What Are The Implementation Standards For Children's Masks?

Implementation standards for children's masks:

1. Protection performance

Children's protective masks require a particle filtration efficiency of not less than 95% and a protective effect of not less than 90%; children's sanitary masks require a particle filtration efficiency of not less than 90% and a bacterial filtration efficiency of not less than 95%.

2. In terms of comfort performance

Considering the respiratory characteristics of children in the physiological development stage, children's protective masks require that both the expiratory resistance and inspiratory resistance are not higher than 45Pa; children's sanitary masks require that the ventilation resistance is not higher than 30Pa. In terms of the comfort of wearing masks, the standard recommends the use of adjustable mask straps.

3. Safety performance

The mask should be able to cover the mouth, nose, and jaw safely and securely, and there should be no palpable sharp tips and edges, and should not significantly affect the field of vision: The raw materials of the mask should not use recycled materials and materials that can cause adverse reactions, and should not pass through chlorine-containing materials. Bleaching; for masks equipped with breathing valves, the breathing valves should be firm and not deformed, and the inner parts should not fall off; lace-up mask straps should not be used; the nose clip should be folded in half without breaking; the inner material of the mask should not be printed or dyeing.

The standard strictly stipulates the residue of harmful substances, and the formaldehyde content should not be higher than 20mg/kg; the printing pattern on the outer layer of the mask should not fade, and the decomposable carcinogenic aromatic ammonia dye is prohibited; the residual amount of ethylene oxide sterilization should not be higher than 2μg/g; Migration of fluorescent whitening substances shall not be detected.

The standard also stipulates that the microbial indicators should meet the requirements of disposable sanitary products.

4. Wear safety warnings

The recommended national standard of the "Children's Mask Technical Specifications" gives clear wearing safety warnings for the use of children's masks. For example, children should wear masks under the care of adults, and caregivers should observe and educate children to wear masks correctly. Children should not play or do moderate or above-medium-intensity exercise while wearing the mask, and should not disassemble the breathing valve and the internal parts of the breathing valve; if symptoms such as breathing discomfort or skin allergy occur during wearing, the mask should be removed in time, and if necessary, it should be taken off immediately. seek medical attention. Masks should be replaced in time. It is not recommended to reuse masks after washing, and used masks cannot be exchanged. Children with breathing difficulties are not recommended to wear masks. Objects unrelated to the wearing of the mask should be cleaned up during use, etc.
