bfe testing machine
It is suitable for measuring the gas exchange pressure difference of masks, and can also be used to measure the gas exchange pressure difference of other textile materials.
Features
1. The pumping gas source is used as the power source of the instrument, which is not limited by the space of the test site;
2. Equipped with precision differential pressure sensor, digitally displays the differential pressure on both sides of the sample;
3. The special sample holder ensures that the sample is held firmly
Why measure the air permeability of mask?
Clothing materials should have certain air permeability, which is conducive to the exchange of air inside and outside the fabric and the metabolism of human skin.Based on this reason,it is necessarily to do air permeability test for fabric.
ASTM F2100 standard specification for performance of materials used in medical face masks
EN 14683 standard that medical face masks in Europe are required to comply with
ASTM F2101 standard test method for evaluating bacterial filtration efficiency (BFE) of medical mask materials using Staphylococcus aureus biological aerosol
YY0469-2011 Technical requirements for surgical mask
YY/T 0969-2013 Single-use medical face mask
Principle of air permeability test:
Under the specified differential pressure condition, the airflow flow through the given area of the sample vertically within a certain time was measured and the permeability was calculated.
Air permeability evaluation:
For thermal underwear products, the higher the permeability, the better the results.For windproof products, the lower the permeability, the better the results.
