In the viewpoint of filtration performance, this normal is predicated around the group of filter features
And the level, plus the detection method, stipulate the filtration effectiveness of each and every product
(See Table 3 ).
Also, GB 2626-2006 has general demands, Visible inspection,
Leakage, respiratory resistance, exhalation valve, dead Area, discipline of watch, headband, connection
And connecting elements, lenses, air tightness, flammability, cleaning and disinfection, production
Complex prerequisites like details and packaging that needs to be furnished by the company.

Use together with other Unique industries.
Within the viewpoint of conditions and definitions, the particulate issue laid out in this normal is a hoop
Ambient air in an aerodynamic equivalent diameter less 2.five [mu] m of particles
Particulate matter, also referred to Right as great particulate issue ( PM2.five ), is the same as other expectations in this article
The definition of particulate issue may differ.
In the viewpoint of filtration performance, masks may be divided into: Course I, Course II ,
Course III , the corresponding saline media filtration efficiency is 99% , ninety five%
And ninety% (see Desk 4 ).
