Name of Test:
Bacterial Filtration Efficiency (BFE) of Medical Face Mask Sample Materials, using a Biologicat Aerosol
of Staphylococcus aureus by ASTM: F 2't01 - 19
Test Organism Used:
Staphylococcus aureus - ATCC 6538
lnoculum Size:
2.00 x loBcFU/ mt
Test Equipment:
Aerosol chrillenge Apparatus with Nebulizer assembly and Cascade impactor
Flow Rate of Cascade lmpactor:
28.3 L / min
Aerosol Size:
3 microns t 0.5
Procedure:
Test sample was clamped between cascade impactor and an aerosol chamber at a distance of 15 cms. Bacterial
aerosol of bacteria - Staphylococcus aureus were generated in the chamber using the nebulizer assembly. Aerossls
of test organisms of size 3 microns were drawn through the test material using a vacuum attached to cascade
impactor. Positive control samples collected aerosol with no test specimen to determine the upstream aerosol counts.
The ratio of upstream to down stream was reported as Percentage Bacterial Filtration efFciency. Following results are
the Average of three readings.
Results:
Sample ldentification Average Bacterial count BFE (Percentage)
