Scope

Main Technical Content: (1) Structure and Scope of the Standard This standard includes eight chapters: Scope, Normative References, Terminology and Definitions, Classification and Specifications, Requirements, Test Methods, Inspection Rules, and Marking, Packaging, and Storage. The standard specifies that the disposable children's masks are intended for children aged 3-14, to be worn in ordinary environments to block the transmission of droplets, pollen, microorganisms, and other particulate matter. The standard does not apply to masks with breathing valves. The target user group of the disposable children's masks is primarily students in kindergartens, primary schools, and middle schools. As children grow older, their respiratory volume increases, and by age 14, it approaches that of adults. Medically, children under 14 are typically considered the age group for medical observation. (2) Discussion of Main Technical Indicators, Parameters, and Test Verification 1. Terminology and Definitions The standard defines four terms: particulate matter, filtration efficiency, bacterial filtration efficiency, and airflow resistance. The definition of particulate matter follows the standard "Selection, Use, and Maintenance of Respiratory Protection Products" (GB/T 18664-2002), the definition of filtration efficiency follows the standard "Self-Suction Filter-Type Particulate Respirators for Respiratory Protection" (GB 2626-2019), and the definition of bacterial filtration efficiency follows the standard "Disposable Medical Masks" (YY/T 0969-2013). 2. Classification and Specifications Masks are divided into flat and foldable types, and are available in three sizes: small (3-6 years), medium (7-12 years), and large (13-14 years). Due to the lack of statistical analysis data on the sizes of various types and sizes of masks, the standard does not provide recommended sizes, but clearly specifies size deviations in the requirements. 3.
