BENEFITS TO THE WOODWORKING INDUSTRY



The practical objective of all wood seasoning, handling and storing methods should be to minimize moisture content changes in wood during service. The EMC is a moisture content at which the wood is neither gaining nor losing moisture. An EMC between 5% and 8% is recommended. This is the percentage of moisture of its bone-dry weight. Wood is dimensionally stable when the moisture content is above the fiber saturation point. Wood dimensions change as it loses or gains moisture below that point. Since wood shrinks when losing moisture and swells when gaining moisture, this shrinking and swelling may result in warping, checking, splitting, or performance problems. The shrinkage of wood is affected by a number of variables. In general, the greater the density of the wood, the greater the shrinkage
