Iii. Instrument Features
The inspection machine uses a Bunsen burner of specified size and a specific gas source (propane). The test sample in a vertical position is ignited at a certain flame height and a certain burning Angle at regular intervals. The flammability and fire hazard of the test sample are evaluated based on the duration of ignition, burning and burning length of the test sample. The operation is simple and the measured values are accurate.
