3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 bacterial filtration efficiency; BFE
Under specified testing conditions, the mask's ability to filter out bacteria-containing
suspended particles.
NOTE: It is usually expressed as a percentage.
3.2 airflow resistance
The resistance of the mask under the specified area and specified flow rate.
NOTE: It is expressed as pressure difference per unit area.
4 Technical requirements
4.1 Appearance
The mask shall be clean in appearance and in good shape. There shall be no obvious
defects such as damage, stains, sharp protrusions, etc. on the surface.
4.2 Structure and dimensions
After the mask is worn, it shall cover the wearer's mouth, nose and chin. It shall comply
with the marked dimensions and allowable deviations specified by the manufacturer.
The design of the mask shall be able to distinguish its inner and outer sides.
4.3 Nose clip
4.3.1 The mask shall be equipped with a nose clip or a structure that replaces the nose
clip.
4.3.2 The structure of the nose clip or nose clip replacement shall be such that the mask
can be effectively fixed on the nose and fit well to the nose area. The length of the nose
clip shall be no less than 50% of the marked length on the side where the nose clip is
located.
4.4 Mask strap
4.4.1 Earhook mask
The sum of the breaking strengths of each mask strap and the two connection points
between each mask strap and the mask body shall not be less than 15 N.
4.4.2 Strap mask
The breaking strength of each mask strap and the connection between each mask strap
and the mask body shall be no less than 10 N. If there is no fixed connection point
between the mask strap and the mask body, the breaking strength of each mask strap
shall be no less than 10 N.
4.5 Bacterial filtration efficiency (BFE)
The bacterial filtration efficiency of the mask shall be no less than 95%.
4.6 Airflow resistance
The airflow resistance for gas exchange on both sides of the mask shall be less than 40
Pa.
4.7 Microbial indicators
4.7.1 Microbiological limits (products supplied in a non-sterilized manner)
The total number of microorganisms shall be ≤30 CFU/g.
4.7.2 Sterility (products supplied in a sterilized manner)
Masks shall undergo a confirmed sterilization process and the product shall be sterile.
4.8 Residual amount of ethylene oxide (if applicable)
If the mask has been sterilized or disinfected with ethylene oxide, the residual ethylene
oxide content shall not exceed 10 μg/g.
