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.

Determination of antiviral activity of textile products according to ISO 18184:2019 (E)

Regulatory reference: ISO 18184:2019 (E).
Claim: Antiviral activity
Application field: Raw materials and finished products.
Description of the test: The test can be performed on textiles (wool, fibers, spun materials, bundles, knitwear fabrics). Tested products can be used in hospitals and healthcare facilities, or as upholstery materials on transports. The virus strands used in the test are “Type A flu” and “Feline carcinovirus”. Other virus strands can be tested upon requests, following a feasibility study.

LAL (Lysate of Limulus Amaebocytes) test

Regulatory reference: USP85.
Claim: Absence of bacterial endotoxins
Application field: Medical devices: raw ingredients and finished products.
Description of the test: Lysate of limulus amaebocytes (LAL) is an acqueous extract obtained by Limulus polyphemus amaebocytes. The LAL reacts strongly to endotoxins in Gram-negative bacterial membranes (lypopolysacchartides), resulting in coagulation. This property is exploited in the LAL test to detect endotoxins.
