A simulation model is implemented in order to predict
the performance of materials in the ISO 9705 Room-Corner
Test. These materials were tested by the L S Fire
Laboratories of Italy, and the data they provided is
analyzed in this report. A method was established to
define material properties including the heat of
combustion, heat of gasification, thermal inertia,
ignition temperature and the total energy per unit area.
These methods were developed from refinements in the
theoretical model of ignition and in resolving time
dependent effects in the Cone Calorimeter. The materials
examined consist of some of the worst behaving since
they melt, drip, expand and de-laminate from the wall
and ceiling configuration of the room-corner test.
Corrections have been included in the simulation
modeling to account for these effects. The correction
involves reducing the total energy per unit area content
of the material to accordingly reduce its contribution
as a wall-ceiling oriented element. An empirical
correlation based on a linearized upward flame spread
model is shown to provide very good correlation to the
flashover time in the full-scale ISO test.
