ASTM E 648 test method for critical radiant flux of floor-covering
 
Ecosafene Products Technical Service Co.,Ltd have rich experience to provide ASTM E648 fire test to Building Material
 
ASTM E 648 Fire Test to Building Material – Standard
 
ASTM E 648: Standard test method for critical radiant flux of floor-covering systems using a radiant heat energy source.
 
ASTM E 648 Fire Test to Building Material –Test Method
 
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 30°. The radiant panel generates a radiant flux profile along the length of the sample ranging from a maximum of 1.1 W/c m2 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/c m2 ) 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.
