BS EN 14563: 2008 - Quantitative carrier test for the evaluation of mycobactericidal or tuberculocidal activity of chemical disinfectants used for instruments in the medical area
Application
- Mycobacterium avium
- Mycobacterium terrae
- Test suspension mixed with interfering substances is spread on sterile glass slides and dried.
- Slides are exposed to the disinfectant for the specified contact time.
- At the end of the contact time, slides are neutralized followed by plating and incubation to determine viable cells.
- Test specifically assesses the products for mycobactericidal or tuberculocidal activity.
- Supports healthcare facilities to reduce the risk of infection transmission by validating product efficacy.

Abstract
EN 14563 specifies a test method to assess the efficacy of instrument disinfectants against mycobacteria.
EN 14563 standard is applicable to areas and/or situations where disinfection is medically indicated –
- hospitals,
- community care centres,
- dental care settings,
- nursing homes,
- and laundries and kitchens providing services directly to patients.
EN 14563 Test Conditions & Requirements
Mandatory test microorganisms
- Mycobactericidal activity – Mycobacterium avium and Mycobacterium terrae
- Tuberculocidal activity – Mycobacterium terrae
Test temperature โ 20 ยฐC
Contact time โ 60 minutes
Interfering substance โ Clean Conditions: 0.3g/l bovine albumin solution and dirty condition: 3.0 g/l bovine albumin solution + 3.0 ml/l erythrocytes

EN 14563 Test Method
- Test suspension is mixed with an interfering substance and spread onto sterile glass plates. Inoculated slides are allowed to dry out.
- Inoculated dried slides are kept in a container containing test products for a specific contact period time. In parallel, water (control sample) is challenged with test microorganisms.
- At the end of contact period, glass slides are further transferred into neutralizing solution.
- Neutralizing extract is plated and incubated to determine viable cells.
- After incubation, bacterial colonies are enumerated and results are compared to the control sample.
Importance of EN 14563 Test
To prevent the transmission of mycobacterial infections in hospital environments, medical instruments must be disinfected with products possessing tuberculocidal and mycobactericidal action.
European standard EN 14563 provides a quantitative carrier test for evaluation of the mycobactericidal activity of disinfectants under practical conditions. Evaluation test is carried out for manufacturer’s instrument disinfectant products to ensure efficacy against mycobacteria.
