Khoom cov kev taw qhia ntawm cov  Qhov rai Hluav Taws Test Ntaus

The window fire test model simulates a vertical building surface consisting of a main wall and a sub-wall perpendicular to it. The external thermal insulation system is installed on the building surface. The opening of the combustion chamber at the bottom of the test model simulates the window or opening of the floor in the actual building, and the ignited wood. Or the flame of the gas overflows from the window, simulates the attack of the external thermal insulation system when the flame after the bombardment overflows from the window or the hole in the room, checks the damage degree of the external thermal insulation system, and determines the flame propagation property. The test fire source uses about 400 kg of wood, the total heat released in 30 minutes is about 4500 MJ, and the peak heat release rate is about (3 ± 0.5) MW.
