(1) Filtration efficiency: Under the condition of air flow rate (30 ± 2) L/min, the filtration efficiency of sodium chloride aerosol with a median diameter of (0.24 ± 0.06) μ m in aerodynamics is not less than 30%;
(2) Bacterial filtration efficiency: Under specified conditions, the filtration efficiency for Staphylococcus aureus ATCC6538 is not less than 95%;
(3) Pressure difference: Under specified conditions, the pressure difference for gas exchange between the two sides of the mask should not exceed 49Pa;
(4) Synthetic blood penetration: After 2ml of synthetic blood is sprayed towards the outer side of the mask at a pressure of 16.0kPa (120mmHg), there should be no penetration on the inner side of the mask.
