Scope

Scope: This standard specifies the grading and marking, technical requirements, test methods, inspection rules, labeling, packaging, transportation, and storage of polypropylene meltblown nonwoven fabrics for masks. It is applicable to nonwoven fabrics made from polypropylene as the main raw material and using the meltblown process for the production of masks. Main technical content: This standard specifies the technical requirements, test methods, inspection rules, labeling, packaging, transportation, and storage of polypropylene meltblown nonwoven fabrics for masks. The technical requirements of meltblown nonwoven fabrics include two parts: internal quality and appearance quality indicators. The indicators for each part are set considering three aspects: avoiding quality risks, controlling the quality of masks from the source of production, and improving the protective safety performance and wearing comfort of masks.
