Developing the technical guidance document on data requirements for biocidal products
1998 - IRG/WP 98-50101-02
Finland has been developing a discussion document for EC and the Member States concerning the specified data requirements for 23 biocidal product types, including wood preservatives, and their active substances. This data is required when applying for authorisation for a wood preservative according to the forthcoming Biocides Directive. The data requirements comprise of the core data set, which is...

Survey of conditioning treatment practices in India
1978 - IRG/WP 3127
India has 75.3 million hectares (ie about 24% of total land area) under forests out of which the area of productive forests, from which industrial wood is available, is about 60 million ha. The Task Force on Forest Resources Survey has tentatively estimated that the total growing stock in Indian Forests is 24,000 million cubic metres (m³). The total recorded production of wood in the country is r...

An investigation of the effects of pre-steaming on the treatment of sawn spruce timber with Celcure A, a copper-chrome-arsenic preservative
1981 - IRG/WP 3150
Difficulties in the treatment of spruce using standard vacuum/pressure techniques with both water-borne and organic solvent preservatives are well known. We have evaluated the influence of steaming on treatability with a waterborne CCA preservative....

Laboratory evaluation of chemicals as termiticides
1986 - IRG/WP 1293
Laboratory procedures are described for screening chemicals against subterranean termites. Fast-acting compounds with persistent termiticidal activity are identified in tests using a soil substrate, and slower-acting bait toxicants are evaluated in a series of tests using cellulose substrates....

Untersuchungen über die Imprägnierbarkeit verschiedener türkischer Holzarten mit wirtschaftlicher Bedeutung
1976 - IRG/WP 370
Holzarten mit einer geringen natürlichen Dauerhaftigkeit können nur dann wirtschaftlich verwendet werden, wenn ihre Gebrauchsdauer durch einen zusätzlichen chemischen Schutz verlängert wird. Holzschutzmaßnahmen können nur regelmäßig geplant werden, wenn die Tränkbarkeit der verwendeten Holzarten bekannt ist. Aufgabe dieser Versuche war es daher, festzustellen, wieweit die Holzarten hinrei...

The effect of treatment method on CCA efficacy in Corsican pine
1992 - IRG/WP 92-3723
As part of a study into the influence of application method on preservative efficacy Corsican pine (Pinus nigra) samples (50 x 50 x 400 mm³) were treated with a CCA formulation using Bethel, Steam/Bethel or Lowry processes. Full penetration of the preservative at a gross level was confirmed using a copper disclosing reagent. The preservative was allowed to fix and then samples were converted into...

Studies of the distribution and degradation of tributyltin naphthenate in double-vacuum treated wood
1983 - IRG/WP 3230
The effects of forced solvent evaporation by kilning redwood (Pinus sylvestris) that has been double-vacuum treated with tributyltin naphthenate (TBTN) have been investigated. Contrary to previous studies reported, it has been shown that forced evaporation can have a considerable influence on the losses of the fungicide. It has been found that, whether the solvent is allowed to evaporate slowly or...

Controlling Coptotermes (Isoptera: Rhinotermitidae) infestations in buildings with bait boxes
2000 - IRG/WP 00-10372
This paper describes the results of a commercial pest control operators use of the CSIRO bait box procedure in controlling infestations within buildings of subterranean termites ('termites') of the genus Coptotermes. Polystyrene bait boxes (480 x 330 x 210 mm3) were filled with alternate layers of corrugated cardboard and kiln-dried hardwood strips of Eucalyptus regnans F. Meull....

Commercially available anti-sapstain chemicals in New Zealand - An update
1987 - IRG/WP 3416
Six anti-sapstain chemicals or mixtures (NaPCP plus borax, Haipen 5F, Mitrol PQ375, Busan 1009, Protek S, Pinefol 50W) are available as commercial treatments in New Zealand. A further two (Hylite 20F and Isothon-35) have shown potential in field and mill trials and will be available for use. A number of other formulations are under evaluation....

On site test for indicative determination of leaching of components of preservatives from treated timber. Part 2: New data on CCA-C, CC and CCB treated timber
1994 - IRG/WP 94-50025
The 'on site test' was published at the IRG meeting in Cannes in February 1993 (IRG/WP 93-50001/12). Since this publication many on site tests were performed parallel to so-called shower tests. The correlation between the test results of the on site tests and the shower test has been established more clearly. For chromium the correlation between both tests is indistinctive of pre...

Rates of emission from CCA-treated wood in the marine environment: measurement, modelling and requirements for further research
2001 - IRG/WP 01-50166-12
Accurate estimates of rates of emission of leachate from preservative treated wood are crucial for realistic predictions of the environmental impact of its use in maritime construction. Estimates are available for some commonly used preservatives, but these vary widely. Though variable, these measurements suggest that emission generally decreases exponentially with time. Part of the variation is d...

Update on lab and field test results for polymeric alkylphenol polysulfide treated wood
2002 - IRG/WP 02-40240
The possibility of using Polymeric Alkylphenol Polysulfide (PXTS) as a wood preservative has been undergoing evaluation in our laboratories for the past four years. Various formulations prepared from this compound have been tested and found to be effective against wood decay fungi and insects in field stakes after 42 months exposure. In accelerated soil bed tests, PXTS has been shown to be consi...

Corrosion of fasteners in heat-treated wood – progress report after two years’ exposure outdoors
2005 - IRG/WP 05-40296
The corrosion of common fastener materials now in use - mild steel, zinc-coated steel, aluminium and Sanbond Z-coated steel – has been evaluated after two years’ exposure outdoors in untreated and heat-treated spruce (Picea abies) respectively.
Spruce from South-western Sweden was used. The heat-treatment was carried out in Finland according to the ThermoWood process at a maximum temperature ...

Light organic solvent preservative treatment schedules for New Zealand-grown radiata pine
1986 - IRG/WP 3379
The influence of pressure differential and treatment time on preservative uptake and distribution in radiata pine heartwood and sapwood is investigated. Treatment schedules are defined which minimise solvent usage but ensure complete sapwood penetration and optimise heartwood penetration....
