The Shrinking and Swelling of W ood and Its Effect on ...
www.extension.purdue.eduWith time, the moisture content of wood will always come into equilibrium with the relative humidity of the air surrounding it. This moisture content is referred to as the equilibrium moisture content (emc) of the wood. It follows that for each level of relative humidity of the air, there is a corresponding equilibrium moisture content of the wood.

The labile deuterons (and protons) of water are available to exchange with labile protons in the chemist's sample and can result in inaccurate integration ratios.
