Mask synthetic blood penetration test
For the detection of medical surgical masks and medical protective masks, simulate the rapid blood spray to the outside of the masks, and observe the permeability of blood to the masks.
For the detection of medical protective masks, a total of 10 subjects, 5 men and 5 women, were selected to simulate the use of medical staff. Air leakage performance after matching the mask with the face.
Mask Flame Retardant Test
For the detection of medical protective masks and medical surgical masks, metal head molds and burners are used to simulate the situation where the mask wearer passes in a high-temperature flame to detect the flame retardant effect of the mask.
For the detection of medical protective clothing, the cut protective clothing materials were stretched at the specified speed until breaking through the tensile testing machine to test the strength of the key parts of the protective clothing.
Mask Differential Pressure Test
Aiming at the detection of medical surgical masks and disposable medical masks, to verify whether wearing a mask will make it difficult to breathe, test the ventilation resistance of the mask, and determine the pressure difference between the two sides of the mask.
Mask Bacterial Filtration Efficiency Test
For the testing of medical protective clothing, medical protective masks, and medical surgical masks, to verify the barrier performance of airborne particulates, small non-oily particles with a certain airflow are passed through the medical protective articles to test their filtering efficiency.
