The European Commission has updated its Q&A document on conformity assessment procedures for protective equipment like face masks, gloves, coveralls, etc.
The corresponding document can be downloaded here.
Furthermore, the European Committee for Standardization (CEN) has published a guidance document on community face masks. From a regulatory perspective, community masks do not fulfill the definition of a medical device or PPE. Still, the document may be helpful for manufacturers of these products to maintain minimum quality standards. Please get in touch should you require a copy of the document.
