Four Tests Masks Manufacturers Must Know
Mask Synthetic blood penetration test:The mask material was tested with synthetic blood under continuous applied pressure, and the penetration of synthetic blood on the material was visually checked.It is useful in establishing claims for penetration resistance performance of medical face masks and ranking their performance.
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.
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.
