Japanese Classification of Wooden Building Members for ISO Use Classes according to the Building Code in Japan.
2006 - IRG/WP 06-20337
Because of the international approve of use class system for the biological degradation of wood by ISO/DIS 21887 and ISO/DIS 21892, Japanese committee of ISO/TC165/SC1 asked to the JWPA for classify the wooden commodities by use class of these draft ISO. The JWPA was prepared a draft use class model in Japan. Japanese building code systems are described and Japanese draft use class system is also ...

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...

Estimation of oral toxicity of boron as a bait toxicant and the trophallactic effects between individual members of termite colonies.
2003 - IRG/WP 03-10495
In recent years, because of the favourable environmental characteristics of boron, researchers in the wood preservation industries have refocussed on the use of boron as a major wood preservative against wood-destroying insects. Currently the greatest use of boron compounds is in remedial treatments.
Boron has been found to have slow-acting toxicity against subterranean termites. Because of thi...

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...

Influence of preservative treatment on the glueing of the members of glued laminated frames and effectiveness with respect to newly hatched larvae of the house longhorn beetl
1971 - IRG/WP 203 E
The object of the work is to check the general properties of a glued laminated beam after treatment of the members composing it by means of commercial insecticidal and fungicidal formulations in clear solvent under the most common conditions of manufacture. The species used have been spruce, redwood and Douglas fir in planed boards of 80 cm long, 14 cm wide and 20 mm thickness at about 12% moistur...

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 ...

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 ...

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...

What is OECD doing to promote harmonization of biocide regulations
1999 - IRG/WP 99-20182
OECD began work on biocides in 1997 to help Member countries co-operate in the assessment and registration of these products. The work is a part of OECD's Pesticide Programme, and is co-ordinated by the Biocides Steering Group. The goal is to harmonize regulatory approaches to allow countries to conduct evaluations of biocides more efficiently. More efficient evaluations can advance the p...
