Flame Height Adjusted Surgical Mask Tester YY0469-2011 High Accuracy

 

The mask flame retardant tester is used to test the combustion performance of medical masks after contacting the flame at a certain linear velocity. It is a special test instrument for the flame retardance of medical masks. It is a test item to detect the flame retardancy of protective masks. Combustion power source. The system is equipped with a metal head mold. The mask is brought into the metal head mold. The metal head mold is equipped with a rotation speed that can be adjusted, a certain moving speed and height can be set, and it can be burned at a high temperature of 800 ° C. Flame retardant properties.

 

 

Mask flame retardant tester meets standardsGB 19083-2010, YY 0469-2011, GB 2626-2019.
