Test principle

1. Use a standard energy heat source to test the mask and observe the burning behavior of the mask. The energy of the fire source is guaranteed by measuring the height and temperature of the flame;

2. The time for masks or other samples to pass through the fire source is stipulated in the standard, and the action time of the fire source is guaranteed by controlling the moving speed of the mask;

3. The burning behavior of the sample is measured by the flame and flameless combustion of the sample;

Test standard: GB19083-2010 technical requirements for medical protective masks; YY0469-2011 medical surgical masks.
