Abstract

A procedure for the investigation of chemical self-heating processes as possible fire causes is presented. The temperature rise for adiabatic conditions is calculated from reaction enthalpy and specific heat and compared with the relevant ignition temperature of the system. The thermodynamic data can be provided by means of differential scanning calorimetry. Additional information can be obtained from thermogravimetric measurements.
