Review of candidate graded particle barrier testing methods in Australian Standard (AS 3660.3 – 2000): Assessment criteria for termite management systems
2009 - IRG/WP 09-20417
The Australian Standard (AS. 3660.3 – 2000) for assessment of candidate graded particle termite barriers is reviewed and suggestions for amendments are made. Areas requiring amending in light of current biological knowledge involve the inclusion of proprietary or patented systems rather than generic types; selection of test termites in the genus Coptotermes; duration of test periods; and inadequ...

Managing termite risks – An Australian perspective and a cautionary tale
2012 - IRG/WP 12-20482
The management of the risks of termite attack on new buildings in Australia falls to a range of agencies and is mostly achieved through controlling the process by which structures are certified as complying with the Building Code of Australia. Australian Standard AS3660 parts 1, 2 & 3 have historically been the core of this function but now the Building Codes Board's own certification scheme,...

Effect of a Water Repellent Treatment on Moisture Behavior of Three Australian Hardwoods: A Preliminary Report
2021 - IRG/WP 21-40921
Wood is inherently hygroscopic and will sorb moisture either directly from the atmosphere or via capillary action. Moisture can have marked effects on wood properties and repeated wetting and drying creates dimensional changes that lead to physical damage. Exposure to elevated moisture levels also increases the risk of fungal attack. Wood preservatives have long been used to minimize the risk of ...

Susceptibility of selected Australian commercial timbers to West Indian drywood termite Cryptotermes brevis
2023 - IRG/WP 23-11003
West Indian drywood termite (Cryptotermes brevis) is a globally distributed timber pest and is invasive in Queensland, Australia, causing widespread damage to structures and large economic impacts in control and repair costs. Despite this, the knowledge of which specific timbers are susceptible to attack is limited and requires investigation. Two six-week feeding trials were performed, exposing se...

Australian timber durability research needs
2023 - IRG/WP 23-50385
Australia was once a world leader in timber durability research, but prolonged disinvestment resulted in a gradual decline in capacity. Forest and Wood Products Australia recognized this problem and supported the development of the Centre for Timber Durability and Design Life to help reverse this decline and begin to educate the next generation of Australian researchers. The Centre is a collabor...
