BEIJING -- Chinese regulators have taken new measures to strengthen quality control over exports of medical supplies and further regulate outbound procedures to better aid the global battle against the novel coronavirus disease (COVID-19).
China will step up supervision on exports of non-surgical face masks, which are required to meet the quality standards of either China or respective export destinations starting from Sunday, according to a joint release from the Ministry of Commerce (MOC), the General Administration of Customs and the State Administration For Market Regulation.
Exporters of non-surgical face masks should file the joint declaration of the exporter and importer when going through customs clearance to make sure they are up to standards and will not be used for surgical purposes, according to the new policy.
kn95 is a mask certified by China's GB2626-2006 respiratory protection user self-priming filter anti-particle respirator standard. It is equivalent to the protection level of n95, but only follows the test standards of different countries. Let's take a look at the use of kn95 masks.
The filtration efficiency of kn95 grade masks for particles with an aerodynamic diameter ≥0.3µm is above 95%. The aerodynamic diameter of airborne bacteria and fungal spores mainly varies between 0.7-10µm, which is also within its protection range.
Therefore, this type of mask can be used for respiratory protection of certain particulate matter, such as grinding, cleaning and processing of dust generated by minerals, flour and certain other materials. Particulate matter of harmful volatile gas.
Can effectively filter and purify the inhaled abnormal odors (except toxic gases), help reduce the exposure level of certain inhalable microbial particulates (such as mold, anthrax, tuberculosis, etc.), but it cannot eliminate contact infection, illness or death risks of.
