LFY-650 Flame Retardant Performance Testing Instrument for Comprehensive Protection Masks

Main purpose 
It is mainly used to test the combustion performance of full-face masks (full-face respirators) after being exposed to six different flame sources simultaneously for a certain period of time. It is a dedicated testing instrument for the flame resistance performance of full-face masks. 
Instrument characteristics 
1. The full-face mask fixture is a metal human head model that can fully simulate the actual usage state of the full-face mask. 
2. The burner is equipped with a propane gas interface. 
3. The flame height of the burner can be adjusted. 
4. The head mold fixture can be adjusted freely in both vertical and horizontal directions. 
5. The ignition time is automatically recorded and displayed numerically. 
6. Equipped with a flame temperature measurement probe and a flame temperature display. 
Technical indicators

1. The total gas supply flow rate for the six igniters is (21 ± 0.5) L/min. 
2. The height of the flame can be adjusted. 
3. The diameter of the flame temperature measurement probe is 1.5mm. 
4. The temperature of the flame is (950 ± 50) °C at a height of 250mm from the top of the burner. 
5. The distance from the top of the burner to each of the six ignition points on the mask is 250mm. 
6. The wall thickness of the metal head mold is 2 to 3 mm, and it is resistant to flames and combustion. 
7. Ignition time timer: 0 to 99.99 seconds, accuracy: ±0.01 seconds 
8. Working power supply: AC 220V, 50Hz, 50W
