BS EN 17915 : 2022 - Test method for the evaluation of virucidal activity of chemical disinfectants on hard non-porous surfaces in food, industrial, domestic, and institutional areas (phase 2 step 2)
Application
- Murine Norovirus
- Adenovirus
- Vaccinia Virus
- Murine Parvovirus
- Test virus suspension with interfering substance is inoculated onto a test surface and dried.
- Dried inoculated surface is exposed to disinfectant for specific contact times.
- At the end of contact time, the disinfectant activity is neutralized.
- Infectious titre of virus recovered is determined and compared with infectious titre from control test.
- Ensures the development of innovative disinfectant formulations tailored to meet high standards of virucidal activity.
- EN 17915 validates disinfectants for diverse areas such as food preparation, industrial facilities, domestic spaces, and institutional environments.

Abstract
EN 17915 standard specifies the test method to determine virucidal activity of disinfectants on non – porous surfaces without mechanical action. EN 17915 test is applicable to disinfectant products used in food, industrial, domestic, and institutional areas, except for the situations where disinfection is medically indicated and excluding products used on living tissues.
EN 17915 is a carrier test method (phase 2, step 2) that aims at determining the efficacy of disinfectants under more realistic conditions.
EN 17915 Test Conditions & Requirement
Minimum test conditions and parameters specified by EN 17915 standard are as follows –
Minimum conditions | Surfaces disinfection in industries, food processing, distribution and retailing areas | Surfaces disinfection in institutional and domestic areas |
Mandatory test organisms | Virucidal activity for biopharmaceutical industry Murine Parvovirus Virucidal activity for industries other than biopharmaceutical and food industry Adenovirus (ATCC VR-5) Murine Norovirus (FLI S99) Virucidal activity for food industry Murine Norovirus (ATCC VR-5) Virucidal activity against enveloped viruses Vaccinia virus (ATCC VR-1549) Virucidal activity (chemo-thermal) Murine Parvovirus for temperatures >40ยฐC | Virucidal activity for institutional and domestic use Adenovirus (ATCC VR-5) Murine Norovirus (FLI S99) Virucidal activity against enveloped viruses Vaccinia virus (ATCC VR-1549) |
Test temperature | between 18 ยฐC and 25 ยฐC but for chemothermal activity | between 18ยฐC and 25 ยฐC |
Additional temperature | between 4 ยฐC and โค 40 ยฐC | between 4 ยฐC and and โค 40 ยฐC |
Contact time | As per manufacturer’s recommendations , but not longer than 60 min | As per manufacturer’s recommendations , but not longer than 60 min |
Interfering substance Clean conditions | 0,3 g/l bovine serum albumin | 0,3 g/l bovine serum albumin |
Dirty conditions | 3,0 g/l bovine serum albumin | 3,0 g/l bovine serum albumin |
EN 17915 Test Method
- Test suspension of virus with interfering substance is inoculated onto a test surface and dried out.
- Disinfectant sample is evenly spread on dried microbial film and allowed to interact for specific contact times. In parallel, a control test is run wherein the virus infected test surface is treated with hard water instead of disinfectant.
- At the end of contact time, the test surface is immediately transferred to the cell maintenance medium to neutralize further activity of the disinfectant sample.
- Infectious titre of virus recovered in cell maintenance medium is determined and compared with infectious titre from control test.
Importance of EN 17915 Test
Many viruses exhibit the ability to survive on hard surfaces for an extended period and remain infectious. The process of disinfection plays a crucial role in elimination of harmful viruses and ensures a safe and hygienic environment. Not all available disinfectants are capable of effectively killing viruses. It is essential to use disinfectants formulated with virucidal agents for effective virus disinfection.
As per European norms, disinfectants claiming virucidal activity must be tested for their efficacy under standardized methods. The European Standard EN 17915 has been devised to check the virucidal efficacy of non-porous surface disinfectants before their intended applications.
