This study, which promised remarkable contributions for designing of experimental samples and trial device to treat wood by pre-vacuumed immersion method, was conducted to test the impregnability of wood material according to the pre-vacuumed immersion process and to reveal the usability of plug (cylindrical) samples in impregnation experiments in addition to the cuboid (rectangular prism) samples. In this perspective, samples to be subjected to immersion test were initially dried to an average moisture content of 12% and than prepared for the flow pathways to determine the possible preservative uptake as the percentage of void volume filled and net dry salt retention in radial and longitudinal flow pathways, and in triplex [i.e. three flow pathways including tangential flow] and than impregnated using with 3% concentration of boron compound by normal and pre-vacuumed immersion method based on the immersion of 120 minutes, and pre-vacuum process of 30 minutes at –0,84 bar (640 mmHg). According to the experimental evidences that have been provided, it was observed that the preparation techniques for cuboids and plugs were suitable with each other in terms of the preservative uptake in either flow pathway, while the preparation process and the period of the data collection were shorter in plugs than that for cuboids. And samples impregnated by pre-vacuumed immersion method were determined to have a slightly higher preservative uptake than those impregnated with normal immersion method. At this point, it was also observed that in both experimental arrangements, the level of preservative uptake was minimal in radial samples compared to longitudinal samples. Therefore, based on the outcomes of this study, some remarks and recommendations for future work can be deduced on the use of plugs and cuboids, and also pre-vacuumed immersion process in the context of permeability examinations of any wood material.
