Fire compartment, defined

The first steps of the analysis which were already presented in Kloos et al. (2013a) mainly focused on the performance of the human actions to be applied for fire fighting without running the FDS code. In those situations where human actions had to be considered as dependent on the fire evolution, case-by-case analyses were performed on conditions defined by decisive states of the fire evolution (e.g. smoke in front of the door visible or not, when fire fighters reach the fire compartment). The computational effort of those case-by-case analyses was negligible, since the MCDET tool making use just of the Crew Module without applying a... 

Mentioned above is the requirement for some defined level of fire resistance for fibres and assemblies used in most transport sectors to be determined more often than not by national or international regulations that govern their performance requirements. As mentioned above, cars are included because those textile components in internal passenger compartments only such as seating, carpet, seat belts, and internal side and roof lining fabrics require a defined level of flame resistance. 

The fire is contained within defined compartments by the appropriate fire separating elements (fire resistance),... 

For the purpose of this article, fire tests are associated with the second strategy and defined as experimental methods to characterize the behavior of polymers under more severe thermal exposure conditions that are representative of the growth phase of a compartment fire. These conditions are simulated with a gas-fired or electrical heater or a large gas burner turbulent diffusion flame (flame length of the order of a meter or several feet). The incident heat flux to the specimen is primarily radiative when heaters are used, and mainly convective for flame exposure. Total incident heat flux varies from approximately 1 kW/m to more than 100 kW/m. Note that the maximum radiant heat flux from the sim on earth is approximately 1 kW/m. Polymers that are not treated with fire retardant chemicals typically ignite when exposed to heat fluxes of 10-20 kW/m in the presence of a small pilot flame or hot spark.
