01/02/1995  According to a study by the American Foundrymen's Society Green Sand Test Committee (4-D), failure to lubricate a specimen tube could result in a 3 psi reduction in green compression strength because the density of the sample is changed. If lab equipment isn't calibrated, a slow deterioration in properties could result.
