oven dry weight of the wood Oven dry weight is the quasi-constant weight attained by wood sam- ples dried at 105 co (221 F 0). As pointed out by MacLean (1952) and Stamm (1964), it is advantageous to define moisture content in terms of the oven dry weight of the wood since the oven dry weight is a constant value that may be determined at any time.
