The national standard for "Protective masks for daily protection" has been formally implemented since November 1. This is China's first national standard for respirator masks.

The protective effect is the core indicator of the standard. The level of protection effect is set according to the air quality category in the national air quality standard. It is divided into four levels from low to high: D level, C level, B level, and A level.

Grade D is suitable for moderate (PM2.5 concentration ≤ 150 micrograms per cubic meter) and below pollution,

Grade C is suitable for severe (PM2.5 concentration ≤ 250 micrograms per cubic meter) and below pollution,

Grade B is suitable for severe pollution (PM2.5 concentration ≤ micrograms per cubic meter),

Grade A is used when the concentration of PM2.5 reaches 500 micrograms per cubic meter.

According to the national standard, after wearing a mask, the inhaled PM2.5 concentration can be reduced to 75 micrograms per cubic meter, so that the filtered inhalation body's air quality reaches a good level or above, and it is qualified.

The implementation of the "Regulations" will improve the non-compliance of the civilian respirator market.

The “Specifications” has strict regulations on the packaging, labeling, storage, and transportation of masks. It requires that the labels contain “level of product protection effect” and “execution standard number”.

China Industrial Textiles Industry Association took the lead in drafting the "Regulations." Li Guimei, vice president of the association, said in an interview with the reporters from the China-Singapore.com, the standard has 15 indicators, and the products are carried out in three aspects: safety, hygiene and protection. determination. Moreover, with reference to the "Chinese Pharmacopoeia", strict regulations are also made on toxic and hazardous substances.

She said that many well-known brand companies at home and abroad have already carried out the R&D and production of masks according to the "Code" and sent them to third-party authoritative testing organizations for testing. A number of masks that meet the "Regulations" will be listed one after another. The association will also regularly publish a list of companies that meet the standards and cultivate brand pilot companies.

Xiao Bian has something to say: The introduction of the dust mask national standard is really too timely! Later when you go to the store to buy a mask, you may wish to note whether the new product has been marked on the outer packaging of the mask "product protection effect level" and other content, in addition Xiao Bian is also curious about new masks after the listing, now these so-called "old How to deal with masks?
