Abstract

Equilibrium moisture content of solid wood and reconstituted wood is analyzed to determine the level of relative humidity and temperature control necessary to maintain EMC within desired limits during conditioning. The necessary degree of control is found to be highly dependent on relative humidity and temperature.
