Abstract: As part of the United States Army Toxic and Hazardous Materials Agency (USA THAMA) Quality Assurance program to maintain a set of high-purity (>98 mol %) Standard Analytical Reference Materials (SARMs), the SARMs' purity must be routinely monitored. This report presents data on melting temperature, freezing point depression and heat of fusion as measured by differential scanning calorimetry (DSC) for the seven SARMs suited to DSC methods. These data were then used in the van't Hoff's equation to determine each munition standard's molar purity. The purity of each tested SARM was greater that 98 mol %, which confirmed the integrity of the SARMs.
