EN 14476: Chemical disinfectants and antiseptics - Virus killing quantitative suspension test for chemical disinfectants and antiseptics used in medicine

EN 14476 is an international standard that assesses the virucidal efficacy of disinfectants. This test measures the capacity of a disinfectant to destroy or inactivate viruses over a specified period of time. It is applied to verify the effectiveness of disinfectants used in critical areas such as health, food and industry.

What is the Purpose of the EN 14476 Standard?

EN 14476 standard, disinfectants:

To determine its efficacy against viruses of human and animal origin,
To assess the suitability of disinfectants used in public health critical areas,
It has been developed to contribute to the control of infectious diseases by preventing the spread of viruses.

What is the Scope of the EN 14476 Standard?

The EN 14476 standard applies virucidal efficacy assessment in the following situations:

Healthcare: Hospital surfaces, medical devices, hand sanitizers.
Food Industry: Disinfection of food processing equipment.
General Hygiene: Surface disinfectants used in areas such as offices, schools, homes.
Animal Husbandry and Veterinary Areas: Disinfection of animal shelters and equipment.

What are the Application Areas?

Applicable for products with claimed disinfectant efficacy against viruses.
Applicable to products to be used for surface, skin or industrial disinfection.
Applicable for chemical disinfectants and antiseptics to be used in areas and situations where disinfection or antiseptic care is required: Hospitals, schools, kindergartens and nursing homes and the workplace, public places and homes, laundries and kitchens providing products to patients...

A test based on 5 steps is performed to confirm virucidal efficacy:

Calculation of virus titer (virus control)
Measurement of the cytotoxicity of the tested disinfectant
Detection of cellular susceptibility to the virus
Neutralization control of the tested disinfectant
Virus inactivation at 30 min and 60 min contact time with formaldehyde

When the above-mentioned test procedures meet the method criteria and the tested disinfectant meets the 4 log reduction compared to the initial virus titer at the end of the contact time with the virus, it can be said that “Disinfectant is Effective Against Virus ”.
