Brief introduction: MOTIS surface flame propagation test device for BS 6853 series high-speed flame retardant test instrument, applicable to the building materials and high iron flame retardant test standard, conform to the standard BS 476-7, the test method is used to measure the surface of lateral extension and combustion grade is determined based on the speed and the extension length. BS 476-7 is mainly used for determination of metope and ceiling exposed on the surface of the flame. For the test methods, which gradually changes under the radiation heat energy, with small flame samples, and determination of the critical radiation flux. Thermal radiation board size is 850 mm X 850 mm, the test specimen holder adopts water cooling method, porous and thermal radiation flux sensor calibration board, equipped with thermal radiation flux calibration curve. The test equipment for laboratory space demand is higher, the user needs to have more security measures, can assemble the test instrument. Technical parameters: 1, the radiant panel area is 850 mm X 850 mm, strengthen the structural support frame 2, sample holder is perpendicular to the radiant panel, the standard mark, according to calculate the critical heat flux flame propagation distance 3, equipped with water cooling circulation system, can be carried out on the specimen holder water cooling, avoid high temperature cause damage for a long time 4, equipped with small flame ignition device, the use of electric spark ignition 5, radiation board with high temperature testing device, if radiant panel die can be automatically cut off the gas source 6, equipped with water-cooled thermal radiation flux sensor, and the result can be traced back to the United States to NIST 7, equipped with electric control box, adjustable gas and air flow, and show the thermal radiation flux number
