Testing of surgical masks
Surgical masks – also known as medical face masks – are loose-fitting disposable masks that cover the nose and mouth, forming a barrier between the wearer's mouth and nose and potential contaminants in the immediate environment.
Surgical masks are typically made from a combination of different types of non-woven fabrics, such as polypropylene, polyester, and rayon. They have water-repellent layers, internal filter layers, and adjustable straps to ensure a snug fit. They are designed to filter out large particles such as dust, pollen, and airborne pathogens to help reduce the risk of infection. The masks are categorized as Type I, Type II, and Type IIR depending on their performance.
How surgical masks are tested
Surgical masks are tested in accordance with the requirements of EN 14683:2019+AC:2019, which is a harmonized European standard covering the safety and performance requirements for medical face masks. Testing includes assessment of bacterial filtration efficiency, fluid resistance, cleanliness, and breathability. The tests are often performed by third-party certification bodies and notified bodies.
How to proceed
Users, manufacturers, and importers can have masks tested according to EN 14683:2019+AC:2019 at the Danish Technological Institute. If you need samples to be taken on a statistical basis, we can also perform this using DS ISO 2859-1 as a basis. Finally, if you are uncertain about the quality of a test report, we are happy to review the material and assess whether additional testing is necessary.
Are the masks too old?
If you have acquired large quantities of protective equipment, it may happen that some masks exceed their expiration date. To determine whether these masks still provide sufficient protection, we now offer testing of stored masks. Furthermore, our accredited test laboratory can assess the possibility of extending the masks’ shelf life, for example by two years.
If you have face masks that you would like tested, you can send the product to:
