A. Overview
Theface mask inflaming retarding tester is used to test the flame retardance ofmedical masks. The tester uses propane as the combustion source. Face masksample is placed on a metal-made human head. The height and rotation speed ofthe head model is adjustable. Flame temperature up to 800℃.
B. Applicable Standards:
GB/T19083-2010:Technical requirements for protective face mask for medical use
YY0469-2011:Surgical mask
GB2626-2019: Respiratory protection—Non-powered air-purifying particle respirator
C. Features:
1. Themask fixture is a human head model, which can fully simulate the actualcondition of usage.
2. Thecombustor is equipped with a combustible gas interface such as propane(liquefied gas).
3. Theheight of the combustor is adjustable.
4. Thecombustor performs positioning and timing automatically.
5. Theburning time and inflaming retardant time are automatically recorded anddisplayed digitally.
6. Equippedwith flame temperature measuring probe and temperature gauge.
D. Technical Parameters
1. Thelinear velocity of the head model nose tip is (60±5)mm/s
2. Flameheight can be adjusted (default: 40±4mm)
3. Thediameter of the flame temperature measuring probe is 1.5mm
4. Theflame temperature is (800±50) ℃ at aheight of (20±2) mm from the top of the combustor
5. Thedistance between the top of the combustor and bottom of the mask is (20±2) mm
6. Thecombustor height adjustment range is 30mm
7. Thethickness of the head model is 2~3mm, which is resistant to flame andcombustion
