摘要

Currently, protective mask seal designs are evaluated indirectly by measuring fit factor (FF), a ratio of the concentration of particles outside versus inside the mask. This paper describes an alterante process for evaluting mask seals by measuring the pressure distribution between the seal and face. The goal was to develo pa relationship between FF and seal pressure. The FF and seal pressure relationship could be used to predict the seal pressure necessary to provide a specific FF or determine whether the seal pressure provided by a mask prototype is sufficient to meet a protection or FF requirement.
