This standard applies to children aged 6-14 and is the first child mask standard published in China and the world.
Children's masks are divided into two types according to their performance. Protective children's masks are mainly three-dimensional, suitable for medium pollution or potentially medium risk environments. Hygienic children's masks are mainly flat, which can be used in low-pollution or low-risk environments, such as restaurants, classrooms, and dormitories during events such as influenza. Compared with adult masks, the standard protective performance of children's masks is not lower than that of adult masks.
Compared with adults, the development of cardiopulmonary function in children aged 6-14 is very different, especially in young children whose cardiopulmonary function is weak and the damage is irreversible. The children's mask standard greatly reduces the respiratory resistance and ventilation resistance indicators, and the standard recommends the use of adjustable mask straps to fully improve children's wearing comfort.
