As we all know, an important transmission route of the new coronavirus is aerosol transmission. Therefore, when people choose masks, they should not only pay attention to the filtration efficiency of BFE, but also the filtration performance of PFE, which directly determines the protective performance of the entire mask.
General international standards for masks
1.American Standard
NIOSH 42 -84 "NIOSH Guide to the Selection and Use of Particulate Respirators" Issued by NIOSH (National Institute of Occupational Safety and Health), it is the technical regulations of the CFR of the United States Federal Regulations. The relevant standards (or parts of the chapters) and relevant guidelines (or parts of the chapters) specified in the CFR become the mandatory technical specifications of the United States.
2.Japanese standard
JIS T 8151: 2018 "Particulate respirators"
JIST8151: 2018 is the Japanese national standard, issued by the Japanese Industrial Standards Committee (JISC).
3.Australia and New Zealand standards
AS/NZS 1716-2012 《Respiratory protective devices》 This standard is a national standard used by Australia and New Zealand.
International standards for medical masks
The main function of medical masks is to filter particles in the air, blocking droplets, blood, body fluids, secretion droplets, etc. The key technical indicators that play a protective performance in medical masks are the filtration efficiency of particulates and bacteria, and blood penetration resistance.
1.European standards
EN 14683-2019 "Medical face masks-Requirements and test methods" This standard is a European standard, formulated and issued by the European Committee for Standardization CEN, and implemented in 34 EU countries. The standard itself is not mandatory, but it may be subject to the laws of EU countries The citation of regulations becomes the technical regulations (mandatory standards) within each country.
2.American Standard
ASTM F2100-2019 "Standard Specification for Performance of Materials Used in Medical Face Masks" is a standard of the American Society for Testing and Materials. The association has a history of 120 years. More than 12,500 members from more than 140 countries and more than 30,000 participated A number of ASTM standards, ASTM standards are widely used all over the world, becoming the de facto "international standards" in various industries.
