What Is ASTM F3502 Face Covering Barrier?
ASTM F3502-21 specifies performance requirements for barrier face coverings designed to reduce the transmission of respiratory droplets and aerosols. The standard evaluates filtration efficiency and airflow resistance to ensure that face coverings provide effective source control while maintaining breathability.
This specification is widely used for non-medical face coverings intended for public use. It supports consistent evaluation of materials and designs to ensure that barrier face coverings meet defined performance criteria for filtration and comfort.
