Abstract
Water absorption differences between sapwood and heartwood of Scots
pine and Norway spruce heat-treated at temperatures 170°C, 190°C, 210°C and
230°C were investigated. The results were compared to industrially
kiln-dried reference samples. Water absorption was determined with a floating
test based on the EN 927-5 standard. Generally, the heartwood of both wood
species absorbed less water than sapwood. Heat-treatment evidently decreased
the water absorption of spruce and pine heartwood. Pine sapwood quickly
absorbed much water compared to the heartwood of pine. It is very remarkable
that heat-treatment at lower temperatures actually increased the water
absorption of pine sapwood.
