Accelerating Rate Calorimetry (ARC®)
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.
