TS EN 13624 Chemical Disinfectants and Antiseptics

The EN 13624 standard, a European standard, describes the requirements and test methods for evaluating the fungicidal effectiveness of chemical disinfectants used in medical devices.

TS EN 13624 Chemical Disinfectants and Antiseptics

This standard has been published in our country by the Turkish Standards Institute (TSE) with the following title: TS EN 13624 Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of the fungicidal effectiveness of chemical disinfectants used in medical devices - Test method and requirements (step 2, step 1).

The standard in question describes the minimum requirements for fungal or yeast-killing activity of chemical disinfectant products that form a homogeneous and physically stable preparation when diluted with hard water or water in ready-to-use products.

In general, these chemical disinfectants and antiseptics are tested at a concentration of 80 percent or less, as some dilution is made by adding test organisms and compounds.

Organisms that are mandatory to determine fungicidal activity are Candida albicans and Aspergillus brasiliensis. Depending on their use, the following tests are carried out under minimum test conditions:

  • Rubbing of hands (hand scrub) or hygienic hand washing: Candida albicans are used as test strains, the test temperature is kept at 20 degrees, the contact time is 30 to 60 seconds, and the test is carried out in clean or dirty conditions.
  • Friction (surgical hand scrub) or surgical hand wash: Test strain Candida albicans is used, the test temperature is kept at 20 degrees, contact time is 1-5 minutes, and the test is carried out in clean or dirty conditions.
  • Disinfection of medical equipment: For fungicidal activity, Aspergillus brasliensis and Candida albicans are used, the test temperature is between 20-70 degrees, the contact time is kept for a maximum of 60 minutes, and the test is carried out in clean or dirty conditions.
