TYPE OF SHRINKAGE ^{1, 4}

	INCHES/PERCENT	INCHES/PERCENT	CU.INCHES/PERCENT
GREEN (30%+) 20 10 0	4 3 15/16  /  1.47 3 7/8  /  2.93 3 13/16  /  4.40	6 5 7/8  /  2.56 11/16  /  5.13 5 9/16  /  7.70	60 3 57.54  /  4.10 55.09  /  8.19 52.62  /  12.30

NOTES: 1) SHRINKAGE VALUES FROM TABLE 39 OF THE WOOD HANDBOOK. 2) SINCE LONGITUDINAL SHRINKAGE IS NEGLIGIBLE, VOLUMETRIC SHRINKAGE MAY BE CONSIDERED AS THE COMBINATION OF RADIAL AND TANGENTIAL SHRINKAGES. 3) FOR THIS EXAMPLE, THE 4" x 6" BLOCK WAS 21/2" THICK. 4) MEASUREMENTS FOR SHRINKAGE LOSS ONLY. MFG. LOSSES ARE NOT INCLUDED.

SUMMARY: FROM 20% TO 10%, THE BLOCK WILL SHRINK APPROXIMATELY 1 1/2% RADIALLY, 2 1/2% TANGENTIALLY, AND 4 %   VOLUMETRICALLY.
