Introduction
The use of community face coverings was acknowledged during the SARS-CoV-2 pandemic as part of a
comprehensive strategy of measures. They are intended for use by people in areas of known or suspected
community or cluster transmission of respiratory infection. Typically, the general public wear community
face coverings in indoor (for example, shops, shared workplaces, schools, transport, etc.) and outdoor
settings where physical distancing can be impractical. Further guidance on where the general public may
be encouraged to use community face coverings, is given by national or local health authorities and
[1]
through World Health Organization recommendation .
Community face coverings are not suitable for children up to 4 years of age. It is recommended that
children between 4 and 12 years of age are supervised while wearing the community face covering.
NOTE 1 The minimum age criteria can be higher if required by national legal provisions or as advised by national
health professionals.
The wearing of a community face covering, schematically shown in Figure 1, reduces the
projection of the wearer's respiratory droplets of saliva, sputum or respiratory secretions when
talking, coughing or sneezing. A community face covering might also reduce penetration of the
respiratory droplets from an external source to a wearer’s nose and mouth, without claiming
protection for the wearer. It might also reduce how often a wearer touches his/her face with the
hands.
Figure 1 — Limitation of the respiratory droplets projection to the environment
This document specifies the functional and performance levels for community face coverings together
with information for use, marking, labelling and packaging. The appropriate test methods are also
defined.
IMPORTANT — Community face coverings are not subject to a mandatory conformity assessment
by notified bodies or laboratories. Their design in accordance with accepted best practices and
production quality control remain the producer's responsibility. The producer may need to call
upon a laboratory to verify the required performance.
IMPORTANT — The community face coverings specified in this document are not medical devices
(MD) within the meaning of Regulation EU/2017/745, nor are they personal protective
equipment (PPE) within the meaning of Regulation EU/2016/425.
The informative Annex G lists topics of further investigation which might lead to necessary improvement
of the safety requirements of the community face coverings.

1 Scope
This document specifies the minimum requirements for reusable or single use community face coverings
intended for the general public, covering the nose, mouth and chin (for minimum coverage area, see
Figure 2) in order to reduce the risk of droplet/aerosol projection towards nearby people. These
requirements include:
— innocuousness,
— design (including fit),
— performance,
— test methods,
— marking,
— packaging,
— information for use.
Figure 2 — Community face coverings minimum coverage area (dark area)
These requirements are applicable to:
— community face coverings made of one or multiple fabric layers (including woven, knitted,
nonwoven), and including community face coverings with a removable filter in between the layers;
— community face coverings including a transparent window which allows for the wearer's mouth and
facial expressions to be seen, in order to facilitate full facial recognition, lip reading and/or sign
language alongside other methods of communication (see A.6);
— structured community face coverings including moulded plastic shells and rigid face coverings'
components.
This document is not intended for community face coverings for children up to 4 years of age (it means
until 3 years and 11 months) (see A.1).
This document is not intended for medical face masks (medical devices specified in EN 14683), nor for
filtering masks to protect against particles (personal protective equipment specified in EN 149).
This document excludes impermeable nose and mouth shields (including visors) and face coverings
incorporating inhalation and/or exhalation valve(s) (see A.2).
