This document specifies construction, design, performance requirements and test methods for medical
face masks intended to limit the transmission of infective agents from staff to patients during surgical
procedures and other medical settings with similar requirements. A medical face mask with an
appropriate microbial barrier can also be effective in reducing the emission of infective agents from the
nose and mouth of an asymptomatic carrier or a patient with clinical symptoms.
This European Standard is not applicable to masks intended exclusively for the personal protection of
staff.
NOTE 1 Standards for masks for use as respiratory personal protective equipment are available.
NOTE 2 Annex A provides information for the users of medical face masks.
