1. Use a stand to adjust the position of the flammability tester shelf and place the sample (not a prepared sample) so that the burner contacts the sample surface. Place the sample in the test box with the longer frame facing up. Adjust the burner and sample holder, use the indicator that touches the surface of the sample, so that the flame is directed towards the vertical center of the sample, the flame is 19 mm (3/4 inch) away from the bottom of the sample and the burner nozzle is 8mm (8mm) from the sample surface. 5/16 inch).

2. Open the fuel barrel control valve, let it open for about 5 minutes to expel air in the fuel line, turn on the gas and adjust the flame to a length of 16mm (5/8 inch) (The pointof the flame reaches the gas nozzle) mouth).

Without placing the sample, use an instrument with timing accuracy less than 0.05 s and adjust the ignition timing mechanism to 1 ± 0.05 s.

3. Remove an installed sample from the dryer and place it on the firebox shelf. The sample should ignite within 45 seconds after being removed from the dryer. The lift stop line is parallel to and 3/8 inch (9.5 mm) from the bottom surface of the sample holder top plate.

4. Close the instrument door, set the stopwatch to zero, perform the test in a small, freely ventilated room, and test at room temperature.

5. Operate the start lever or button. Turn on the timing mechanism and apply a flame to the sample for 1 second. Timing is automatic, starting when the flame is applied and ending when the stop line is reached.t burned and the hammer is released.

6. Record the time it takes for the flame to propagate for each sample and pay attention to whether the base fabric of the sample with a raised fiber surface is burning, charred, or melted to a point. This can be seen on the reverse side of the sample. The damage is obvious.
