WWW Computer Program for Testing Cell Data Checks of
Section 9.3 and 12.6 of ASTM D1990

This program assumes that we have one or more sizes of specimens for both Select Structural and Number 2 grades of dimension lumber. We will deal with the Modulus of Rupture (MOR) characteristic.
Please enter your MOR Select Structural Characteristic value in psi

Please enter your MOR No. 2 Characteristic value in psi

Please input the estimated 5th percentile, the 75% upper confidence interval for the 5th percentile and the test span width for each cell that you have data. All values are assumed to be at 15% moisture content. These values are the summary statistics before adjusting to the charcteristic size.
