A. Overview

The face mask inflaming retarding tester is used to test the flame retardance of medical masks. The tester uses propane as the combustion source. Face mask sample is placed on a metal-made human head. The height and rotation speed of the 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

GB 2626-2019: Respiratory protection—Non-powered air-purifying particle respirator

C. Features:

1.      The mask fixture is a human head model, which can fully simulate the actual condition of usage.

2.      The combustor is equipped with a combustible gas interface such as propane (liquefied gas).

3.      The height of the combustor is adjustable.

4.      The combustor performs positioning and timing automatically.

5.      The burning time and inflaming retardant time are automatically recorded and displayed digitally.

6.      Equipped with flame temperature measuring probe and temperature gauge.

D. Technical Parameters

1.     The linear velocity of the head model nose tip is (60±5)mm/s

2.     Flame height can be adjusted (default: 40±4mm)

3.     The diameter of the flame temperature measuring probe is 1.5mm

4.     The flame temperature is (800±50) ℃ at a height of (20±2) mm from the top of the combustor

5.     The distance between the top of the combustor and bottom of the mask is (20±2) mm

6.     The combustor height adjustment range is 30mm

7.     The thickness of the head model is 2~3mm, which is resistant to flame and combustion
