The required tests for pre-qualification are: 1) ,filtration efficiency,, 2) inhalation resistance, 3) exhalation resistance, and 4) exhalation valve leak (when applicable). There are additional respiratory ,protective standards, required in other countries, including CSA Z94.4-01 in Canada, HSE 282/28 in the United Kingdom, AS/NZS 1715:1994 in Australia and EN529:2005 in Europe.

This ,standard, specifies the minimum requirements for new single- and multiple-use emergency ,protective clothing,, including garments, gloves, footwear, and face ,protection, devices. This ,protective clothing, is used by emergency medical responders providing services prior to arrival at medical care facilities and by first receivers at medical care facilities during emergency medical operations.

The barrier performance classes of medical face mask materials are based on bacterial ,filtration efficiency,, differential pressure, sub-micron particulate ,filtration efficiency,, resistance to penetration by synthetic blood, and flammability. Users should refer to the ASTM F2100-19 document for testing procedures and other specific requirements.

or even 99% ,protection, is required to prevent the spread of transmission diseases. The high degree of ,filtration efficiency, is attained with a very fine ,filter, layer of ,textile, fibres covered on both sides with conventional non-woven bonded ,fabrics,. The thickness of fibre is from <1 to 10 µm. Polypropylene, polystryrene, polycarbonate,

For example, the ,filtration efficiency, (i.e. inverse of the penetration) of ,fabric, materials was in the range of 3–33% (penetration range 67–97%) for 1000 nm particles at 5.5 cm s −1 face velocity that is comparable to the ,filtration efficiency, (27–73%) of single-layer ,fabric, materials against B. globigii particles (2000 nm) at a breathing flow rate of 10 l min −1 (Guyton et al., 1959).
