As we all know, aerosol transmission is an important transmission route of the novel coronavirus. Therefore, when choosing a mask, people should pay attention not only to the filtration efficiency of BFE, but also to the filtration performance of PFE, which directly determines the protective performance of the whole mask.
General international standards for masks
1. American Standard
NIOSH 42 -84 quot; NIOSH Guide to the Selection and Use of Masks quot;Particulate Respiratorsquot; is issued by NIOSH (National Institute for Occupational Safety and Health) and is a technical specification of the American Federal Regulations CFR. The relevant standards (or some chapters) and related guidelines (or some chapters) determined by CFR have become the mandatory technical specifications of the United States.
2. Japanese Standard
JIS T 81
51: 2018 quot;Particle ulate respiratorquot;
JIST8151: 2018 is a Japanese national standard issued by the Japanese Industrial Standards Committee (JISC).
3. Australia and New Zealand Standard
AS/NZS 1716-2012 quot;Respiratory Protective Equipmentquot; This standard is Australia and New Zealand The national standard used in New Zealand.
International standard for medical masks
The main function of medical masks is to filter particles in the air and block droplets, blood and body fluids, secretion droplets, etc. > The most important technical indicators for the protective performance of medical masks are the filtration efficiency of particles and bacteria, and the resistance to blood penetration.>
1. European standard
EN 14683-2019 quot;Medical masks - requirements and test methodsquot; This standard is a European standard, formulated and publishedby the European Committee for Standardization CEN, and implemented in 34 EU c countries. The standard itself is not mandatory, but it can be referenced by EU national laws and regulations to internal technical regulations (mandatory standards) of each country.
2. American Standard
ASTM F2100-2019 quot;Standard Specification for Performance of Materials for Medical Masks quot; is the standard of the American Society for Testing and Materials. The association has a history of 120 years. 12,500 from more than 140 countriesMore than 30,000 members and more than 30,000 people have participated in a number of ASTM standards ASTM standards are widely used around the world and have become de facto quot;international standardsquot; in various industries.
