Respirator performance rating table for mask design.
The ultimate goal for respirator mask designers is computer-aided design. Mask design, however, is a very complex operation, with many different interrelationships. Current knowledge does not allow significant incorporation of physiological information into mask design. Rather, physiological information is usually gathered during mask evaluation, after the design process has been completed. The Performance Rating Table (PRT) is a beginning step to formulating physiological knowledge in a way that can be useful for design. The PRT organizes physiological knowledge to assign performance data to various mask and level of work causes. Best estimates of tabled values were obtained from the literature.
