ISO 9239-1 ASTM E648 Fire Tester Critical Radiant Flux with a
Radiant Heat Energy Source
Description:
FLOORING RADIANT PANEL TEST (CRITICAL RADIANT FLUX), ASTM E 648,
NFPA 253, FED. STD. NO. 372, NBSIR 75-950: The Floor Radiant Panel
apparatus involves a horizontally mounted floor covering test
sample which receives radiant energy from a gas-air fueled radiant
panel mounted above one end of the sample and inclined at an angle
of 30o. The radiant panel generates a radiant flux profile along
the length of the sample ranging from a maximum of 1.1 W/cm2
immediately under the panel to approximately 0.1 W/cm2 at the end
of the test sample. A gas fired pilot burner is used to initiate
the ignition in the sample. The distance the flooring system burns
to extinguishment is converted to watts per square centimeter
(W/cm2) and is reported as critical radiant flux (CRF). This is the
minimum radiant energy a fire needs to sustain flame propagation in
the flooring system. In this test, a higher number indicates a more
flame-resistant system; i.e., 0.45 W/cm2 is better than 0.22 W/
cm2.
