BS EN 14562 : 2006 – Quantitative carrier test for the evaluation of fungicidal or yeasticidal activity for instruments used in the medical area (phase 2, step 2)
EN 14562 specifies test conditions and efficacy criteria for chemical disinfectants and antiseptics claiming fungicidal or yeasticidal properties. This standard is applicable to products intended to be used for instrument disinfection in medical areas.
EN 14562 is a (phase 2, step 2) carrier test. The aim of the test is to simulate real-world conditions to evaluate the effectiveness of disinfectants for their intended use. EN 14562 test is performed by selecting a suitable carrier material that closely resembles the type of surfaces used in practical settings.
EN 14562 Test Conditions & Requirement
- Mandatory test microorganisms:
- Fungicidal activity – Candida albicans (ATCC 10231), Aspergillus niger (ATCC 16404) (formerly Aspergillus Brasiliensis)
- Yeasticidal activity – Candida albicans (ATCC 10231)
- Test temperature – 20 °C
- Contact time – 60 mins
- Interfering substance:
- Clean conditions – 0.3 g/l bovine albumin solution
- Dirty conditions- 3.0 g/l bovine albumin solution + 3.0 ml/l washed sheep erythrocytes
- Log reduction – Test product must demonstrate at least 4 log reduction values against mandatory test microorganisms
EN 14562 Test Method
- A test suspension of microorganisms (yeast or fungus) with an interfering substance is inoculated onto a glass surface (carrier). This is left to dry naturally.
- Inoculated carrier is immersed into disinfectant solution and maintained at 20 °C for 60 mins. In parallel, a control test is run where the glass carrier is immersed in hard water (control sample) instead of disinfectant.
- At the end of contact times, the carrier is transferred into a neutralizing solution containing glass beads. The solution is shaken to separate yeast/fungal spores from the glass surface.
- Neutralizing solution is then plated and incubated to determine the number of viable cells present in the sample.
- Microorganisms from both treated carrier and control test (carrier treated with hard water instead of disinfectant) are enumerated and reduction in microbial count is calculated.
Importance of EN 14562 Test
In hospital environments, Candida and Aspergillus are found responsible for causing opportunistic infections, especially in immunocompromised patients. One of the major contributing factors to these infections is improper sterilization and disinfection of medical equipment, instruments, and devices.
Therefore, disinfection of instruments is regarded as a crucial hygiene practice in healthcare settings to prevent fungal infections.
In Europe, regulatory approval is mandatory for manufacturers/companies of medical instrument disinfectant products before market release of their products. EN 14562 standard outlines conditions and test parameters to assess efficacy of disinfectant products against Candida albicans and Aspergillus niger.
