water aerosol filtration efficiency with bacteria (BFE),
water aerosol filtration efficiency with viruses (VFE),
pollen particle filtration efficiency, and
differential pressure.

This document specifies the following safety items:

free formaldehyde,
specific azo dye,
heavy metals, and
pH.

This document applies to nonwoven general use face coverings. It does not apply to medical face masks (see EN 14683 [5]), medical devices, or personal protective equipment (PPE) in the scope of ISO/TC94/SC15, Respiratory protective devices (RPD).
