A full-scale fire performance protocol for the
evaluation of school bus seat assemblies was developed.
This protocol is based on the results of full-scale
testing of end-use seat assemblies and computer fire
modeling of the ignition source and burning item(s) in a
single compartment enclosure. Tenability criteria were
applied to the results of the full-scale tests and
computer fire model calculations. The results showed
that temperature is a suitable criterion for this
application. Toxicity of the decomposition products
plays a secondary role in determining occupant
survivability. Occupant tenability limits are exceeded
for ignition sources over 300 kW, independent of the
type of seat assembly. Based on the full-scale test
data, computer simulations were conducted to determine
which tenability criteria were exceeded in the
