Test principle For Hot Flaming Oil Flammability Combustion Test Chamber:

Fill 10mL of flammable liquid with the specified performance (average calorific value 38MJ/L, mass per unit volume between: 0.845g/mL～0.865g/mL, flash point: 43.5℃~93.5℃) in the metal ladle, after heating to the distillate fuel oil’s ignition point and burning 1mim, the motor drives the spoon to rotate at a certain height (100mm) and a certain flow rate (1mL/s), and then steadily pour the flammable liquid on the center of the opening of the sample (fire protection enclosure). The fire protection performance of the test product is evaluated by whether the ignition bedding at the specified distance (50mm) and with the specified density (40g/m2) under the test product is ignited.
