IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 18. Report of seventh inspection (72 months) in Australia
1984 - IRG/WP 4108
This report includes the results for the 72 month inspection of the IRG/COIPM International Marine Test installed in Sydney Harbour. Although, overall, attack by teredinid and limnorid borers have been most commonly encountered in test specimens at this site, slight attack, mainly by sphaeromatids, has recently been initiated on some hitherto unattacked treated Alstonia scholaris and Pinus sylvest...

1980 - IRG/WP 454
Wood samples (15 x 2 x 2 cm³) were treated with one copper/chrome/arsenic (CCA) and one copper/chrome/boron (CCB) preservative using the following concentrations - O, 3, 6, 10%. Treated samples of three reference wood species - Alstonia scholaris, Fagus sylvatica, Pinus sylvestris were supplied to all participants. Additional local species were chosen by participants and included in the test at t...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 19: Report on the condition of specimens at Sekondi, Ghana after 42 months
1984 - IRG/WP 4109
The results of the first formal inspeation of CCA- and CCB- treated test panels exposed at Sekondi, Ghana, in June 1980, are presented. All untreated control panels of both reference and local species have been destroyed. Of the% CCA- treated specimens, only those of Pinus sylvestris (reference species) and Mitragyna stipulosa (local species) have not been attacked. 3% CCB-treated local species ha...

Information from the COIPM Wood Group
1988 - IRG/WP 4146
Abstract from the COIPM minutes: Wood in marine environment:
Mrs Gambetta stated that the main item discussed by the Group was the collaborative work to test the durability of heat shrinkable polyolephin sheating materials for the protection of wood against marine organisms. The work began last year when wood samples were sent out to the participants. Three samples of Pinus sylvestris wrapped in ...

Information from the COIPM wood group. (With Appendix: Préserver les matériaux en milieu marin sauvegarder l'environment marin telles sont la vocation et la mission du C.O.I.P.M.)
1989 - IRG/WP 4156
During the last COIPM Meeting, up to date information on cooperative work to test the resistance of plastic wrapping for pilings were submitted and discussed. In 1986 untreated wood samples wrapped with shrinkable polyolefin sleeves were submerged in 9 stations, situated in temperate and tropical waters. After 1 or 2 years of immersion the samples showed no sign of penetration by marine borers and...

The status of the Working group on Preservation of Wood in the Marine Environment
1977 - IRG/WP 424
At the last joint meeting of IRG/COIPM members in May 1976 at Wildhaus, Switzerland, a proposal was made that the existing 'Marine Group' should become a formal part of IRG. At present, members of the Wood Group of the COIPM (Comite International Permanent pour la Recherche sur la Preservation des Materiaux en Milieu Marin), and members of IRG who are interested in wood preservat...

International co-operation in wood preservation research
1979 - IRG/WP 3145
If one searched the literature, one could find many examples of international co-operation in the field of research in wood preservation. For example, individual workers in different countries in Europe have got together and made replicate tests with both fungi and insects on various preservatives of common interest and their results have been published. Much co-operation has not had its results p...

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...

Which fungi cause sapstain in Canadian softwoods?
1998 - IRG/WP 98-10285
The Canadian forest products industry suffers considerable losses in revenue due to fungal stains. There is an increased awareness that more complete knowledge about the causal organisms might help solve the problem. A first step was to initiate a thorough survey of bluestain fungi in Canada. Systematic sampling was done at seven selected sawmills in six Canadian provinces. In summer 1997 fresh lo...

Microbiological degradation of wooden piles in building foundations
1988 - IRG/WP 1370
White rot, soft rot and bacterial attack have been detected in softwood piles under buildings. In some cases bacteria were found to be the main degradation organisms in the studied piles. The water content of degraded piles was very high. The compression strength was quite low also in the piles deteriorated by bacteria. The density of wood was very variable, and the degree of degradation could not...
