Fungus cellar and stake tests with tall oil derivatives. Progress Report after 5 years' testing
1987 - IRG/WP 3442
Two derivatives of tall oils have been tested for five years in fungus cellar and stake tests. The samples were relatively quickly attacked on the surface by decay fungi, mainly soft rot, but the decay has progressed very slowly. The performance of the stakes in the tests has so far been equivalent or even better than some CCA preservatives and creosote....

Reticulitermes (Ins., Isopt.) in Central and Western Europe
1969 - IRG/WP I 5A
Reticulitermes flavipes (Kollar) has established itself in Hamburg and Hallein coming from the east of North America. In France, on the northern boundary of termit occurrence, Reticulitermes santonensis are distinguished from Reticulitermes lucifugus by special activity and resistance. According to comparative investigations with colonies of several Reticulitermes species of different origins rega...

A critical review of the AWPA standard method (M12-72) for laboratory evaluation to determine resistance to subterranean termites
1986 - IRG/WP 1298
The American Wood Preservers' Association standard (M12-72) for evaluation of candidate wood preservatives against subterranean termites is reviewed and suggestions for revision are made. The most serious flaws in the current test procedure involve a failure to recognize inter- and intraspecific variation and a lack of quantification of test results....

Health and safety aspects of the use of wood preservatives. Preliminary evaluation of the answers to the IRG-Questionnaire on the state of pollution control in the field of wood preservation
1974 - IRG/WP 56
This preliminary evaluation of the answers to the IRG/WP-Questionnaire only gives a general survey on those questionnaires, which the author received until June 13, 1974. Details, such as correlations between importance of wood preservation and pollution control, could not be considered due to lack of time. For the same reason it was not possible so far, to evaluate the additional remarks given in...

Reticulitermes (Ins., Isopt.) in Mittel- und West-Europa
1969 - IRG/WP I 4
In Hamburg und Hallein hat sich Reticulitermes flavipes (Kollar) aus dem Osten von Nordamerika eingebürgert. An der Nordgrenze des Termitenvorkommens im Westen Frankreichs zeichnet sich Reticulitermes santonensis Fetaud gegenüber Reticulitermes lucifugus durch besondere Aktivität und Widerstandsfähigkeit aus. Nach vergleichenden Untersuchungen an Kolonien verschiedener Reticulitermes-Arten meh...

Evaluation of polystyrene as a protective of wood in sea-water
1986 - IRG/WP 4129
A test is described on the biological protection of wood by treatment with polystyrene. The results, obtained in marine trials, after 18 months, show that the treatment with polystyrene is not all that effective in preventing the attack of marine borers....

A standardised procedure for the treatment of timber with test chemicals
1986 - IRG/WP 2257
A procedure is described which allows the standardisation of sample handling and data manipulation during trials invastigating the treatability of timber with test chemicals. The use of computer software allows the data to be handled efficiently....

Co-operative research project on L-joint testing. Progress report to May 1989
1989 - IRG/WP 2338
Further sets of data received from STU (Sweden) after 36 months exposure and Sipad-IRC (Yugoslavia) after 45 months exposure are presented and discussed in conjunction with data reported previously. The new data are generally in agreement with those presented previously and the major difference between institutes continues to be one of rate of colonisation rather than any relative difference in pe...

Laboratory evaluation of phoxim in plywood
2001 - IRG/WP 01-30264
Two types of phoxim treated plywood bonded by phenolic resin glue and urea resin glue were challenged with termites of Coptotermes formosanus Shiraki in laboratory. It was found that the sawdust of phoxim treated plywood bonded by phenolic resin glue was not active or did not kill termites of Coptotermes formosanus Shiraki within the test period. Moreover, the phoxim treated plywood bonded by phen...

A natural exposure weathering test for the evaluation of preservative performance
1992 - IRG/WP 92-2400
Natural exposure weathering tests were carried out by externally exposing treated wood samples for varying periodes of time up to 36 months. In the laboratory these samples were assayed for residual preservative effeciveness using Coniophora puteana FPRL 11E. The results indicated a loss in efficacy over and above that determined using artificial ageing procedures such as EN73 (evaporative ageing)...

The preliminary evaluation of selected sulfonium salts for use in wood preservation
1984 - IRG/WP 3278
Five sulfonium compounds, including two sulfonium methosulfates, one sulfonium bromide and two amphoteric sulfonium propanesulfonates, were prepared in crude form and subjected to various biocidal screening tests. A rapid screening test in which treated Pinus radiata pulp pellets were exposed to one of three wood-decaying fungi growing on malt agar revealed that dodecyl dimethyl sulfonium methosul...

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...
