EN 17272 evaluates automated airborne disinfection system. The term 'airborne' describes the manner by which the disinfectant is dispersed, either by gaseous, vapor, and/or aerosolized form. The air isn't disinfected, but rather the surfaces present in the enclosed space like table tops.

EN 17272 consists of two mandatory tests. Click here to learn more about them.
CUSTOMER PROCESS
Step 1: Distribution test

The purpose of distribution test is to evaluate the effectiveness of your device distributing its synergistic disinfectant solution in an enclosed space.

  • Test Organisms: Staphylococcus aureus
  • Sampling points: 8 carriers  (Blue Test Zones)
  • Airborne Disinfection Contact Time: Pre-determined by manufacturers
Step 2: Efficacy testing

Pick the target area of disinfection system application:

  • Medical Area
  • Veterinary Area
  • Food, Industrial, Domestic and Institutional Areas

Choose antimicrobial activity spectrum:

  • Bactericidal Δ
  • Yeasticidal Δ
  • Fungicidal
  • Virucidal
  • Tuberculocidal
  • Mycobactericidal
  • Sporicidal
  • Phagocidal *

Δ Minimum requirement activity                                     * Applicable in food industry area only

Step 3: Select an appropriate contact time

Aerosolization Disinfection Contact Time is pre-determined by manufacturers.

Step 4: What are the soiling conditions associated with your test product?

Interfering substances, or commonly referred to as soiling, are used to mimic organic substances found on human skin, surfaces, and instruments. These are the available soiling conditions according to the target area:

Medical Area:

  • Clean condition: 0.3 g/L bovine serum albumin
  • Clean condition for sensitive microorganisms: 0.3 g/L bovine serum albumin + milk 1/20
  • *Dirty condition: 3 g/L bovine serum albumin + 3 mg/L erythrocytes

Veterinary Area:

  • Low level dirty condition: 3.0 g/L bovine serum albumin
  • Low level dirty condition for sensitive microorganisms: 3.0 g/L bovine serum albumin + milk 1/20
  • *High level dirty condition: 10 g/L bovine serum albumin + 10 g/L yeast extract
  • *High level dirty condition for sensitive microorganisms: 10 g/L bovine serum albumin + 10 g/L yeast extract + milk 1/20

Food, Industrial, Domestic and Institutional Areas:

  • Clean condition: 0.3 g/L bovine serum albumin
  • Clean condition for sensitive microorganisms: 0.3 g/L bovine serum albumin + milk 1/20
  • *Dirty condition: 3.0 g/L bovine serum albumin
  • *Dirty condition for sensitive microorganisms: 3.0 g/L bovine serum albumin + milk 1/20

*Optional for manufacturers

Step 5: Place an order and send your sample to us

Fill in the test request form and place an order via email at info@tecolab-global.com.

You can deliver the Airborne Disinfection System to us via courier and provide us the tracking code. We will monitor the delivery status and inform you when we receive the system.

Step 6: Track the status of your request

Once we have received your Airborne Disinfection System, we will provide a tracking number to you. You can easily track the status of your request here.

Step 7: Download your password-protected test report

Download your readily available test report online with just a single click using the link and password provided via email notification. We will receive a notification once you have downloaded the test report.

For safety purposes, the uploaded test report will self-destruct after 7 days.

Step 8: Analyze your passing criteria in the test report with our laboratory experts

In order to pass the test, the product shall demonstrate these log reductions in the medical area, veterinary area and food, industrial, domestic and institutional area.

  1. 5 decimal log (lg) reduction for bactericidal activity
  2. 4 decimal log (lg) reduction for yeasticidal and/or fungicidal activity
  3. 4 decimal log (lg) reduction for virucidal activity
  4. 3 decimal log (lg) reduction for sporicidal activity (Please note a 4 decimal log reduction is required in the medical area)
  5. 4 decimal log (lg) reduction for phagocidal activity
  6. 4 decimal log (lg) reduction for mycobactericidal activity
