To decay or not to decay: An accelerated field test of the validity of the Scheffer index
2008 - IRG/WP 08-20392
…Scheffer Index value implies a greater risk of decay. An accelerated 18-month study using seven field sites with Scheffer Indices ranging from 35 to 400 and two wood types (Populus tremuloides and Pinus spp.) was used to test the validity of the Scheffer Index. Different measures of decay including visual ratings,…

Accelerated Above-ground Testing of Wood Preservatives
2007 - IRG/WP 07-20358
…Pest Management Regulatory Agency requires data from field tests under Canadian conditions but these can take many years to generate results. Forintek has therefore developed an accelerated above ground test, under contract to a variety of clients. This paper focuses on the test method and provides examples of…

Electrokinetic Accelerated Ingress of Boron After Surface Treatment of Wood
2007 - IRG/WP 07-40372
…of boron in wood samples that was subjected to an electric field, compared to penetration based on diffusion. The boron is expected to move as boric-tartaric acid complexes, which is in agreement with transport towards the anode. The acceleration was evident both in transport along the grain and in the radial…
