An Apparatus for STudying the Fire Resistance of Hydraulic Fluids at Elevated Pressures


An apparatus has been developed to study the spontaneous ignition phenomenon of hydraulic-type fluids at elevated pressures. Investigations are conducted at selected conditions of temperature, pressure, and reactant concentration. The level of fire resistance is measured in terms of a minimum reaction temperature and a minimum spontaneous ignition temperature for each set of reaction-controlling parameters. In addition, the closed system affords a measure of the energy release associated with the combustion in terms of temperature and pressure rise. Modifications of the basic apparatus can be made to study the influence of scaling and surface effects.
