Description

ASTM F3502-21 is primarily intended to help ensure barrier face coverings meeting the stated requirements provide (1) a means of source control for individual wearers by reducing the number of expelled droplets and aerosols from the wearer's nose and mouth into the air; and (2) to potentially offer a degree of particulate filtration to reduce the amount of inhaled particulate matter by the wearer.
