Author: Date :2021-02-08 Views: order
The fabric vertical flammability tester is suitable for measuring the flame retardant properties of textiles with flame retardant requirements, such as medical protective clothing, clothing fabrics, decorative fabrics, tent fabrics, etc.
 
Technical features of fabric flammability tester:
1. Ignition mode: electronic ignition mechanism;
3. Automatic adjustment of combustion position and time;
4. Ignition time: 0 ~ 99.99 seconds. During the test, the ignition time and smoldering time are automatically recorded and displayed digitally;
5. Flame height: manually adjust by using flame height measuring device;
6. Sample holder: "push-pull" sample holder fixing device;
7. Alarm device: equipped with combustible gas leakage alarm device.
 
Applicable standards:
GB/T5455-1997 "vertical method of textile combustion performance test"
GB5725-2009 safety net
GB/T13489-2008 "determination of burning performance of rubber coated fabrics"
ISO1210-1996 "determination of combustion performance of vertical samples of plastics in contact with small fire sources"
GB8965.1-2009 flame retardant protective clothing for f protection * partial flame retardant clothing
GB23864-2009
GB/T5455-1997

Operating steps:
1. Set the control mode switch to the automatic position;
2. Prepare your test sample and install it in an appropriate bracket in the instrument test room;
3. If possible, place the burner under the sample according to your test method;
4. On the AGC, open the main gas shutoff valve by lifting the toggle lever upward until the toggle lever points outward from the panel;
Note: opening this valve can let gas enter the pilot burner, and the pilot must be ignited immediately;
5. Ignite the pilot burner;
6. Close the vertical flammability tester room door;
7. Press the timer reset button under the running time display on AGC. If the display is counting, press the timer start button to turn it off. Press the timer reset button to make the display zero;
8. To start the test, press the burner start button and timer start button on AGC at the same time. (Correct operation will be indicated by the illumination of two switches. If neither light up, press the timer start switch to extinguish the lamp, and press the timer reset button under the running time display. Press the two start switches again at the same time to start the test;
9. When the timer indicates 15 seconds (HMV) or 12 seconds (VFC), the burner will be extinguished. You can display the elapsed time to continue counting and stop it as needed by pressing the timer start button. You can also stop it with the timer start button, reset it to zero with the timer reset switch, and restart it by pressing the timer start button to time burn events. Press the timer start button again to stop it;
10. use the running time display described above or use the handheld event timer provided by AGC to time the required events;
11. Additional tests can be performed by repeating steps 6-8 above;
12. when you finish using AGC, always close the main gas shutoff valve by pushing the switch lever to the completely downward position (do not point out of the panel). Cut off the gas supply to your fuel tank or equipment. The AGC is turned off electrically by moving the control mode switch to the center position.
