Bacterial Filtration Efficiency Tester is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials. The control console adopts microcomputer control system to coordinate and control the work of aerosol generation system, transmission system, negative pressure cabinet and sampling system, and display the working status in real time. The whole measurement work is completed automatically.
Mask Bacterial Filtration Efficiency Tester Standards:
YY 0469-2004 Technical requirements for surgical mask
BS EN 14683-2014 Medical face masks - Requirements and test methods
ASTM F2100-2019 Standard Specification for Performance of Materials Used in Medical Face Masks
ASTM F2101 Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus.
