatment with CCA preservatives and then distribution of Cu, Cr and As elements in wood were exami...

Influence of variable lignin content on brown rot decay of wood
1987 - IRG/WP 1320
Compilation of published data and new experiments with brown-rotting fungi on different timber species suggest that their decay activity, in contrast to soft rot and white rot fungi, is not greatly influenced by the type or amount of lignin present....

Tebuconazole - a new triazole fungicide for wood preservation
1991 - IRG/WP 3680
The great potential of Tebuconazole for wood preservation is demonstrated. Test carried out by official institutes shown that Tebuconazole is particularly effective against wood-rotting basidiomycetes strains. The efficacy of Tebuconazole against the brown rot Gloeophyllum trabeum is outstanding: the toxic value measured in accordane with EN 113, without·ageing, after leaching (EN 84) and after e...

Water-borne wood preservatives against marine borers. Results from NWPC marine trials started in 1972 and 1976
1990 - IRG/WP 4162
The paper presents the results from NWPC (Nordic Wood Preservation Council) marine trials started in 1972 and 1976. The trials are carried out according to the NWPC Standard No. 1.4.2.2./73 "Marine test - a test against marine wood boring organisms in sea water". The test site is Kristineberg Marine Biology Station on the west coast of Sweden. The wood blocks used in the trials were made from sapw...

The status of marine wood preservation in Papua New Guinea
1974 - IRG/WP 405
The life-expectancy of Papua New Guinea hardwoods in the marine environment has in the past been too short to be an economical proposition, a service life of six to twelve months being obtained from some of the timbers susceptible to marine wood borer attack. Consequently plans for wharves and other marine structures have specified the use of imported materials such,as steel and concrete. Due to t...

Effect of EDTA on removal of CCA from treated wood
2002 - IRG/WP 02-50182
Since substantial amounts of chromated copper arsenate (CCA) remain in the wood for many years, the disposal of CCA-treated wood causes escalating environmental concerns. Additionally, wood waste is generated when treated wood is put into service, for which environmentally benign disposal technologies need to be developed. Novel approaches to remove copper, chromium, and arsenic from CCA-treated w...

Determination of physical properties of wood by Novel Guide
2006 - IRG/WP 06-40345
In empirical and theoretical determination of physical properties of wood, a schematic guide has been developed (as a novel guide) for the purpose of bringing facilities to researchers with a processing quantity in terms of data compilation. In this article physical properties of wood have been briefly described in respect to their effect on impregnation process, and technical information has been...

Role of Global Cooperation in Wood Protection for Conserving Forest Resources
2007 - IRG/WP 07-50249
The current uses of treated wood are discussed along with the emerging concerns for continued use of these products. The issues of new chemicals, treatments for wood based composites, migration of chemicals from treated wood, and the disposal of these products at the end of their useful life are all outlined. The potential for the IRG to serve as the focus for research discussion as well as coll...

Wood preservation in Turkey
1982 - IRG/WP 3216
The report reviews the forestry potential of Turkey and also the historical background of wood preservation in the country. The wood preservation industry in Turkey is mainly concentrated on the treatment of poles and railway sleepers. There is no official body responsible for wood preservation activities, and therefore its promotion depends mainly on the voluntary research efforts carried out by ...

Investigation of some technical properties of heat-treated wood
2003 - IRG/WP 03-40266
The objective of this study was to investigate some technical properties of heat-treated wood.
Wood heat-treated according to a process intended for wood in above-ground end-uses (European hazard class 3) was subject to the following:
· A delamination test according to EN 391 with glulam beams made of heat-treated pine (Pinus sylvestris) and spruce (Picea abies) laminations, assembled with PR...

Exterior wood stains
1980 - IRG/WP 3135
Experience has shown that conventional paints cannot now be relied upon to provide a complete seal against water entry, that in practice water can often circumvent the film and that the paint, far from serving to keep water out will seal it in. Moreover present-day paints are often subject to localised and premature failure out of doors and consequently entail high maintenance costs. Problems of w...
