The testing standard for medical protective masks is GB19083-2010 "Technical Requirements for Medical Protective Masks". The main test items are the breaking strength of the mask belt, surface moisture resistance, filtration efficiency, bacterial filtration efficiency, respiratory resistance, flame retardant performance, damp heat test, high and low temperature test, safety performance, total number of bacteria, coliform bacteria, Pseudomonas aeruginosa, golden yellow Staphylococcus, hemolytic streptococcus, total number of fungal colonies, qualitative detection of fungi, bactericidal performance, antibacterial performance of leaching anti-(inhibition) products, antibacterial performance of non-dissolving anti-(inhibition) products, stability, production environment air , The total number of bacteria on the surface of the workbench and the surface of the worker's hands, ethylene oxide disinfection, pressure steam disinfection, etc.
