Vertical Flammability Tester

Vertical Flammability Chamber for measuring the vertical flame spread for children’ sleepwear, fabrics, other textile materials or resilient filling materials used in upholstered furniture. Comprises a draft free stainless steel cabinet with observation window and back wall painted black for easy test viewing. The different specimen holders and associated hardware is dependent on the test standards. Automatic Gas Control System could easily control the combustion process.

Application

This tester is used to detect children's pajamas or decorative fabrics, combustion performance of foam, also it’s suitable for the determination of aviation and transport materials, burning resistance of the tents and protective clothing.

Features

1. Seal 316 stainless steel combustion chamber with observation window for easy test viewing. It is high-heat and high-pressure resistance.

2. Equipped with a standard burn timer to detect the flame spread rate.

3. It’s convenient for operation due to the Burner fixing in the sliding track with Maximum sliding accuracy of 5mm. Adjust the height of the flame with the precision needle valve, and the accuracy is up to 5mm.

4. Stainless steel gas design, and configuration of pressure relief valve, check valve, solenoid valve to get the higher safety.

5. Different test standards are equipped with different sample clamps and metal accessories.

6. Automatic gas control system, including electromagnetic control gas valve, automatic ignition timer and controller.

Test Procedures

a) Set the control mode switch to the automatic position.

b) Prepare the sample and mount it on a suitable sample holder, then place it in the instrument's test chamber.

c) Position the burner below the sample according to the test method requirements.

d) Lift the toggle switch on the AGC upwards until it points towards the device panel, which opens the main gas shut-off valve.

e) Ignite the pilot burner.

f) Close the test chamber door.

g) Press the timer reset button below the time display on the AGC. If the time display is accumulating, press the timer start button to stop the timer. Press the timer reset button until the time display shows 0.

h) Simultaneously press the burner start button and the timer start button to begin the test process. (When both button lights illuminate, it indicates that the operation has been performed correctly. If neither light illuminates, press the timer start button to turn it off, then press the timer reset button below the display.) Press both start buttons simultaneously again to begin the test operation.

i) When the timer displays 15s (HMV) or 12s (VFC), the burner automatically extinguishes. At this point, the time display can be allowed to continue accumulating, or the timer can be stopped by pressing the timer start button as needed. Alternatively, after stopping the timer by pressing the timer start button, it can be reset to 0 using the reset button, and then the start button can be pressed again to restart the timer for the next stage. Press the start button again to stop the timer when the timing is complete.

j) Time the required experimental operations using the time display as described above, or use the portable timer provided with the AGC.

k) Repeat steps 6-8 for additional tests.

l) When the AGC is no longer in use, push the toggle switch downwards (away from the panel) to close the main gas shut-off valve. Close the gas supply valve of the gas source. Move the AGC control mode switch to the center position to turn off the AGC device.
