Mask is a kind of sanitary product. Generally, it is worn on the mouth and nose to filter the air entering the mouth and nose to achieve It blocks harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper.
Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, and when working in dust and other polluted environments, wearing masks has a very good effect. Masks can be divided into air filter masks and air supply masks.
Medical or not
Masks are divided into medical masks and non-medical masks, (and the latest confirmed) civilian sanitary masks.
At present, my country's mask standards mainly regulate the two major areas of civil protection and medical protection.
Standard for civil protective masks GB/T 32610-2016 "Technical Specifications for Daily Protective Masks", GB 2626-2006 "Respiratory Protective Equipment Self-Priming Filtering Anti-Particulate Respirator", It is mainly suitable for particle protection and played an important role in the prevention and control of this epidemic. However, the barrier masks (mainly flat masks) used in resumption of work and production cannot meet the requirements of the above two standards.
Medical field standards GB 19083-2010 "Technical Requirements for Medical Protective Masks", YY 0469-2011 "Medical Surgical Masks", YY/T 0969-2013 "Disposable Medical Masks", Mainly applicable to medical institutions. However, according to the mask use scene and the user population, there is no suitable standard for sanitary (barrier type) masks used by ordinary people.
In order to better meet the urgent needs of the masses for sanitary masks during the epidemic, it is convenient for enterprises that produce/transform masks to adopt the standard and ensure product quality. To facilitate market supervision, the China Industry Association will research and deploy in the first time, A working group was established to conduct demonstration and research on relevant standards and markets, and urgently proposed to the Standardization Technical Committee of China Textile Industry Federation (referred to as China Textile Federation) Project application for the group standard of "civil sanitary masks". On March 11, the China Industry Association officially released the T/CNITA 09104-2020 "Civilian Sanitary Masks" standard.
