The ASTM F2101 standard is a standard developed by the American Testing and Materials Authority (ASTM). The full name of this standard is as follows: ASTM F2101-19 Standard test method for evaluating the bacterial filtration efficiency (BFE) of medical facial mask materials using the biological aerosol of Staphylococcus Aureus.
The test method included in the mentioned standard is for the evaluation of medical face mask materials for bacterial filtration efficiency. This test method does not define acceptable bacterial filtration efficiency levels. Therefore, when using this test method, it is necessary to identify the specific situation in which the test was performed.
This test method is specifically designed to measure the bacterial filtration efficiency of medical face masks using a microorganism called Staphylococcus Aureus. Since the most common type of bacteria in hospital infections is Staphylococcus Aureus, this test method uses this microorganism.
The ASTM F2101 standard is designed to create a bacterial aerosol challenge to test samples at a flow rate of 28.3 L / mm. This flow rate is within the limits of the normal breathing range and intermittent impact.
This test method is a quantitative method that allows determination of filtration efficiency for face mask materials for medical use. However, it does not apply to all conditions and forms of biological aerosol exposure. Therefore, the exposure of users should be examined and the suitability of the method should be evaluated. The highest filtration efficiency achieved in this way is 99,9 percent.
Briefly, bacterial filtration efficiency is a measure of the resistance of a material to the penetration of bacteria.
The ASTM F2101 standard evaluates the performance of composite materials used primarily in the production of medical face masks along with their design, compatibility and face sealing properties.
Bacterial filtration efficiency testing services of ASTM F2101 Medical face mask materials are also provided to our businesses within the scope of protective clothing tests.
