EN 14683 Medical face masks Bacterial filtration efficiency
The European Standard EN 14683:2019 specifies the requirements and test methods for medical protective face masks, including their performance in preventing the spread of infectious agents. One crucial parameter is bacterial filtration efficiency (BFE), which measures how effectively a mask blocks bacteria from passing through its fabric. This service ensures compliance with BFE testing standards to guarantee patient safety during surgical procedures or other high-risk environments.
Bacterial filtration efficiency tests are conducted in accordance with the specified conditions detailed within EN 14683. Specimens of medical face masks are exposed to a bacterial aerosol, typically consisting of Staphylococcus aureus (ATCC 25923) or Pseudomonas aeruginosa (ATCC 27853), at defined concentrations and flow rates. The mask is placed in a specialized testing chamber where the aerosol passes through it, and the amount of bacteria that penetrates the mask is measured.
The test apparatus includes an aerosol generator, a sampling device, and a differential pressure sensor to monitor airflow. Specimens are clamped between two parts of the testing chamber, ensuring they represent real-world usage conditions. The flow rate through the specimen should be controlled within ±20% of the specified value.
Following the test, the bacterial concentration downstream from the mask is compared with that upstream. This allows for calculation of the percentage reduction in bacterial aerosol penetration across the mask, which defines its BFE. Masks must achieve a minimum BFE of 95%. Compliance ensures that healthcare professionals and patients are adequately protected against airborne bacteria.
