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.
The purpose of this document is to describe a test method for assessing the disinfectant activity of
airborne surface disinfection processes under a specific experimental condition.
— Part 1 – Efficacy test; intended to ensure that minimum efficacy requirements are fulfilled for each type of activity claimed and for the targeted application area(s).
— Part 2 – Distribution test; intended to ensure efficacy of the process throughout the enclosure, It is performed with a reference test organism at 4 sampling positions.
The processes concerned include those involving chemical disinfectants in dispersed gaseous, vapour and/or aerosolised form.
Every automated airborne disinfection cycle/application is unique and the purpose of this document is to provide a defined challenge for the automated airborne disinfection system to successfully meet in order to be considered an efficacious process. This standard method should therefore be regarded as a useful starting point and not as a validation for all intended treatments with a particular automated airborne disinfection system.
The aim of this document is to simulate practical conditions of airborne disinfection in a l situation; obligatory conditions are defined according to the test method defined below conditions are also proposed.
The test report specifies and summarizes the conditions under which the tests are carried out.
