green weight of the wood 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 ... The density of wood is, of course, not a fixed value but depends upon the moisture content of the wood. Wood density varies greatly from spe-

It is the weight of the wood after it is oven-dried. When wood loses or gains moisture, the change in the dry basis moisture is linearly related to the weight loss or gain. In simpler terms, in dry basis moisture measurement, the weight of the wood is a constant and the increase or decrease in weight is directly related to the amount of water ...

Wagner has compiled species’ average specific gravity (SG) values (wood volume at 12% moisture content (MC) and oven-dry weight) from industry-accepted 3rd-party sources ... (SG) of the wood increases because the formula for the wood density is the weight of the wood sample divided by the volume of the wood sample, or more simply the ratio of ...
