Accelerating rate calorimeter - KELVN international safety services pvt ltd.

Accelerating rate calorimetry (ARC) is a common tool used in thermal stability evaluation of hazardous materials to provide self-heat rate and pressure data that are used to model the kinetics of a reaction and even calculate relief vent sizing.

ARC is a benchmark instrument, uses a measurement technique designed to provide temperature-time

and pressure-time data of chemical decompositions or reactions under adiabatic conditions.

ARC can detect low temperatures of 0.01°C due to this accurate onset of exothermic event can be

realized.

ARC has important parameter which is phi-correction of the heat generated during reaction due to part

of heat generated is absorbed by test cell where phi-corrected data is important.

ARC provides most important and widely used industrial safety parameter called Time-to-maximum rate

under adiabatic conditions (TMRad for 24hours).
