The surface flame propagation test equipment is the BS 6853 series of high-speed rail flame retardant test equipment, which is suitable for the British building materials and high-speed rail flame retardant test standards. It can also comply with standard BS 476-7.
The test method is used to determine the lateral extension of the sample surface and determine the combustion grade based on speed and the extension length. BS 476-7 is mainly used to determine the flame extension on exposed surfaces of walls and suspended ceilings.
The test method is to ignite the sample with a small flame by receiving the gradual change of radiant heat energy, and then determine the critical radiant flux. The size of the heat radiation plate is 850mm X 850mm. The test sample holder adopts water cooling method, equipped with a porous calibration plate and a heat radiation flux sensor, which can calibrate the heat radiation flux curve. The test instrument has high requirements on the laboratory site, and users need more safety measures before they can assemble the test.
