To test the flammability of materials, a sample is
placed on a substrate and exposed to a uniform heat
flux. Measurements include sample mass and upper and
lower surface temperatures as functions of time.
Several analytical models have been developed in an
attempt to fully understand the relationship between
properties of the tested materials and test results.
Most of these models have assumed a semi-infinite
sample, although the finite thickness of the sample is
known to have a significant effect on pyrolysis
behavior. An analytical solution that includes finite
sample thickness and the material properties of the base
is introduced in this abstract.
