The flame spread tester ISO 5658-2 is developed and produced
according to the ISO 5658-2 standard, and meets the requirements of
IMO FTP Code Resolution A. 653 (16) and ASTM E 1317. The Shenzhen
Demerson Flame Spread Tester ISO 5658-2 is used to measure the
lateral flame spread performance of building products. The flame
spread performance/speed of flame spread can evaluate the fire and
flame retardant performance of materials.
The device radiates heat through a gas radiation plate and uses an
imported heat flux meter to calibrate the radiation heat. The
sample is ignited by a mixed gas burner to test the combustion of
the material under certain radiation heat conditions; Expose the
sample to an area with a clearly calibrated radiation flux, measure
the ignition time, flame spread, and final extinction time. The
test sample is placed in a vertical position, adjacent to the
radiation plate, and exposed to an area with clearly calibrated
radiation flux. The ignition flame approaches the test sample but
does not come into contact with it, and the heated end of the
sample is ignited by the evaporating gas on the surface.
After ignition, record the development of the flame front and the
time it takes for the flame front to burn horizontally on the
surface of the sample to reach various calibration distances.
Further testing the relevant parameters of the material, including
ignition heat, sustained combustion heat, critical flow rate,
average heat of sustained combustion, total heat release, etc.
