This machine is designed according to ISO5658-2 standard, while meeting the IMO FTP Code Resolution A. 653 (16) and ASTM E 1317 requirements. Lateral flame propagation properties for the determination of building products, flame propagation performance / flame spread rate of speed can evaluate the fire retardant properties of the material.
The device via a gas radiant plate to heat samples and with heat flow meter to calibration; Test samples were placed in a vertical position, near the radiation plate, exposed in a clear area calibrated radiation flux. Close to the pilot flame test sample, but not in contact with the test sample, the sample was heated end ignited gas on the surface of the evaporator.
After ignition, recording the development of the flame front, and record the flame front in a horizontal direction to reach the surface of the sample, combustion distance of each calibration elapsed time. Further testing materials include light heat, sustained combustion heat, critical flow, the average sustained burn calories, the total heat release and other relevant parameters.
