The testing standards for children's masks have been moving the hearts of all parties from scratch. As a testing center for protective products, the Hundred Inspection Testing has always been paying attention to the issuance of standards related to children's mask testing. GB/T38880-2020 was first released before the large-scale start of school nationwide on May 6th and officially implemented on the same day, indicating the importance that the country attaches to the standardized management of children's masks

In terms of mask protection performance:

Children's protective masks require a particle filtration efficiency of no less than 95% The protective effect shall not be less than 90% Children's hygiene masks require a particle filtration efficiency of no less than 90% The bacterial filtration efficiency shall not be less than 95%

In terms of comfort performance:

Children's protective masks require that the exhalation resistance and inhalation resistance should not exceed 45Pa Children's hygiene masks require a ventilation resistance of no more than 30Pa

In terms of safety performance:

The mask should be able to safely and firmly cover the mouth, nose, and jaw, without any accessible sharp ends or edges, and should not significantly affect the field of vision;

The raw materials of masks should not use recycled materials or materials that can cause adverse reactions, and should not undergo chlorine bleaching; A mask equipped with a breathing valve should have a firm and non deformable breathing valve, and the internal components should not fall off; Lace-up mask straps should not be used; The nose clip should withstand 20 folds without breaking; The inner material of the mask should not be printed or dyed. The standard strictly stipulates the residue of harmful substances, with a formaldehyde content not exceeding 20mg/kg The printed pattern on the outer layer of the mask should not fade, and decomposable carcinogenic aromatic ammonia dyes are prohibited; The residual amount of ethylene oxide sterilization shall not exceed 2 μ G/g; No transferable fluorescent whitening substances shall be detected

Test items for children's masks:

The test items for children's masks mainly have clear regulations from three aspects: basic requirements, appearance requirements, and internal quality requirements.

1. Basic testing requirements:

Children's masks should be equipped with nose clips and made of plastic materials, which can firmly protect the mouth and nose; It should not have exposed metal objects or sharp tips or edges that may cause harm to children; The raw materials are required to have no odors, and recycled materials cannot be used. Toxicological skin irritation tests, harmful substance limits, and other requirements must be passed, and chlorine bleaching is not allowed; Children's masks cannot be tied up, have detachable small parts, and are easy to carry and remove. When worn, there should be no pressure or tenderness, and the impact on head movement should be minimal

2. Appearance inspection requirements:

The appearance of children's masks requires that the surface should not have any obvious defects such as damage, oil stains, deformation, etc. The materials that come into contact with the skin should not be dyed.

3. Internal quality inspection items:

; Color fastness to dry friction, color fastness to saliva, formaldehyde content, pH value, decomposable carcinogenic aromatic amine dyes, residual amount of ethylene oxide, nose clip length, fracture strength of mask straps and their connection with the mask body, inhalation resistance, exhalation resistance, protective effect, filtration efficiency, ventilation resistance, visual field below the mask, flame retardant performance, respiratory valve cover fastness, and microbial indicators. The microbial detection indicators mainly include Escherichia coli group, pathogenic pyogenic bacteria (Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus hemolyticus), total number of fungal colonies, and total number of bacterial colonies

Testing standards:

Standard category, standard number, standard name, mandatory national standard GB "Technical requirements for medical protective masks" GB 2626-2006 "Respiratory protective equipment - Self suction filter type anti particle respirator" (invalid date: 20200701) GB 2626-2019 "Daily protective masks and technical specifications" Recommended national standard GB/T 32610-2016 "Technical specifications for daily protective masks" Mandatory industry standard YY 0469-2011 The recommended industry standard YY/T 0969-2013 "Disposable Medical Masks" is the American standard ASTM F20100-2019 "Standard Specification for Material Performance of Medical Masks" and the European standard EN "Requirements and Test Methods for Medical Masks".

Wearing Safety Warning:

The recommended national standard "Technical Specification for Children's Masks" provides clear safety warnings for the use of children's masks, For example:

Children should wear masks under the supervision of adults, and caregivers should pay attention to observing and educating children to wear masks correctly Children should not play or engage in moderate to moderate intensity exercise while wearing masks, and should not disassemble the breathing valve and its internal components If symptoms such as respiratory discomfort and skin allergies occur during wearing, the mask should be removed in a timely manner, and if necessary, medical attention should be sought immediately Masks should be replaced in a timely manner. 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. When using, items unrelated to the wearing of the mask should be removed, etc
