New developments in wood preservation
1974 - IRG/WP 335
Most of the developments in wood preservation in recent years have been stimulated by changing circumstances, particularly the increasing interest in reducing hazards and environmental, pollution but also the serious difficulties that are now being encountered in obtaining economic supplies of established preservatives. There is perhaps a danger that new controls to reduce pollution dangers may be...

Evaluation and approval of wood preservatives in Japan
1988 - IRG/WP 2303
Japanese standardized decay test methods, performance requirements and approving system are briefly described. JIS (Japanese Industrial Standard) A 9302, which is related to a testing method for evaluating effectiveness of wood preservatives when applied to pressure treatment, is fundamentally a sand-block laboratory test method. According to performance requirements in JIS A 9201, mean percentage...

Effect of felling time related to lunar calendar on the durability of wood and bamboo
-Fungal degradation during above ground exposure test for 2 years- (Preliminary report)
2005 - IRG/WP 05-20311
Current study was carried out to know whether the felling time of trees and bamboos based on lunar calendar affects natural durability of felled wood-bamboo or not. Each of one sugi (Cryptomeria japonica) tree of 28 years old and one Moso bamboo (Phyllostachys heterocycla) of around 3 years old was cut 12 times between February and December in 2003. Six sets of sugi tree and bamboo were felled in ...

EPR investigations of interactions between ammoniacal Cu(II) octanoate and wood
1996 - IRG/WP 96-30110
Ammoniacal solutions of copper(II) octanoate [ C u . h l f . 2 . r h l f.(O2CC7H15)4], interactions of these solutions with wood and wood components, and leaching of copper(II) octanoate from impregnated wood samples, have been studied by electron paramagnetic resonance (EPR) method. It is still not clear if in the Cu(II) octanoate - water - ammonia system, Cu(II) remains in a (copper(II) octanoat...

Biological agents of timber degradation in Portugal. Marine borers
1991 - IRG/WP 4171
A brief report of the studies carried out in Portugal on marine borers is presented. The marine borers found in the portuguese coast are refered as well as the wood species where those organisms were identified. Emphasis is given to a study carried out from 1960 to 1975 at the Tagus estuary in Lisbon with the purpose, among others, of establishing the natural durability of different timbers....

Study of the natural durability and impregnability of a metropolitan species of tree
1986 - IRG/WP 2261
The current and predictable evolution of construction timber supply conditions is motivating research for a more efficient utilization of native woods. It is now important to determine statistically reliable impregnability values on a national scale, and to evaluate the natural durability of woods recently introduced in France, or economically important native woods....

A preliminary report on lignicolous marine fungi in the Java Sea, Indonesia
1982 - IRG/WP 488
This report is part of a study on the natural durability of Indonesian timbers against marine borers conducted in Pari Island waters, Java Sea (Suhirman and Eaton, 1981), and contains preliminary information which has not yet been published....

Treatment of precut timbers
1991 - IRG/WP 3665
A serious lack of house construction technicians has produced a trend in which wooden parts of a house are processed by computer aided precut machine and the precut wood is treated with termiticides and/or fungicides at the plant site. We have developed a new system to handle these requirements of homebuilding. This system is a combination of incising machine, spray machine and proprietary oil-bor...

Statistically stable models for determination of PEC
1999 - IRG/WP 99-50135
In June 1998 the European Wood Preservative Manufacturer's Group prepared a document to support the Technical Guidance concerning the placing of products on the market with respect to the Directive 98/08/EC (BPD). The essentials of this document were presented at the COST E2 meeting in Cannes last year and at the following IRG conference (Baines and Davis, 1998; IRG/WP/98-50101/20). The d...

Biodeterioration and preservation of rubberwood (Hevea brasiliensis)
1994 - IRG/WP 94-10084
Plantation-grown rubber trees (Hevea brasiliensis) in the tropics is fast emerging as a significant provider of quality hardwood for a variety of non-structural products, as the aesthetics of the timber is its creamed colour resembling perhaps the priced but depleting Ramin wood or even American beechwood. However rubberwood logs and sawn materials are highly sensitive to sapstain, fungal decay an...

Laboratory fumigations to determine the minimum temperature for methyl bromide eradication of the oak wilt fungus in red oak
1983 - IRG/WP 3243
Laboratory chamber fumigations of naturally-infected ret oak log sections exterminatet the oak wilt fungus in sapwood at temperatures down to 0°C. Only low, sporadic fungus survival was observed when log sections were gassed with methyl bromide at -5°C and aired for 4 da. at 0°C. Lower temperature treatments were not effective even if gas levels or exposure times were increased by 50%....

Justification for use of mirex in termite control
1988 - IRG/WP 1346
In August 1987, organochlorines were withdrawn in North America from use in termite control. This has left the industry and the community with reduced options in long term protection of wood and wood products. A case is presented to justify the use of the slow-acting stomach termiticide, mirex, under special permit, for use only in the bait-block method of termite control. This method, while not a...

Current models used by the European Health Authorities to evaluate the volatilization of active ingredients from treated wood used inside dwellings. A case study: Volatilization of azaconazole and propiconazole from treated wood
1990 - IRG/WP 3565
The use of wood preservatives inside houses may result in measurable aerial concentrations of active ingredients. These airborne contaminants may be inhaled by the inhabitants over periods lasting from a couple of days to several months. To assess the potential health hazard of preservative residues in the air, various risk-assessment models have been worked out. Three schemes, currently used by t...
