Report of field test results for dichloro-n-octyl-isothiazolone: A potential new wood preservative
1988 - IRG/WP 3495
In a previous report (IRG/WP/3306) we presented preliminary laboratory test results on 4,5-dichloro-2-n-octyl-4-isothiazolone (RH 287). Laboratory data indicated toxic threshold values for RH 287 ranging from 0.37 to 0.50 kg/m³. In this report we present field test results on an IRG L-joint test and an in-ground stake test for RH 287, pentachlorophenol and biocide free test units. (a) L-joint tes...

On the use of % weight loss as a measure for expressing results of laboratory decay experiments
1992 - IRG/WP 92-2394
It is suggested that careful consideration should be given for the presentation of data from laboratory decay experiments, especially when comparisons are being made from experiments involving wood blocks of varying densities. Percent weight loss can be used for comparisons of durability even if wood blocks vary in density. It is suggested that the absolute weight loss for a given volume (g/cm³) ...

In ground contact field trial results of preservative treated incised and unincised spruce
1996 - IRG/WP 96-40076
Field trials of treated spruce stakes have been demonstrated that incising the stake before treatment improves the preservative uptake both for CCA and creosote. This results in a substantially extended service life for the incised stakes over the unincised stakes for preservative concentrations at commercial levels. After 24 years in ground contact the majority of incised spruce samples are sound...

Termite field test results of preservative treated and modified woods in Kumamoto, Japan
2001 - IRG/WP 01-30275
Various preservative treated or modified wood stakes other than CCA, were buried in the soil, maximum for six years in Kumamoto, south west side of Japan. In this area, two main termite species, Coptotermes formosanus and Reticulitermes speratus, are distributed. After two years in field, untreated sapwood of sugi (Cryptomeria japonica) were observed severe attacks by termites, but the preservativ...

Field Test Results after Nine Years for CCA and ACQ Preservative-treated Wood Fixed in Different Climates
2003 - IRG/WP 03-30303
During assessment of the ground contact stakes in the Norwegian test field, we have frequently found that the first visual rot attack is in the zone of the stakes, where the stakes have been in contact with each other during the fixation. These parts are usually light green, caused by the lack of light during fixation, compared to the rest of the stake surface, which has a darker colour.

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...

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...

Questionnaire: Facility for accelerated stake tests in unsterile soil
1981 - IRG/WP 2166
An acceptable name for this type of test facility has not yet been devised, but it has previously been referred to as a FUNGUS CELLAR or as a TROPICAL DECAY HOUSE. The attached pamphlet (What's New in Forest Research No.65) describes in broad terms the facility used for this purpose at FRI in New Zealand. Over the last two or three years several laboratories and commercial firms have inst...

Assessment of wood preservation facilities in Canada
1989 - IRG/WP 3557
This document sets out an assessment procedure for the current status of the wood preservation industry in Canada in relation to the Technical Recommendations (TR) documents for the Design and Operation of Wood Preservation Facilities published by the Government of Canada in April 1988. A questionnaire has been prepared in consultation with industry and the Canadian Institute of Treated Wood. An a...

Answers to the questionnaire on Gloeophyllum trabeum ( = Lenzites trabea)
1972 - IRG/WP 107
In the Working Group I of the IRG it was agreed to prepare monographic cards of wood destroying fungi. In first instance three fungi, amongst which Gloeophyllum trabeum, were chosen to start with. A questionnaire was drawn up by Prof. C. Jaquiot and the members of the IRG were asked to give information on Gloeophyllum trabeum in accordance with this questionnaire. The results of this enquiry are g...

Water-borne wood preservatives against marine borers. Results from NWPC marine trials started in 1972 and 1976
1990 - IRG/WP 4162
The paper presents the results from NWPC (Nordic Wood Preservation Council) marine trials started in 1972 and 1976. The trials are carried out according to the NWPC Standard No. 1.4.2.2./73 "Marine test - a test against marine wood boring organisms in sea water". The test site is Kristineberg Marine Biology Station on the west coast of Sweden. The wood blocks used in the trials were made from sapw...

Co-operative field trial. Background notes and questionnaire for field sites
1992 - IRG/WP 92-3733
The first co-operative field trial was designed to study the occurrence of soft-rot in CCA treated hardwoods. Generally speaking very similar results were obtained from the different field sites. In the early part of the trial considerable variability was evident with regard to the rate and type of attack which occurred in the untreated material. With the CCA treated timber the type of decay was p...
