Cellular Plastic Materials Flammability Test Chamber Horizontal Burning PLC Control ISO9772

1) Press  Start button for 3-5s or button 1 on the remote control to light up the flame. Adjust the flame height according to the standard requirements.

2) Close the window door and re-posit the burner under the specimen according to standard requirements, press Start Timing button or button 3 on the remote control to start the flame application time timing. The flame application is 60s, and after reaches 60s the flame is extinguished, and the Elapsed time t_e starts timing.

3) Press te Pause button or button 3 on the remote control to stop the Elapsed time t_e timing when the specimen flam reaches the 60mm gauge mark.

4) Press te/tb Pause button or button 5 on the remote control to stop the Elapsed time t_e and Burning time t_b timing when the specimen ceases to burn or glow before reaching 60mm gauge mark.

5) Press [t_b Pause / Start] to be tb Start or button 4 on the remote control to start the Burning time t_b timing when the specimen flam reaches the 25mm gauge mark, whether the burning is on the bottom, top or edge of the specimen.

6) Press [t_b Pause / Start] to be tb Pause button or button 4 on the remote control to stop the Burning time t_b timing when the flam or glowing combustion front reaches the 125mm gauge mark, or when the specimen ceases to burn or glow before reaching 125mm gauge mark.

7) Operator should calculate out the distance burnt (L_d): this is the distance between the 25mm gauge mark and the point where the flame or glowing combustion front stopped, expressed in millimetres. If the flame front went out before the 25mm mark, record that L_d =0.

8) After each test, open the exhaust fan in time and then clean the support gauze, burner, wing top and chamber; if operator needs to process the second test, press [Count Cleared] to clear all the timers firstly, allow the support gauze to cool to room temperature, check the flame at least once every five tests.
