Determining Loss of Wood Substance in Outside Chip Storage: A Comparison of Two Methods

摘要

Two methods, determining loss in weight and determining loss in specific gravity, were used to evaluate loss in wood substance during outside chip storage. The same wood samples were evaluated by both methods, and results compared. The two methods gave almost equivalent results after 6 months storage in a tower that simulated a chip pile and in an experimental chip pile. After storage, change in green volume was negligible up to 6.5 percent weight loss, and verified the validity of the specific gravity method to evaluate losses in wood substance. (Author)
