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)
