Ron, Just so I confirm I understand the calculation, may I restate your calculation: Ron wrote, "The dimensional change rate is calculated from the same data as a 0.001" per 1" per MC%" Restated as: I'll say my hypothetical sample test piece measured the following pre and post oven drying 6" across the grain pre oven drying 5" across the grain post oven drying change in dimension, pre (minus) post oven drying =1" Emc before oven drying 5% 1"(dim change after oven drying)/6"(original cross grain dim) =.166" dim change per 1 inch of pre oven stock If it shrinks .166" with an emc change of 5%, shrinkage with an emc change of 1% is .166/5= .03" per 1% of emc change.
