Fourth, random accessories
1. 1 set of weights to measure damage length 5 pieces.
2. 1 sample holder.3rd flame nozzle with one burner.
4. A power cord.
5. Preparation before the test
1. Prepare the pattern for the test.
2. Prepare the gas source for the test.
3. Connect the air source to the instrument to ensure no air is leaking from the connector.
4. Connect the lab power supply and the instrument with the included power cord.
5. Place the fabric pattern in the pattern frame clip and the bottom of the pattern should be flush with the bottom of the pattern clip.
6Operation Steps
1. Close the front door of the combustion test chamber, turn on the instrument (press the 1 end of the power button), and the power indicator lights up.
2. Observe the position of the detonator, if it is not in the home position, click the back button to return to the home position.
3. Set the time. The device defaults to 12 seconds (specified by the national standard). If you don't need to change the time, you can skip this step. To set the ignition time: Press Esettings. first and the cursor will flash if you need to change the position. can increase time, can decrease time.
4. Open the gas source valve (gas flow rate should not be too large).
5 . After all the settings are completed, prepare for the test, press the ignition button, the solenoid valve will open, and the pulse igniter will automatically ignite after 2-3 seconds. If it is difficult to ignite, you can press the Adjust flame setting until it ignites (clockwise should decrease, counterclockwise should increase). Press the ignition button and the ignition will continue automatically for 10 seconds. If the burner fails to ignite once, you can press the ignition button again to start the firer to reignite.
Note: If If you hear the alarm tone, this indicates an air leak in the instrument's internal piping. Please turn off the power immediately, check the air circuit and run the test again after eliminating the possibility of air leakage.
6. Open the front door of the combustion test chamber, place the flame height ruler (40mm high) directly over the flame by hand, and adjust the flame adjustment knob, adjust the flame height to 40mm ± 2mm after the flame is stable , remove the flame height gauge, hang the sample vertically in the middle of the box together with the sample holder, and close the door.
7. Click the Start button and the burner will move to the sample hanging position (at this point it should be within 1 minute after the sample is taken out of the sealed container), after the set time has elapsed, the burner will automatically stop and return, and at the same time the “afterburning time” will start. Start timing.
8. Observe the state of the sample in the test chamber, ;At the end of the glow press the Afterburn Stop button Press; if there is no smolder, press the smolder stop button directly, the smolder time is automatically counted, and when the smolder is finished, press smolder stop, record the afterflame time and smolder time, and record the phenomena occurring during the test. /p
9. Open the front door of the combustion test chamber and take out the sample holder, unload the sample, and then select the specified weight according to the weight per unit area of the fabric to test the to measure damaged length (see the standard for details).
10. Click the Clear button and the device will return to the initial state, open the door of the test chamber, remove small parts and debris from the chamber, open the ventilation equipment and release the smoke and gas from the test chamber. After exhausting, close the exhaust equipment and the test is over.
11. If you need to continue the experiment, repeat steps 5-10 are enough. WeIf not required, turn off the gas source, turn off the power (press the power switch to the 0 position), and then unplug the power cord to end the test.
Seven, Note
1. Smoking is strictly prohibited at the place where the instruments are stored and gas cylinders, put an end to the fire and extinguish the smoldering samples immediately after the test. Fire extinguishing equipment such as carbon dioxide should be provided.
2 , carefully check the gas before starting the machine pipeline, gas leakage is strictly prohibited. When the gas leaks, it is strictly forbidden to do the test fstop and power should be cut off immediately to check the leak.
3. Operators should wear protective clothing and gloves to prevent hands from being pricked or scalded.
4. This test is best performed in a fume hood to remove the noxious gas immediately after the test and replace it with fresh air.
5. If you encounter any problems during the test, please turn off the device first and turn it on again after troubleshooting.
6. After the test, the gas source should be off firstswitched. After the gas in the tube burns out, turn off the power.
7. Before starting the test, make sure the igniter is ignition position, if not, click the back button to return the igniter.
8. The instrument must be good ground wire!
