Sampling rates and the probability of detecting defective treatment in the sampling of preservative treated timber
1987 - IRG/WP 2277
When attempting to enforce standards of penetration and retention set for treated timber, the regulating authority must establish a sampling or inspection scheme which will prevent large quantities of substandard product entering the market. On the other hand, the scheme should not penalise treaters for the small quantities of such material which are inevitably produced by any industrial process. ...

The growth and behaviour of Australian isolates of dry rot fungi, mainly Serpula lacrymans (Schum. ex Fr.) S.F. Gray. A comparision with the world literature
1983 - IRG/WP 1190
In Australia Serpula lacrymans occupies a rather unique environment, being restricted to growth within basal regions of buildings containing masonry. Its rate of timber attack in these situations appears to be far faster than that experienced in other parts of the world. Therefore the question arises as to how Australian isolates (particularly 16508 which has become a "standard" test fungus for so...

A below-ground exposure method for determining the resistance of woody and non-woody materials to attack by subterranean termites
1993 - IRG/WP 93-10012
With existing field test procedures, in which specimens are installed vertically to some of their length into the ground and spaced out from each other ("grave-yard" tests), variations in the rate of contact by termites between replicates can be common. Mechanical damage to specimens during inspection and re-installation may also be difficult to avoid. A new field test method, evaluated in Austral...

Comparison of three methods for assessing the in-ground termite resistance of treated timber, durable timber and plastics at sites in Australia, USA and Thailand - First results
1998 - IRG/WP 98-20132
The in-ground resistance of materials to attack by subterranean termites is most commonly assessed with one form or another of the conventional graveyard method, despite the significant shortcomings of this method. In Australia, an alternative method, in which all samples of test materials are placed below-ground, has been in use for more than 10 years. The method provides reliable exposure of sam...
