Health and safety aspects of the use of wood preservatives. Preliminary evaluation of the answers to the IRG-Questionnaire on the state of pollution control in the field of wood preservation
1974 - IRG/WP 56
This preliminary evaluation of the answers to the IRG/WP-Questionnaire only gives a general survey on those questionnaires, which the author received until June 13, 1974. Details, such as correlations between importance of wood preservation and pollution control, could not be considered due to lack of time. For the same reason it was not possible so far, to evaluate the additional remarks given in...

Performance of untreated French Guianan piling in marine exposure
1992 - IRG/WP 92-4173
Round piling of seven French Guianan species, greenheart, and preservativ-treated Southern Pine were installed as fender piling in Key West, FL. After 12½ years, none of the tropical hardwoods performed as well as dual-treated Southern Pine. Of the hardwoods, kouata patou and maho noir were the most resistant to decay and marine borers....

Notes on the resistance of tropical woods against termites
1985 - IRG/WP 1249
This paper deals with a descriptive account on the effect of experimental methods, matrix, species of termites, solid wood and wood extract on the resistance and repellency of woods against three species of termites, i.e. Cryptotermes cynocephalus Light; Coptotermes curvignathus Holmgren and Reticulitermes lucifugus (Rossi). Two methods of experiment were used, the Forced Feeding Test and the Feed...

Study on the treatment of construction timbers by diffusion methods
1983 - IRG/WP 3252
Several species of timber that could be used for constructional purposes have to be pressure impregnated before such use. Pressure impregnation requires expensive equipment, and needs specialized trained operators, etc, which is not possible in most parts of India. Some timbers cannot be pressure impregnated, but can be treated by diffusion. Diffusion treatments could protect these timbers with si...

Treatment of precut timbers
1991 - IRG/WP 3665
A serious lack of house construction technicians has produced a trend in which wooden parts of a house are processed by computer aided precut machine and the precut wood is treated with termiticides and/or fungicides at the plant site. We have developed a new system to handle these requirements of homebuilding. This system is a combination of incising machine, spray machine and proprietary oil-bor...

Natural durability of some commercial timbers of Sarawak, Malaysia in tropical marine environment
2005 - IRG/WP 05-10561
The abundant supply of timber resources in Sarawak makes timber an ideal choice to be used for marine construction. The natural durability of the main commercial timber species of Sarawak in ground contact is well established but the same is not available for marine environment.
This study was conducted to assess the natural durability of 28 commercial timber species in tropical marine environmen...

Some relationship between physical characteristics and treatability of Bolivian woods
1987 - IRG/WP 3434
Using the available data on physical characteristics of 25 Bolivian woods, some relationships between porosity, specific gravity and treatability (hot and cold open tank process with 5% pentachlorophenol) were analysed. The aim of this report is to give information on technical characteristics of Bolivian hardwoods which have been studied in this country by Centro de Desarrollo Forestal and in Per...

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....
