Accelerating Rate Calorimeter Testing

ARC data is used for reactive system process characterization, pressure relief system design, defining safe upper and lower limits, self-accelerated decomposition temperature (SADT) analysis, batch and semi-batch reaction process simulation, and physical property definition.

An Accelerating Rate Calorimeter instrument measures a system's adiabatic pressure and temperature response to temperature and time. The ARC® can be used to obtain information about the thermal behavior of reactions, reaction onset temperature, of reaction, heat release rate, pressure rise rate, and amount of condensable vapor and non-condensable gas generated. The ARC® is primarily used for liquid-phase reactive systems. It is also used for safety/performance evaluation of explosives and propellants. In mode, it can be used to evaluate storage conditions.

Building on the calorimetry expertise included in the Differential Scanning Calorimeter, the Accelerated Rate Calorimeter instrument has additional capabilities. These allow performance of experiments requiring low self-heat rate detection with simultaneous pressure measurement, isothermal aging and gas/solid phase reaction analysis. The ARC® has the unique capability of testing reactive chemicals which result in generation, as high as 35,000.

Applicable Standard

ASTM E 1981, Standard Guide for Assessing Thermal Stability of Materials by Methods of Accelerating Rate Calorimetry. This test method covers suggested procedures for the operation of a calorimetric device designed to obtain temperature and pressure data as a function of time for the systems undergoing a physicochemical change under nearly adiabatic conditions. It also outlines the calculation of thermodynamic parameters from the time temperature and pressure data recorded by calorimetric device.
