Accelerating Rate Calorimetry
The method describing IsothermalTests at controlled and constant temperature are called isothermal.isothermal and AdiabaticAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios
and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.adiabatic test procedures used to detect Thermally induced reactionA thermally induced reaction is a decomposition reaction exclusively started through heat treatment. thermally induced ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermic Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition reactions.

Accelerating Rate Calorimeters (Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®) help industry operate safely and profitably.
As highly versatile, miniature chemical reactors, they measure thermal and pressure properties of ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermic chemical reactions. The resulting information helps engineers and scientists identify potential hazards and address key elements of process safety design including emergency relief systems, effluent handling, process optimization, and Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability.
