Proposals for collaborative work on laboratory soft rot testing
1986 - IRG/WP 2265
Proposals for collaborative experiments based on soil burial are presented. It is intended to study the use of defined horticultural loams with a view to obtaining more reproducability in laboratory soft rot tests....

Termiticidal effectiveness of synthetic pyrethroids, carbaryl and chlordane in wood-block test
1985 - IRG/WP 3356
The results of some wood-block tests with allethrin, permethrin, fenvalerate, carbaryl and chlordane against Coptotermes formosanus are tabled and compared against some organophosphates, chlorpyrifos, fenitrothion, phoxim, tetrachlorvinphos and acephate. The treatment of the wood blocks was exactly as described in Document No: IRG/WP/3330. Among the pyrethroids tested, permethrin was the most effe...

Proposal for further work on environmental questions
1988 - IRG/WP 3494
Although very much is known about the environmental and health and safety aspects on various wood preservatives and treated wood knowledge is still lacking on some important issues. Some examples are: - The fate of wood preservatives in the environment, eg by leaching from treated wood and contaminated soil; - How big is the "problem" of pollution, etc from the wood preserving industry in comparis...

Copper based water-borne preservatives: The biological performance of wood treated with various formulations
1987 - IRG/WP 3451
Wood samples treated with the various components of CCA preservative singly and in combination were tested against a soft rot organism, a copper tolerant brown rot organism and in soil burial both unleached and after leaching. The results suggest that, of the elements tested, fixed copper is essential for preventing soft rot attack and fixed arsenic is essential for preventing attack by a copper t...

Sub-group on Basidiomycete tests: Proposals for Sub-group programme of work
1979 - IRG/WP 2127
During the IRG 10 Meetings in Peebles, Scotland in September 1978, it was resolved to establish within Working Group II a sub-group on testing wood preservatives against basidiomycete fungi. The terms of reference and scope of the sub-group's activities were to be determined by consensus among members who registered an interest. Dr A F Bravery (PRL, UK) was asked to act as co-ordinator. D...

The use of bifluorides-diffusion in remedial treatments
1983 - IRG/WP 3256
A description is given about the experience to date of a 14 years' development to bring bifluorides-diffusion from laboratory evaluation to commercial service application. The described treatment is an adjunct to good design and not a replacement for it. The process is also used with an injection method for the remedial treatment of premature decayed external joinery....

Collaborative tests on the influence of solvent and drying method on the toxic limit of wood preservatives against Basidiomycetes
1974 - IRG/WP 248
Seven institutes from five countries, Austria, England, France, Germany and the Netherlands have collaborated in a study on the influences of solvent and drying method on the toxic limits of wood preservatives against Basidiomycetes tested according to the agar-block method. Two preservatives, a 25% pentachlorophenol-concentrate and tributyltinoxide were applied to pine sapwood and beech and teste...

Evaluation by experimentation on site of a new method for termite control
1996 - IRG/WP 96-10173
A new concept of subterranean termite control consists of the installation of toxic baits in or around the infested construction. Dow Elanco has developed a bait system based on Hexaflumuron. This active ingredient is an insect growth regulator with slow acting effect. A lot of trials were conducted in the USA, but none in France until now. We realised on site experiments, in order to estimate the...

Assessment of contamination of soil and water at a CCA treatment plant: A demonstration project
1996 - IRG/WP 96-50067
Soil, sludge, dust and water samples were collected at a copper/chromium/arsenic wood preservation plant. Contamination of soil, sludge, dust and surface water with copper, chromium and arsenic was detected. Levels of contamination were sufficiently high to require remediation. Contamination originated from preservative solution dripping from recently treated wood. Migration of contaminants was vi...

A deflection test for monitoring decay in miniature beams
1986 - IRG/WP 2269
A laboratory apparatus for assessing decay in small stakes is described. It involves the measurement of deflection in a static bending apparatus using a displacement transducer linked to a microcomputer. Measurements are non-destructive, rapid, accurate and automatic and decay can be assessed repeatedly over long time periods....

Phytotoxic effects of preservative treated props for agricultural use
1989 - IRG/WP 3550
The phytotoxic effect due to the use of wood treated with organic preservatives for agricultural purposes was studied. The assays were carried out on plants tutored with props of Pinus sylvestris treated with three different organic wood preservatives. Pre-assays were carried out to observe the reaction on the plants, spreading directly the preservative on different parts of the plant and to the s...

The Pilodyn instrument as a non-destructive tester of the shock resistance of wood
1978 - IRG/WP 2107
A new non-destructive shock resistance tester, the PILODYN, has been developed. The instrument measures the fracture surface area created by a constant amount of energy. It operates by shooting a blunt pin into wood by an exact amount of energy. The penetration depth is read on a scale. A wide field of application is open to a non-destructive shock resistance tester such as: 1) assessment of the r...

Environmental risk assessment of preservative treated wood
1998 - IRG/WP 98-50101-19
This paper reviews the status of the environmental risk assessment of preservative treated wood and confirms the distinction between the risks presented by wood preservatives and preservative treated wood. The paper proposes a tiered approach to risk assessment and discusses the rationale. Flowcharts are presented which summarise the tiered approach to risk assessment, show the tests required, and...

A laboratory evaluation of the susceptibility to biological attack of glued laminated pine timber
1991 - IRG/WP 2387
In the scope of a research programme concerning the use of maritime pine (Pinus pinaster) to produce glued laminated timber structures in Portugal, the natural durability of this material was checked by using laboratory test methods. An European standard, EN 113, was used to test durability against basidiomycetes and a test method developed at LNEC for termites was adapted for this purpose. From t...
