- Abstract
- The fire loss probability is composed of all sub-probabilities which are associated with the events and processes leading to the occurrence of the fire loss. The events and processes generally fall into two categories, the selection processes and the physico-chemical processes. The first important event of the physio-chemical processes is ignition after given exposure to heat source. Measurements have been carrid out to provide required data on thermophysical properties, constitutive description of processes, and ignition times. Description of the preignition processes and the prediction of ignition time was formulated and the results compared with measurements. Thermal rediative properties have been measured. Thermal conductance measurments were carried out. Ignition time and ignition frequency measurements under convective heating have been carried out with a microburner ignition source on fire retarded and untreated fabrics. Ignition time measurements on vertical fabric samples under radiative heating were conducted using large samples of fire retarded and untreated fabrics.
