Technical Specification of Children Mask

1 Scope

China's national technical specification for children's masks. It specifies the terms and definitions, the classification and specifications, and the technical requirements. Published in May 2020, it addressed a gap that had become urgent: masks were being made and sold for children in enormous numbers, and almost all of them were scaled-down adult products designed against adult requirements. Children are not small adults for this purpose. Their faces are shaped differently, so an adult mask leaks around the edges and its filtration rating means nothing; their breathing resistance tolerance is lower, so a filter that an adult finds acceptable can be genuinely hard work for a child; and they are less able to report discomfort or to adjust a mask correctly. The specification therefore fixes sizes by age, sets a breathing resistance limit lower than the adult one, and covers the hazards specific to children - cords and small parts, and the materials that will be against skin and in the mouth.

This Standard specifies the terms and definitions, classification and specifications, technical requirements, test methods, inspection rules, packaging, marking, safety warnings, storage and transportation of children mask (hereinafter referred to as mask). This Standard is applicable to the masks worn by children 6 years old and above, 14 years old and below to filter particulate matter in the air, blocking microorganisms, pollen, spray, etc. This Standard is not applicable to mask containing electric air supply (exhaust) device.

4 Classification and Specifications

4.1 Classification According to the performance of masks, children masks are divided into child protective mask (F) and child hygiene mask (W).

6 Test Methods

6.1 Appearance inspection 10 masks are taken and visually inspected. The inspection light is subject to normal natural light; if illuminating with a fluorescent lamp, the illuminance is no less than 400lx.

6.2 Color fastness to dry rubbing It shall be implemented according to the provisions of GB/T 29865; cut the sample at the printing or dyeing part of the mask.

6.4 pH value It shall be implemented according to the provisions of GB/T 7573; cut the sample at the contact layer between the mask and the human face.

6.6 Migratable optical brightener It shall be implemented according to FZ/T 01137; cut the sample at the contact layer between the mask and human face.

6.7 Residue of ethylene oxide It shall be implemented according to the provisions of Clause 9 in GB/T 14233.1-2008. Take a parallel sample to test; the sample is cut from the mask body. If the one test result is qualified and the other is unqualified, the average calculation shall not be performed.

6.8 Nose clip length Take 3 samples for testing; measure by general or special measuring tools with accuracy of 0.1cm.

6.11 Inhalation resistance It shall be implemented according to the provisions of
