This work aims at one important aspect of hazard analysis compatibility testing of explosives with other materials. We discuss preliminary testing of the Accelerating Rate Calorimeter ARC for use in determining compatibility of a widely used military plastic bonded explosive PBX, PBXN- 106, with a material of known incompatibility. A series of tests was done to determine that the ARC can maintain a typical polyurethaneRDX based PBX in an adiabatic environment precision of repeat runs effect of sample size effect of testing the PBX in contact with an alkaline material. Relative precision for onset of exotherm for six runs was -1.24. Over the mass range tested, 100-400mg, effect of sample size was small 6 change in exotherm onset. Testing the PBX in contact with an alkaline substrate significantly reduced the onset of temperature of exotherm onset.
