Window test. Direct testing of wood resistance to decay: A study of its fitness, its reliability and its accelerating factor
1984 - IRG/WP 2219
This is the results of an experiment using the window-test specimens, exposing the specimens to three different types of testing procedure: 1. Natural infestation in the open air; 2. Artificial infestation and exposure in the open air; 3. Artificial infestation in a green-house. The results show good similiraties of the three parallel tests in term of decay, and assess the reliability of the windo...

Comparative study on the leaching of wood preservatives between natural exposure and accelerating laboratory conditions
1999 - IRG/WP 99-50134
Impregnated specimens with CCA, ACQ, and BAAC were subjected to leaching tests. Specimens of 2x2x1 cm3 in size were used for the laboratory leaching test for 10 days according to JIS K 1571. Specimens of 25x1 x1 cm3 were used for outdoor leaching test for 6 months. Total leaching amounts of boron per cm3 of specimens treated with BAAC were 325 µg in the laboratory test and 206 µg in the outdoor ...

Accelerating effects of the field biological attacks in a weather controled soil bed room
1997 - IRG/WP 97-20118
For the purpose of the accelerating the field evaluation of the material service life, a weather controlled soil bed room were designed. The room was controlled 30°C, 75%R.H. In this room, water was sprayed 15 minutes a day. The workers and soldiers of termite, Reticulitermes speratus, can be penetrated. The comparison results of preservative brushing coated treated stakes between field ones and ...
