AbstractSpecimens of Douglas-fir wood were conditioned at a fixed humidity at 10, 35, and 70°F for periods of 1 to 5 weeks. Each specimen was enclosed in a sealed container along with one or more electrical humidity sensors. The equilibrium relative humidities in the enclosures were measured at the initial temperature and at one or more temperatures in the range between 10 and 70°F. The relative humidities increased with increasing temperature. For specimens conditioned at 10 and 35°F, the values obtained on the first traverse up to 70°F, were not repeated on subsequent traverses, suggesting that the initial increase in temperature causes an irreversible change related to the hysteresis effect. For specimen conditioned at 70°F, the traverses were reversible.
