Title: Seasoning and surfacing degrade in kiln-drying ponderosa pine in eastern Washington.

Author: Knauss, A.C.; Clarke, E.H.;

Date: 1961

Source: PNW Old Series Research Note No. 205, p. 1-12

Publication Series: Miscellaneous Publication

Description: This report presents results of a study to determine the degrade (loss in volume and value) of ponderosa pine lumber when cut, kiln-dried, and surfaced in accordance with commercial practice. The study measured (1) loss in volume due to culling and trimming surfaced dry lumber because of sawing, seasoning, and surfacing defects; (2) reduction in grade due to seasoning and surfacing defects; and (3) reduction in grade due to incomplete manufacture or the development of manufacturing defects. Degrade is expressed as a percentage of the rough green lumber volume and also as a loss in value per thousand board feet of lumber.
