Protection and barrier effect

Determination of breathability (differential pressure) on surgical masks

Regulatory reference:	UNI EN 14683:2019.
Claim:	Determination of breathability
Application field:	Raw materials and finished products.
Description of the test:	Determination of the differential pressure is an indicator of the “breathability” of the mask. Air permeability is measured by determining the pressure difference across the mask under specific conditions of airflow, temperature and humidity.
