International collaborative laboratory comparison of two wood preservatives against subterranean termites: Third update and first report
1996 - IRG/WP 96-10174
At the 24th annual meeting of IRG in Orlando, USA, in May 1993 an international subterranean termite laboratory bioassay to compare the various preferred termite protocols used by IRG termitologists was initiated. The author was nominated to co-ordinate this comparative laboratory evaluation of two wood preservatives, copper-chrome-arsenic (CCA) and copper naphthenate (Cu-Na) against the subterran...

Collaborative field experiment: Analysis of copper and chromium in stakes of the four reference timbers
1982 - IRG/WP 3213
The stakes analysed belong to the Swedish set of the four reference timbers of the collaborative field experiment (Document No: IRG/WP/367). Before the field exposure 60 mm were cut off the end of each stake. This was done in order to be able to carry out chemical analyses as well as different types of testing. Some of the material has been used in softrot tests (Document No: IRG/WP/1151)....
A collaborative test to determine the efficacy of polyurethane coatings on wood samples exposed in the marine environment
1984 - IRG/WP 4113
Aims are: a) to determine the effectiveness of elastomeric polyurethane as a protective coating against marine wood boring animals in a range of tropical and tempreate sites; b) to compare the adhesion of polyurthane coatings on different wood species exposed in seawater; c) to record the severity of attack in failed samples and to identify the causal marine organisms....

Collaborative soft rot test: Amended test method
1972 - IRG/WP 208
The initial draft of a standard test method (Document IRG/WP/201) was discussed at the meeting in Brussels in 1971. It was agreed that a revised draft should be prepared and that the Princes Risborough Laboratory (formerly FPRL) should conduct a trial test using the method as a preliminary to the main collaborative test....

IRG soft rot stake test. Site: 03 Australia. Progress repor
1980 - IRG/WP 1114
IRG soft-rot test stakes were installed in site 03 Australia 16.6.77. The stakes have been inspected twice, (28.11.78 (Johnson, 1979) and 31.10.79) for signs of decay, and used to obtain fungal isolates. The condition of stakes in the supplementary soft-rot test has also been examined....

Co-operative field experiment. Performance of preservative-treated hardwoods with particular reference to soft rot: Report of condition of specimens installed in Victoria, Australia
1978 - IRG/WP 3118
A collaborative test to determine the efficacy of poyurethane coatings on wood samples exposed in the marine environment. 1st Interim Report
1988 - IRG/WP 4145
Wood samples coated with elastomeric polyurethane (ca. 50 mils thick) were exposed for up to 2 years in 12 tropical and temperate marine test sites with known teredinid, pholad and/or crustacean infestations. All uncoated control samples were destroyed or partially destroyed. Polyurethane-coated samples were not attacked, the surfaces of the coating were sound and the polyurethane adhered well to ...

Final proposals for a field experiment to determine the performance of preservative treated hardwoods with particular reference to soft rot
1976 - IRG/WP 367
A series of hardwood stakes have been prepared and treated in the UK from samples (mainly sapwood) supplied from participants around the world. The stakes include 4 reference species common to each site and, in most cases, at least 2 local species of importance. The treated stakes will be despatched to the co-operating scientists and installed under local conditions. It is hoped that with periodic...

A collaborative test to determine the efficacy of polyurethane coatings on wood samples in the marine environment. 2nd Interim Report
1990 - IRG/WP 4161
The results of a collaborative international test to evaluate the performance of elastomeric polyurethane coatings of wooden test samples exposed in seawater at 13 sites around the world are reported. The samples have been exposed at sites with known infestations by molluscan and/or crustacean wood borers. Performance data for up to 4 years exposure at some sites is presented providing information...

Collaborative field trial out-of-ground contact
1982 - IRG/WP 2179
At the 12th meeting of the IRG in Sarajevo, Yugoslavia it was decided after considerable discussion that the best way to proceed with the work of the subgroup was to centre it around a co-operative field trial based on the L-joint test detailed in IRG/WP/2157. At the same time it was agreed that interested laboratories would also conduct their own methods, particularly the German planner test and ...

A collaborative test to determine the efficacy of polyurethane coatings on wood samples in the marine environment. 3rd Interim Report
1993 - IRG/WP 93-10046
The results of al long-term marine trial to assess the protective effect of polyurethane coatings on wood samples exposed at different sites around the world are reported. The condition of samples exposed in the sea for up to 88 months was generally sound, although instances of marine borer infestation were reported at two sites. At one site, mechanical damage of a non-biological nature is believe...

IRG/COIPM INTERNATIONAL MARINE TEST - To determine the effect of timber substrate on the efectiveness of different preservatives in sea-water: Coding scheme
1976 - IRG/WP 420
It was agreed in Wildhaus on 15 May 1976 that preparations for the test detailed in Document No: IRG/WP/414 should commence immediately, but that initially only two water-borne preservatives should be used - a copper/chrome/arsenic (CCA) and a copper/chrome/boron (CCB) formulation respectively. PRL, England (R Cockcroft) would be responsible for supplying only the reference species treated with th...

CCB, TCMTB and AAC treated IUFRO stakes. A visual on-site assessment of decay type on every test stake was made and observations confirmed by microscopical examination. Regression analyses were used to de...
