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.

Bacterial Filtration Efficacy (BFE) testing according to ISO 14683

Regulatory reference: ISO 14683:2019 (B).
Claim: BFE (Bacterial Filtration Efficiency)
Application field: Raw materials and finished products.
Description of the test: Bacterial Filtration Efficacy (BFE) testing according to EN 14683:2019 (B) through Andersen six stage viable impactor. The analysis is performed on textile samples for the production of surgical masks or on finished surgical masks.
Abich successfully took part in the first Interlaboratory BFE Round-Robin organized by a certified ISO/IEC 17043 provider to guarantee the accuracy of analytical data for surgical masks testing.
