APPLICATION:
ASTM F2100 YY0469 EN 14683 Bacterial Filtration Efficiency Tester or BFE Test
is suitable for metrological verification departments, scientific research institutes, mask manufacturers.
Measure the bacterial filtration efficiency (BFE) of medical face mask materials.
On the basis of complying related standards, its innovative dual air paths for simultaneous contrast sampling enhance the accuracy of sampling
RELATED STANDARD:
STANDARDS | ASTM F2100-01 / F2101-07 | EN 14683 | YY0469-2011 Annex B |
Note: this tester can conform to but not limit to the standards above, for more standards conformance, please contact us.
