Airborne disinfection by automated process

(BS EN 17272:2020: Chemical Disinfectants and Antiseptics – Methods of airborne room disinfection by automated process – Determination of bactericidal, mycobactericidal, sporicidal, fungicidal, yeasticidal, virucidal and phagocidal activities.)

While fogging machines are not new, they have risen to prominence during the pandemic, because they are able to sanitise large internal spaces, common touch surfaces, and hard-to reach areas effectively. Technically speaking, automatic foggers, together with their disinfectants, are known as ‘automated airborne systems or solutions’.

Prior to October 2020, regulators have required efficacy data produced using the French standard NFT 72-281. However, the new European standard EN 17272 has replaced this, so manufacturers now need to have their systems re-tested to ensure compliance.

We are proud to add the BS EN 17272:2020 test to our roster of services and to be the UK’s only independant commercial microbiological testing company currently offering this in-house. This offers companies the opportunity to have their automated airborne systems independently validated in the UK, saving the stress and expense of getting them to mainland Europe, especially pertinent in light of the current challenges prompted by both coronavirus and Brexit.

What does the test involve? 

The BS EN 17272:2020 standard determines the disinfectant activity of processes used in the medical, veterinary, food, industrial, domestic, and institutional areas, using automated processes for distributing chemicals by air diffusion with no operator manually applying the disinfectant. This includes the disinfection of nonporous surfaces but not that of the air.

Our experienced team can perform the test in our new building, which has been specially commissioned for this process. The method involves placing a small number of test organisms or virus on stainless steel discs and placing them around the room, according to defined standards. The customer’s system (machine and solution) is then left to run for its cycle. At the end of the test, the amount of organisms or virus surviving on the discs is counted.

This test data can then be used to report the specific disinfectant activity of the automated airborne disinfection system (labelled BS EN 17272:2020). It should also be noted that the EN 17272 is not only applicable to whole room disinfection, small enclosures such as biosafety cabinets and hatcheries also require testing under different conditions. Our purpose-built brand new lab is also equipped for small enclosure testing.

How long will it take?

The test can take several weeks per product, dependent on the number of organisms that the customer wishes to test for, and demand is already high. We will be working to a queuing system and will contact you with an estimated testing start date when you are nearing the front of the queue.
