This standard specifies the terms and definitions, requirements, test methods, inspection rules and classification, labeling, packaging, transportation, and storage of daily protective masks. This standard applies to masks made of non-woven fabrics or fabrics, which are used to filter dust, pollen, catkins, bacterial particles, and block pollutants such as exhaled or sprayed droplets from the nasal or oral cavities in daily life. This standard is not applicable to respiratory protective equipment for special industries such as hypoxic environments, underwater operations, escape, firefighting, medical, and industrial use. This standard does not apply to mask products used by infants and young children aged 36 months and below. 1. This section specifies terms and definitions such as particle filtration efficiency, bacterial filtration efficiency, masks for children, and masks for the elderly. Children's masks and elderly masks are the characteristics of this standard, and this section specifies the definitions of these two types of masks. 2. Classification and specifications are pided into flat masks and foldable masks according to their structural types; According to the age of the wearer, masks are pided into adult masks, children's masks, and elderly masks; According to the product filtration level, it is pided into first level, second level, and third level; According to the size of the mask, the specifications are pided into large, medium, and small sizes. This section specifies the specifications of civilian masks, which are mainly classified based on the age group of the wearer, filtering efficiency, specifications, and dimensions. 3. Requirement (1) Basic requirements: Comply with the basic requirements of GB/T32610-20165.1. (2) The appearance, size deviation, and nose clip mask should be clean and in good shape, with no damage or stains on the surface. The nose clip should be made of plastic material. After wearing the mask, it should be able to cover the wearer's mouth, nose, and jaw. It should comply with the designed dimensions, and the maximum deviation should not exceed ± 5%. The folding ratio of flat disposable masks shall not be less than 50%. (3) This section specifies the technical requirements for the length of the nose clip, the breaking strength of the connection between the mask strap and the mask body, ventilation resistance, pH value, formaldehyde content, decomposable carcinogenic aromatic amine dyes, color fastness to friction, color fastness to saliva, and residual amount of ethylene oxide. (4) This section specifies the technical requirements for the total number of coliform bacteria, pathogenic pyogenic bacteria, fungal colonies, and bacterial colonies, among which coliform bacteria and pathogenic pyogenic bacteria shall not be detected. (5) The filtration level is pided into three levels: first, second, and third. The corresponding indicators for each level are: bacterial filtration efficiency is 95%, 95%, and 99%, respectively, and particle filtration efficiency (non oily) is 50%, 85%, and 95%, respectively. 4. Test method appearance: Randomly select 10 samples for testing. Visual inspection shows that the illumination of the fluorescent lamp is not less than 400lx. Structure and size: Randomly select 10 samples for testing. Actual wearing, and measuring the length and width of the mask with a universal or specialized measuring tool, with an accuracy of 0.1cm. Nose clamp: Randomly select 3 samples for testing, check the material of the nose clamp and manually bend it. Take out the nose clamp and measure its length with a universal or specialized measuring tool, with an accuracy of 0.1cm. The bacterial filtration efficiency, the breaking strength of the connection between the mask strap and the mask body, ventilation resistance, pH value, formaldehyde content, decomposable carcinogenic aromatic amine dyes, color fastness to friction, and residual ethylene oxide shall be carried out in accordance with the provisions of GB/T32610-2016. 5. The inspection rules refer to products of the same variety and specification (model) as the inspection batch according to the delivery batch number. Randomly select a corresponding number of samples from each inspection batch according to the testing requirements. The factory inspection items include appearance quality, structural dimensions, nose clips, and mask straps. 6. The minimum packaging of the identification mask should have clear Chinese identification, which should at least include the following information: product name, main raw materials, specifications and dimensions, production date, manufacturer name, production address and date, executive standards, and storage conditions. 7. The packaging and storage of masks should be able to prevent mechanical damage and pre use contamination. The outer packaging must not be damaged during product transportation to prevent rain and sun exposure. Storage shall be carried out according to the storage conditions specified in the label
