Amines – Promising Wood Preservatives
2002 - IRG/WP 02-30287
Environmental concerns require a new approach in the field of wood protection. Band of many traditional wood preservatives has lead to intense researches for new environmental-friendly wood preservatives. Amines seem to be promising substitutes for classical biocides. Fungicidal and leaching resistance as well as some other chemical analysis of beach and Norway spruce samples treated with ethanola...

Status of wood preservation in India
2005 - IRG/WP 05-30386
Wood, despite the advent of other modern materials, continues to play an important role in man’s day to day life. Usage of wood ranges from fuelwood to engineered wood products and demand for it is increasing which has resulted in depletion of forests and diminishing wood supplies. Future needs are required to be met from plantation timbers after adopting processing technologies for their life...

Changes to New Zealand Timber Treatment Specifications
2004 - IRG/WP 04-20288
Changes have been made to the New Zealand timber treatment specifications in response to frequent incidences of decay in framing timber and doubts about the long-term performance of tributyltin formulations when used in exposed situations.
Changes have been made to Hazard Class H1 to allow a level of treatment to provide short to medium decay resistance to framing which would protect it, should l...

Laboratory evaluation of fipronil (a phenyl pyrazole) as a candidate termiticide in the protection of wood against the subterranean termite, Coptotermes acinaciformis (Froggatt) Rhinotermitidae
1997 - IRG/WP 97-10225
In this laboratory evaluation, radiata pine wood blocks (50 x 25 x 15 mm3) were impregnated with fipronil (a phenyl pyrazole) at various concentrations (0, 5, 10, 20, 40, 80, 100 and 200 ppm). Half the treated blocks underwent a leaching schedule for 5 days, while the remainder were unleached after treatment. Five replicates per treatment regime were presented to the test termite, Coptotermes acin...

Wooden windows, avoidance of damage via constructional measures
1990 - IRG/WP 3591
Increasing awareness of the environment reinforces the trend to use wood as a building material for windows in modern building constructions. Wood is a natural building and construction material. Under certain circumstances such as persistent humidity exceeding 30%, wood is rapidly degraded by decay fungi into CO2 and inorganic salts. The cost caused by damage (e.g. replacement of windows) represe...

Wood preservative development: Have we learnt anything, and where will it take us?
1994 - IRG/WP 94-30054
This paper addresses the disparate approaches to the development and approval of wood preservatives used in a number of regions, and the implications of the test requirements, or lack thereof, on the likely performance of the subsequent treated wood in service. The test methodologies and performance criteria used in various regions will have long term consequences for the future of the wood preser...

Canadian code of good practices - Recommendations for design and operation of wood preservation facilities
1990 - IRG/WP 3582
The rationale and procedures for the development of a set of recommendations for design and operation of wood preservation facilities in Canada are discussed. Multi stake holders involvement in problem identification, problem assessment, state of the art knowledge database, implementation and periodic assessment procedures are important considerations for the successful development of a Code of Go...

Practicability of bioassays in the evaluation of environmental risks in wood protection
1996 - IRG/WP 96-50071
As an example for the proofing of the practicability of bioassays in the evaluation of environmental risks in wood protection the ecotoxicological behaviour of CCF-impregnated timber was examined. After vacuum pressure impregnation specimen from shaped pine poles were tested on ecotoxicological effects of leachable compounds using sensitive aquatic organisms like fish, Daphnia and algae as bioindi...

Issues Facing Wood Preservation in New Zealand Today
2003 - IRG/WP 03-30326
In New Zealand, the three major issues facing the wood preservation industry today are:
Extension of use of LOSP preservatives, chiefly tributyltin naphthenate, for treatment of products in Hazard Class H3 exposed to the weather for which LOSP have not been traditionally used. Concerns have been expressed about the long-term durability of such products.
Restrictions on the use of CCA preservativ...

Resistance of Teak, Balau, keruing and Chengal Wood species against marine borers attack
2004 - IRG/WP 04-10513
Wood samples of Teak (Tectona grandis) , Keruing (Dipterocarpus alatus),Yellow Balau (Shorea laevis) and Chengal (Balanocarpus heimii) were treated by Creosote, using Ruping method. The dimension of samples were 200 x 75 x 20 mm and the retention were 188, 186, 331, 40 kg /m3 respectively. Both treated and untreated samples were installed in sea water (Mahshar in Persian gulf and Bandar Torkman an...

1997 - IRG/WP 97-40089
From the economical point of view, increasing the lumber durability by the application of preservative treatments is very important. In this study, samples were randomly selected from Fagus orientalis Lipsky., Carpinus betulus L. and Populus deltoides Bartr. in two forms (Board & Squared cross-section) and have been treated with ACC & CFK by using Dipping & Bethel methods. The matched ...

Determination of fixation properties by bioassays - A proposal for the assessment of safety indexes in wood protection
1990 - IRG/WP 3566
In the determination of environmental effects of chemicals tests with fishes, daphnia and algae have proved to be practicable. With respect to wood protection such bioassays are suitable to control effects of treated timber against aquatic organisms. By using the fish-acute-toxicity-test the development of a laboratory test method is described for the checking of the fixation rate of a copper-chro...

Efficacy of linear chain carboxylic acid anhydrides as wood protection chemicals
2002 - IRG/WP 02-30295
This paper presents an assessment of the effectiveness of linear chain carboxylic acid anhydrides namely, acetic, propionic, butyric, valeric and hexanoic anhydride, in improving the decay resistance of Corsican pine (Pinus nigra Schneid) sapwood. Wood-anhydride bond formation was verified by the increase in sample weight and volume. A brown rot fungus
[Coniophora puteana (Schum.:Fr)] was selec...
