Standard: GB 19083-2010 medical protective mask technical requirements

Scope:
It is the special test equipment mainly used for testing medical masks flame retardant properties.

Instrument Description: 
The device is a mask with a head mold at a certain line speed after contact with the flame, then test the burning performance on masks.

Main feature:
1, PLC + touch screen control system; make test more convenient operating, visualization;
2, mask fixture for the metal body head mold, can fully simulate the actual use of the state mask.
3, the burner height can be adjustable
4, automatic timing positioning made by the burner
5, burning time, fire-retardant time are automatically recorded, show the figures.
6, with a flame temperature measurement probe, flame temperature display.
7, automatic control system, automatic ignition;
8, the burner with propane (liquefied gas) and other combustible gas interface.
9, automatic timing, automatic storage of test data; easy access to experimental reports
