Figure 24-28. — (Top) Density profile in 1/2-inch-thick southern hardwood fjokeboard of 

 three densities, as described in caption of figure 24-27, from mid-thickness centerline 

 to face. Densities based on ovendry weight and volume at 5 percent moisture content. 

 (Bottom) Profile expressed as density ratio, i.e., the layer density divided by average 

 panel density. (Drawings from Study File FS-SO-3201 -1 5, U.S. Department of Agricul-
