The vertical combustion tester is used to measure the flame retardancy, glow propagation and carbonization of fabric, children's wear, foam, paper and other materials.
The purpose of this manual is to provide guidance on setting up and using VFC.
Please refer to the specific test method for sample preparation and test instructions
1. Gas burner
An improved Bunsen burner comes with a non-pyjama test kit.
The burner includes a flame altimeter and a light guide tube.
A tilt burner mounted on the side wall of the test room is provided for children's pyjamas test kits.
2. Gas connection
The gas mixture shall be methane, 99% pure, or specified in the applicable test method.
If side burners are used, the gas supply line is connected directly to the burner inlet via a customer supplied pressure regulator.
If using a Bunsen burner, connect your gas supply to the manual gas control unit and connect the output line of that unit to the burner inlet
3. Position and flame height of Bunsen burner
The burner is placed in such a position that the center of the burner barrel is directly below the center of the sample
On the burner, relative to the indicator tube, there is a metal flame height meter spaced 13 mm (1/2 inch) from the barrel and extending above the burner.
The rod has two 8 mm (5/16 in) tips, marking distances of 19 mm (3/4 in) and 38 mm (1 1/2 in) above the burner top.
Use this gauge when adjusting burner flame height according to applicable test method.
4. Operation of burner
The side burner was used in the test: the empty sample bracket was hung on the support rod of the VFC chamber, and the rear edge of the bracket was clamps on the guide rail of the bracket extending from the rear wall of the chamber.
Place the burner tube directly below the sample center and adjust the stop ring position on the burner (outside the combustion chamber).
Slide the burner out (to the right) and ignite.
The flame height of the burner is adjusted according to the flame altimeter on the inner wall of the combustion chamber.
As mentioned above, remove the empty sample bracket and hang the loaded sample bracket in the cavity.
Close the hatch and conduct the test in accordance with the applicable test method
1. Set the control mode switch to the automatic position.
2. Prepare your test sample and install it in the appropriate bracket in the instrument test room.
3. If possible, place the burner under the sample as per your test method.
4. On the AGC, open the main gas shutoff by lifting the toggle lever upward until the toggle lever points outward from the panel.
Note: Opening this valve allows gas to enter the pilot burner, which must be ignited immediately.
5. Ignite the pilot burner.
6. Close the instrument room door.
7. Press the run time display button on the AGC below to reset the timer.
If the monitor is counting, press the timer Start button to turn it off.
Press the timer reset button to set the display to zero.
8. To start the test, press both the burner start button and the timer start button on the AGC.
Correct operation will be indicated by two switches in the lighting.
If both are not lit, press the timer start switch to turn off the lights, and press the timer Reset button below the run time display.
Simultaneously press both start switches again to start the test.
9. The burner will be extinguished when the timer indicates 15 seconds (HMV) or 12 seconds (VFC).
You can continue counting the elapsed time and stop it as needed by pressing the timer Start button.
You can also stop it using the timer start button, reset it to zero using the timer Reset switch, and restart it by pressing the timer start button to time the burn event.
Press the timer start button again to stop it.
10. Use the run time described above to display or use the handheld event timer provided by the AGC to time the events required.
11. Additional tests can be performed by repeating steps 6-8 above.
12. After you have finished using the AGC, always close the main gas shutoff by pushing the toggle lever completely down (not pointing out of the panel).
Cut off the gas supply to your tank or equipment.
The AGC is electrically closed by moving the control mode switch to the center position.
