Field trials of anti-sapstain products. Part 1
1991 - IRG/WP 3675
The results obtained in two field tests of anti-sapatain products, carried out in four locations in Portugal, are presented. Boards from freshly cut logs were hand-dipped, close staked and left to dry for periods from four to six months. The results obtained seem to indicate that some of the products tested performed at least as well and sometimes better, than a 3% NaPCP solution which was used as...

Performance of surface-treated hardwoods and softwoods out of ground contact
1990 - IRG/WP 3592
A number of fungicides were tested as brush treatments for protection of southern pine, Douglas-fir, maple, and red oak against decay above ground. Cross-brace and L-joint test units were treated just before assembly and exposed from 3-10 years. Untreated Douglas-fir cross-brace units were not decayed at either the Mississippi or Madison, WI, site. Untreated red oak cross-brace units were not deca...

Collaborative experiments in testing the toxicity of wood preservatives to soft rot fungi
1970 - IRG/WP 25
Eight Institutes from seven countries, Austria, England, France, Germany, Holland, Sweden and Switzerland have collaborated in an attempt to assess the suitability of various laboratory test procedures for acceptance as standard methods of determining the toxicity of wood preservatives to the cellulose-attacking micro-fungi which cause 'soft rot' of wood. Pure culture methods wit...

Relationship between stacking, location and antisapstain preservatives on visible degrade of Eucalyptus regnans and Pinus radiata boards
1999 - IRG/WP 99-20162
An antisapstain trial was established at a Eucalyptus hardwood sawmill in Victoria, Australia. The trial incorporated two commercial formulations of antisapstain preservatives, used at four different concentrations on both hardwood (Eucalyptus regnans F. Muell) and softwood (Pinus radiata D. Don) boards. The trial also utilised different stacking methods (block-stacked, sticker-stacked, and block-...

Preservative-treated wood as a component in the recovered wood stream in Europe – A quantitative and qualitative review
2004 - IRG/WP 04-50218
Wood preservatives have been used for the protection of timber products in the European market in appreciable quantities for about 100 years. Between the 1960s up to the present day this usage has been particularly noticeable. The aim of this paper is to present quantitative and qualitative data on the volumes of preservative treated wood placed on the market in the UK and Sweden and to evaluate t...

Current and future options for managing used preservative-treated wood
1995 - IRG/WP 95-50042
The amount of preservative-treated wood available for disposal will continue to increase exponentially in the next several decades as landfill availability declines. At the same time, recent legal ruling on competitiveness among utilities and disposal of ash has clouded the economic outlook for combustion of treated wood for energy recovery. This report identifies current and future options for ma...

nvestigation of anomalous fixation and leaching of CCA-treated red maple
2004 - IRG/WP 04-30341
The fixation of CCA-C preservative was investigated in red maple sawdust (Acer rubrum L.) at target retentions of 4.0, 6.4, 9.6 and 30.0 kg/m3. The effect of water-soluble extractives on the course of fixation was evaluated comparing the non-extracted with pre-extracted samples treated to 6.4 and 30 kg/m3. Leaching of the CCA components was monitored after complete fixation for all retentions. Fix...

Co-operative research project on L-joint testing. Progress report to March 1988
1988 - IRG/WP 2315
Further sets of data received from CTFT (France), BAM (Germany) and PRL (UK) after 46-48 months exposure and STU (Sweden) after 22 months exposure are presented and discussed in conjunction with data reported previously. Colonisation and attack of the L-joints has progressed with increasing exposure period. The new data are generally in agreement with those presented previously and the major diffe...

Conservation of wooden cultural property
1994 - IRG/WP 94-30038
A survey of the conservation of wooden archtitectual monuments, art objects and archaeological finds is presented. Each of the three areas has typical conservation problems which reqire the use of selected wood preservatives and consolidation agents. Furthermore specific protection and consolidation methods are necessary. A precise damage diagnosis with non-destructive testing methods is the first...

Comparative performance of pentachlorophenol and copper naphthenate in a long term field stake test
2000 - IRG/WP 00-30243
In this study the performance of copper naphthenate (Cu-Nap) and pentachlorophenol (Penta) treated pine stakes against decay and termite attack were compared at two test sites in Mississippi. Four different petroleum oils meeting AWPA Standard P9-A were used as carriers for these wood preservatives. After ten years exposure, the efficacy of Cu-Nap at a retention level of 0.05 pcf Cu was equivalent...

Ultrastructural and TEM-EDAX studies on the degradation of CCA treated radiata pine by tunnelling bacteria
1985 - IRG/WP 1260
An ultrastructural study was carried out on bacterial attacked Pinus radiata stakes treated with a high level (24.7 kg/m³) of Tanalith NCA preservative. The purpose of the investigation was to determine whether the organism possessed intracellular and/or extracellular detoxification mechanisms in order to overcome the high levels of copper, chrome and arsenic present within the wood fibre walls. ...
