Proposals for a field experiment to determine the performance of preservative treated hardwoods with particular reference to soft rot
1975 - IRG/WP 342
It is proposed to treat a series of hardwood stakes in the UK and install them in different sites around the world. The stakes will include 3 reference species common to every site and 2 locally selected species. The hazard of termites should be avoided in order to limit the study to action of micro-organisms....

Soft-rot problems with treated hardwoods: A paper for discussion and establishment of a programme of work
1974 - IRG/WP 331
At the 5th meeting of IRG in Lahti (June 1973) it was decided that an ad hoc group should be formed to study these problems. It was decided that it's activity could be usefully directed in two main areas; a) in the encouragement and direction of existing research in this field, and b) in the organising of a collaborative field trial involving interested parties using locally important har...

Status of the Working Group on Preservation of Wood in the Marine Environment - Questionnaire results
1977 - IRG/WP 434
At the joint meeting of the IRG and COIPM dealing with preservation of wood in the marine environment, it was suggested that a Marine Group should be formally recognised within IRG. It was agreed that a questionnaire (Document No: IRG/WP/424) should be circulated to determine the views of the membership on the future status of this group. The results of this questionnaire are presented....

A status report on code of good practices
1991 - IRG/WP 3679
Code of Good Practices - Anti Sapstain documents, presented to IRG meetings in the past, are the basic documents for health and safety of the workers and the environment in Canada. The BC Ministry of Environnment has now issued regulations in the area of effluent discharge. While Pentachlorophenols (PCP) are not used by the industry, the documents are still used as a guideline document for the oth...

Resolution from IRG Working Group II Sub-group 4 'Stain in timber in service'
1984 - IRG/WP 2230
Sub-group 4 of IRG Working Group II has completed a series of studies of artificial weathering as an alternative to natural weathering in relation to testing the efficacy of chemicals in preventing blue stain in service. The Sub-group reports that within the limits of the equipments studied and described in its report Document No: IRG/WP/2215 the extent of blue stain varied little as a direct cons...

Collaborative soft rot tests: Paper for discussion in Working Group II
1970 - IRG/WP II 5A
An account of the major part of the collaborative work on laboratory tests of toxicity of preservatives to soft rot fungi initiated by the European Homologation Committee at Delft in 1966 has been published in ‘Material und Organismen’ (1970) as a report of progress. The main objective of these collaborative tests, namely to establish a reliable and acceptable standard test method was not acco...

Standardisation of sapstain tests - A challenge
1992 - IRG/WP 92-2403
In the last decade many new anti-sapstain products have been tested world-wide under laboratory and field conditions. Several extensive test programmes have been executed with different non-standardized test methods and procedures, with the result that the biological findings cannot be compared with each other. In this paper, gathered recommendations will be given in order to standardize test meth...

Environmental risk assessment of treated timber in service: The Environment Focus Group approach
2000 - IRG/WP 00-50162
In the context of the Biocidal Products Directive (98/8/EC), and of the OECD work on wood preservatives, the Environment Focus Group (EFG), comprising 8 institutes and the European Wood Preservative Manufacturers Group, has been working on the environmental risk assessment of treated timber in service. A literature review of emissions from treated timber has revealed that very little existing data...

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 5: Interim report
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...

Hardwood Field Experiment: Progress Report 1977-1986
1986 - IRG/WP 3391
The international hardwood field experiment was planned in l976 and set up in same 30 different sites around the world. The test stakes include 4 reference species common to each site and in most cases at least 2 species of local importance. It was hoped that a picture of performance of a range of economically important species would be built up and at the same time provide vital background inform...

FTIR characterization of copper ethanolamine - wood interaction
1999 - IRG/WP 99-20154
The interaction of copper ethanolamine (Cu-EA) and wood components was studied by using Fourier transform infrared spectroscopy (FTIR). In Cu-EA treated wood, significant reduction was noticed on the band attributed to carbonyl vibration from carboxylic groups at 1735±5 cm-1 and an increase in band intensity was obtained from carbonyl in carboxylate at 1595±5 cm-1. The same observation was made ...

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...

Blue stain in timber in service. Progress review of Sub-group collaborative tests - 1981/82
1982 - IRG/WP 2178
Following from the discussions after reporting Document IRG/WP/2146 at the Meeting in Sarajevo, 1981, it was decided that 1.) more precise definition was needed of the artificial weathering schedules used in the work - participants to re-check Table 8 and send further details or amendments to Dr Bravery; 2.) a further test employing a wider range of chemicals was necessary using a smaller range of...
