Soil virulence tests using Scots pine sapwood
1973 - IRG/WP 222
Following the tests reported in Document No: IRG/WP/210, in which soils from different laboratories were investigated for virulence, supplementary tests have been carried out using Scots pine sapwood and an extended incubation period....

Collaborative tests on the influence of solvent and drying method on the toxic limit of wood preservatives against Basidiomycetes
1974 - IRG/WP 248
Seven institutes from five countries, Austria, England, France, Germany and the Netherlands have collaborated in a study on the influences of solvent and drying method on the toxic limits of wood preservatives against Basidiomycetes tested according to the agar-block method. Two preservatives, a 25% pentachlorophenol-concentrate and tributyltinoxide were applied to pine sapwood and beech and teste...

Wood preservation in East European countries
1989 - IRG/WP 3527
The paper discusses the main problems of wood preservation in Bulgaria, Czechoslovakia, German DR, Hungary, Poland, Rumania and the USSR. The main types of wood preservatives produced have been presented, as well as the state of standarization to test their properties. There have been considered methods of wood treatment in use and application range of treated wood....

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...

Collaborative soft rot tests: Tests conducted at Princes Risborough and Delft on soil samples from collaborating laboratories
1972 - IRG/WP 210
The laboratories which took part in the original collaborative soft rot test (Savory and Bravery, Holz u Org 5 (1) 58-90, 1970) sent samples of the soil used in the original test to Princes Risborough. Portions of this material were sent to Dr Hof for soil analyses at TNO and the remainder was employed at Princes Risborough for the conduct of comparative tests of soil virulence when used as a comb...

Collaborative soft rot tests: Statistical treatment of results of soil analyses
1971 - IRG/WP 29
Institutes taking part in the collaborative experiments already reported forwarded samples of the soils employed in the tests to the Forest Products Research Laboratory, England. The soils were then autoclaved sterilised under uniform conditions and sent to the Department of Forest Soils, the Royal College of Forestry, Stockholm, Sweden. The results of the soil analyses are given in Table 1, toget...

Wood Preservation in Belgium
1981 - IRG/WP 3170
The report reviews wood preservation activities in Belgium and notes the number of authorized treatment depots has doubled during the past five years. It lists the timbers that are allowed to be used for joinery and constructional building purposes and the preservatives and treatments with which these timbers may be protected. In Belgium not only have the wood preservative product and its treatmen...

Wood preservation in Brazil
1978 - IRG/WP 3126
Wood preservation was stablished in Brazil by 1902 in order to provide treated sleepers for railways, since there was a shortage of durable hardwoods in area served by railways. The growing need of sleepers and poles together with the availability of Eucalyptus spp. contributed for the development of wood preservation. Many wood preservation plants started to be stablished in 1957, and in 1977 the...

Further discussion of biological durability assessments of acetylated wood from several European institutes
2006 - IRG/WP 06-40340
In the last decade, interest in the development of wood modification systems has increased in Europe. Alongside several industrial initiatives for heat treatments, there have also been scaling up and pilot plant projects for chemical wood modification. Between 2000-03, the European Commission funded the "Thematic Network on Wood Modification". This paper features a re-evaluation of work undertaken...
