TOXICITY
These toxicity tests results compare
to the total sum of toxicity factors (carbon monoxide,
carbon dioxide, and poisonous chemicals) found in the
smoke of burning materials as compared to the smoke from
burning red oak..

FLAME SPREAD
The distance flame spreads
from the igniting flame during a 10-minute fire exposure
under controlled test conditions in a test tunnel.
The results of the test are compared to the flame spread
on asbestos-cement board and the flame spread on an
untreated red oak floor under similar fire exposure.

SMOKE DEVELOPMENT
The amount of smoke
developed during a standardized burning test in a test
tunnel. The results are compared to the smoke developed by
burning an asbestos-cement board and the smoke developed
by burning a red oak floor under similar fire conditions
during a 10-mintue period. The amount of smoke
development is determined by the light absorption percentage
of the smoke using a photoelectric circuit operating
across the test furnace flue pipe.
