Principles and procedure of the planeing test
1981 - IRG/WP 2162
Small end-sealed samples of pine-sapwood (1.5 x 2.5 x 5 cm³) are treated by brushing and afterwards different parts of the treated surface are removed. The remaining part of the sample is tested against either insects or fungi. If no attack occurs sufficient amounts of biocides have been penetrated at least beyond the zone which has been removed. In spite of some problems the test seems the only ...

Soil blocks versus field test for evaluating and standardizing wood preservatives: A commercial view
1994 - IRG/WP 94-20024
On the basis of technical considerations, experience, costs and applicability, the author concludes that the soil block test and other laboratory tests have little meaning in a wood preservative standardization process and almost no merit in the commercialization of a wood preservative system. Field tests at sites known to be aggressive to preservative treated wood are strongly recommended....

AAC preservatives: Recent New Zealand and Australian experience
1982 - IRG/WP 3188
This paper outlines the present commercial situation in New Zealand, presents results of current research undertaken at FRI and CSIRO, Division of Building Research (DBR), and comments on parallel research carried out elsewhere. Finally, some general comments are made on the limitations of present technology....

Copper naphthenate performance: A new way to look at old data
2000 - IRG/WP 00-30215
Although copper naphthenate has over a 50-year test history, it is still considered as a "new" preservative in the United States when it is used for utility poles. It has also been extensively used in remedial treatments for poles and has considerable retail or over-the-counter sales. The test history includes a number of different tests and a rationale for evaluating this data and comparing the p...

Spruce lumber treatments with ammoniacal solutions of inorganic preservatives
1977 - IRG/WP 391
As a part of our work in the Wood Preservation group at the Eastern Forest Products Laboratory in Ottawa to facilitate exploitation of spruce, which is a large timber resource in Canada, we have been studying the treatability of spruce roundwood. A report on this subject was presented to this group last year. More recently, another commodity - spruce timber - has been rapidly gaining the interest ...

Use of vermiculite as substrate in assays on phytotoxicity of treated wood
1989 - IRG/WP 3547
It is considered the possibility of using vermiculite instead of soil as substrate in assays on phytotoxicity of wood treated with preservatives for agricultural use. Three organic preservatives were used. It had been tested the behaviour of both, vermiculite and soil in case of preservative leaking due to a leach. So that, assays of germination with cucurbitaceous were carried out, mixing a dose ...

CEN Draft (38 N 460E) Standard: Test method for determining the protective effectiveness of a preservative in the marine environment
1986 - IRG/WP 4132
This European Standard describes a marine test method which provides a basis for asseasing the effectiveness of a wood preservative used to prevent attack of timber in sea-water by marine borers. The method is only suitable for testing preservatives which are intended to prevent attack by marine wood boring organisms of treated timber for use in more or less permanent contact with sea-water. It is...

Effects of various preservative treatments on the mechanical and physical properties of plywood
1993 - IRG/WP 93-40007
The technical properties of plywood are related to both the intrinsic characteristics of its composing wood species and the quality and performance of the glue bond which acts as an interface between veneer sheets. Consequently mechanical and physical testing and glue bond strength analysis offer an appropriate means for studying the effect of preservative treatments on the overall quality of plyw...

Exposure trial at tropical marine sites of pyrethroid/creosote mixtures as wood preservatives: Preliminary results
1989 - IRG/WP 4155
Pinus sylvestris sapwood blocks measuring 25 x 25 x 200 mm³, impregnated using a Lowry or Rüping pressure treatment cycle with solutions of permethrin, cypermethrin or deltamethrin in BS144 creosote, have been exposed at marine sites in Australia, Papua New Guinea, the U.K. and Singapore. The effectiveness of these solutions in preventing marine borer attack is being compared with the efficacy o...

A new wood preservative based on polymerized complexes of aminotriazole with copper acetate
1998 - IRG/WP 98-30169
This paper presents the results of preliminary fungitoxicity tests as carried out on new polymerized complexes of aminotriazole with copper acetate (PCC) against Coniophora puteana and Trichoderma viride.
Laboratory tests on wood confirmed the findings arrived at in the screening test on agar medium. Deep penetration into pine wood of compounds studied was observed and particularly so at humidity...

Conforming to european standards for preservative-treated timber: Specifying with confidence
2000 - IRG/WP 00-20194
A four-year collaborative study between four industrial partners and BRE has assessed timber treated by current UK industrial practices in the light of current European Standards. Data were collected for CCA and creosote treated timber components, and compared with the requirements laid out in EN351-1 and -2. A number of difficulties were encountered that have been described in previous IRG papers...

Some aspects of laboratory and field testing methods of antitermite wood preservatives
1973 - IRG/WP 235
Various methods for laboratory testing of antitermite activity of wood preservatives are described. The results of simultaneous tests of three water-borne preservatives, according to the various methods are discussed, and comparison is made with results of field tests on the same three preservatives, showing a fairly good accordance between laboratory results and field results....

Determination of the preventive efficacy against wood destroying basidiomycetes fungi, EN V 839 - CEN/TC 38 WG 9
1993 - IRG/WP 93-20015
The WG 9 of CEN TC/38 has presented to EC a mycological test to assess efficacy of preservatives applied by surface process. This method is now an experimental standard (EN V 839) which has to be approved by the different european delegations. The following paper is not the standard as it has been proposed but is a presentation of the principle of the method. The experimental standard specifies a ...

Inventory of the use of preservative-treated wood and wood preservatives in Sweden 1900-1997
1999 - IRG/WP 99-50137
The objective of this study was to present an overview of the use of wood preservatives and their active ingredients and industrially preservative-treated wood in Sweden since the beginning of the 20th century. The data presented in the report could for example be used as a basis for different waste management scenarios for preservative-treated wood. Before 1960 railway sleepers and utility poles ...
