From your standpoint of filtration efficiency, this typical relies over the class of filter things
And the extent, as well as the detection process, stipulate the filtration efficiency of every product
(See Table 3 ).
Also, GB 2626-2006 has general demands, Visible inspection,
Leakage, respiratory resistance, exhalation valve, dead Area, discipline of perspective, headband, connection
And connecting components, lenses, air tightness, flammability, cleaning and disinfection, production
Technical specifications for example information and facts and packaging that should be provided by the manufacturer.

( 3 ) The latest advancement of GB 2626-2006
It truly is value noting that GB 2626-twenty 06 "Respiratory Defense

The Unexpected emergency Management Division proposed and managed.
At present, the new conventional has been released to The complete Modern society gratis②. In the new regular
Added seven terms including "aerodynamic particle measurement" and revised some
Technological specifications and screening solutions, but with the enumerated classification and marking,
The filtration efficiency has not been modified.

This typical is China's recommended nationwide standard. China Textile Business
The Federation proposed that the National Textile Standardization Technical Committee shall be under the jurisdiction.

This normal is mainly relevant on the air pollution environment in everyday life
The protective mask worn to filter out particles, although not suited to health-related
Use as well as other Unique industries.
Within the point of view of terms and definitions, the particulate subject specified in this conventional is a hoop
Ambient air in an aerodynamic equivalent diameter less two.5 [mu] m of particles
Particulate make any difference, also known as wonderful particulate issue ( PM2.5 ), is the same as other standards in this article
The definition of particulate make a difference varies.
With the point of view of filtration effectiveness, masks is usually divided into: Class I, Class II ,
Class III , the corresponding saline media filtration performance is 99% , ninety five%
And 90% (see Desk four ).
