Name：LFY-650 Comprehensive protective mask flame retardant performance tester
Details
The main purposeIt is mainly used to test the combustion performance of the comprehensive protective mask (full-face mask) after six different parts of the flame are ignited at the same time for a certain period of time. It is a special test instrument for the flame-retardant performance of the comprehensive protective mask.
Instrument characteristics
1. The full face mask fixture is a metal human head mold, which can fully simulate the actual use state of the full face mask.
2. The burner is equipped with propane gas interface.
3. The burner flame height is adjustable.

6. Equipped with flame temperature measurement probe and flame temperature display.
Technical index
1. The total air flow of six igniters is (21±0.5) L/min
2. The flame height can be adjusted
3. The diameter of the flame temperature measuring probe is 1.5mm
4. The flame temperature at the height of 250mm from the top of the burner is (950±50)℃
5. The distance between the top of the burner and the six ignition points of the mask is 250mm
6. The wall thickness of the metal head mold is 2～3mm, flame-resistant and burn-resistant
7. Ignition time timer: 0-99.99 seconds, accuracy: ±0.01 seconds
8. Power supply: AC220V, 50Hz, 50W
