Report on the co-operative leaching tests
1975 - IRG/WP 246
The Work reported here was undertaken at the request of CEN to see (1) whether the standard beaker leaching method under discussion at CEN, and based on the German DIN could be made less labour intensive; and (2) whether the leaching parameters could be expressed in more general terms so that alternative procedures could be used. A co-operative experiment was set up in which the amount of leaching...

Determination of toxic limits of wood preservatives towards wood-destroying Basidiomycetes. Investigation on the effect of the use of two impregnated wood blocks and of one impregnated and an untreated block respectively in Kolle jars on the toxic limits of wood preservatives

Giftwirkung einiger organischer Zinn-Verbindungen auf Eilarven von Hylotrupes bajulus (L.). [Toxic efficacy of some organic tin compounds against egg larvae of Hylotrupes bajulus (L.)]
1978 - IRG/WP 2120
The toxic values of 12 organic tin compounds towards newly hatched larvae of Hylotrupes bajulus were determined after 4- and 12-week test periods in comparison with bis-tri-n-butyltin oxide (TBTO). Tri-n-butyltin benzoate as well as the 2-, 3- and 4-methyl benzoate of tributyltin oxide were equally effective as TBTO and the latter two were somewhat more effective after a 12-week test period. Almos...

Observations on preservative penetration in poplar
1991 - IRG/WP 3662
In the course of studies on the CCA treatment and durability of poplar timber a zone of refractory wood at the sapwood/heartwood boundary was observed. Further studies were conducted to investigate the causes of this refractory behaviour. The initial results have suggested that the presence of lipid storage products in the ray tissue may lead to impermeability, either by directly blocking pits or ...

Furfurylated wood – withdrawal load for fasteners
2007 - IRG/WP 07-40381
The withdrawal load for hot dip galvanized nails and chromated decking screws in furfurylated Baltic redwood (Pinus sylvestris) with a Weight Percent Gain (WPG) of approximately 40 % was measured according to DIN 1052. The average withdrawal loads were 60-100 % higher for the nails and approximately 20 % higher for the screws in the furfurylated wood compared to untreated wood. The results ind...
