Scope

Main Technical Content: (1) Structure and Scope of the Standard This standard specifies the terms and definitions, requirements, test methods, inspection rules, and classification for daily protective masks. It applies to masks made from non-woven fabrics or woven materials, used to filter out dust, pollen, willow catkins, and bacterial particles in daily life, and to block respiratory tract contaminants such as nasal or oral expired breath and droplets. The standard does not apply to respiratory protection products for special industries such as oxygen-deficient environments, underwater operations, escape situations, firefighting, medical applications, or industrial use. The standard also excludes masks intended for infants and young children aged 36 months and below. (2) Discussion of Main Technical Indicators, Parameters, and Test Verification 1. Terms and Definitions This section defines terms such as "particle filtration efficiency," "bacterial filtration efficiency," and "children's masks" and "elderly masks." Children's and elderly masks are a unique feature of this standard, and the definitions for these two types of masks are specified here. 2. Classification and Specifications Masks are categorized by structure type (flat masks and foldable masks) and by age group (adults, children, and elderly). They are further classified by filtration grade (Level 1, 2, and 3) and by size (large, medium, and small). 3. Requirements (1) Basic Requirements They must comply with the basic requirements of GB/T 32610-2016. (2) Appearance and Dimensional Tolerances The mask's appearance and dimensions should be clean and intact, with no damage or stains on the surface. The nose clip should be made of a flexible material. When worn, the mask should cover the wearer's mouth, nose, and chin. The dimensions must meet design specifications, with a maximum tolerance of ±5%. The folding ratio of flat disposable masks should be no less than 50%. (3) Inter
