An interim report on trials with 'Boliden K33' and 'Celcure A' in water of different salinities in the Baltic Sea and in the UK
1974 - IRG/WP 406
It was felt necessary to undertake field trials using large test samples exposed in natural water of different salinity in order to determine preservative leaching and to assess the degree of biological attack....

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....

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...

Moisture condition in treated wood exposed outdoors. A progress report
1989 - IRG/WP 3533
Wood treated with water-borne preservatives, mainly CCA (copper/chromium/arsenic), CCB (copper/chrome/boron) or CC (copper/chrome) is often said among users in Sweden to absorb more water than untreated wood. In laboratory tests this statement has not been confirmed but no field tests have been carried out in Sweden to study this phenomenon. In 1986 a project was started to compare water absorptio...

Co-operative research project on L-joint testing. Progress report to March 1984
1984 - IRG/WP 2211
Each participant was intended to expose L-joints in the main trial on 1 April 1983 and the first sampling, after 8 months exposure, was to be undertaken on 1 December 1983. Some participants have had to vary this schedule. Results are presented from CTFT (France) and PRL (United Kingdom). These show a greater effectiveness by the double vacuum treatments compared with the 1 minute dip treatments. ...

Fungus cellar and field tests with tall oil derivatives. Final report after 11 years' testing
1993 - IRG/WP 93-30007
Two derivatives of tall oil were tested as wood preservatives in a fungus cellar and in ground contact (field test). Stakes of Pinus sylvestris sapwood were used in the tests. For the field test the size of the stakes was 20 x 50 x 500 mm³ and for the fungus cellar test 20 x 20 x 250 mm³. The stakes were vacuum-pressure treated with the two products and exposed in 1981. The field test site used ...

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...
