STATISTICAL EVALUATION OF CALORIMETRIC MEASUREMENTS ON HEAT-SOURCE MATERIALS

Abstract

A statistical study was made to determine the precision of calorimetric determinations made on the Parr Model 1411 calorimeter. In addition, the calorific values for continuous-production heat-source material and for an experimentally prepared homogeneous material were determined, and the variability of measurements are compared. It was found that operator-skill and techniques employed can result in a significant increase in the precision of measurements obtained. Procedures intended to increase precision are given. When the determinations with the Parr Model 1411 calorimeter are carefully made, the variance in calorific values due to the calorimetry is small compared to the variance of the determinations made on samples from a typical run of continuous production heat-source material.
