KN95 Face Mask

KN95 mask is a standard Chinese masks, is our country for a particle filtration efficiency of mask. KN95 masks masks and N95 respirator from particle filtration efficiency for, in fact is the same. KN95 mask is a standard Chinese masks, is derived from the Chinese national standard GB 2626-2019 the respiratory protective equipment self-priming prevent particulate respirator filter type ". This standard is KN95 Face Mask mandatory national standards in China, put forward by state administration of work safety (saws), by the national individual protective equipment standardization technical committee (SAC/TC 112) under centralized.

From the scope of view, this standard applies to ordinary protection self-priming filter type respiratory protective equipment of all kinds of particles, the typical such as masks and other special environment (such as oxygen environment, underwater operation, etc.) shall not apply to the particulate matter definition, this standard defines the particles of various forms, including dust, smoke, fog, and microorganisms, etc., but not for the size of the particles. From the filter element level, can be divided into oily and filter non oily particles KN type and non oily particles of KP, and as a mark, and the explanation of CFR 42-84-1995. Similar guidelines of N and R/P.

In addition, there are general requirements Full Body Disposable Coverall of GB 2626-2006, appearance inspection, leak, respiratory resistance, exhalation valve, dead space and field of vision, headband, connection and connecting parts, lens, air tightness, flammability, cleaning and disinfection, manufacturers should provide information, packing and other technical requirements. It is worth noting that the GB 2626-2006 "respiratory protective equipment self-priming prevent particulate respirator filter type" will become invalid, instead of the new standard GB 2626-2019 "prevent particulate respirators self-priming filter type respirator", is by the state administration of market supervision and management on December 31, 2019 by the law of the People's Republic of China in 2019, the 17th national standard announcement to the whole society, and will take effect on July 1, 2020, the new standard by the emergency department and focal points are put forward.

At present, the new standard of text has been published and as a mandatory standard free open to the whole society. New standard added seven terms, including the aerodynamic diameter changes some of the technical requirements Medical Disposable Coverall and testing methods, but for this article enumerated the classification and marking of, didn't modify the N95 filtering efficiency is the standard type N95 respirator is NIOSH (National Institute for Occupational Safety and Health in the United States, the National Institute for Occupational Safety and Health) certification of one of the nine particulate respirators. N95 is not a specific product name, as long as the N95 standards, and through NIOSH review products can be called a type N95 respirator, aerodynamic diameter (including 0.075 m can be + / - 0.020 (including m particle filtration efficiency above 95%.
