This method is dedicated to determine the antimicrobial activity of steam disinfection devices. Steam disinfection device is generally operated by releasing water vapour at high temperatures allowing the destruction of microorganisms.

Pick the targeted area of application:

• Medical area
• Veterinary area
• Food, industrial, domestic and institutional areas

Choose your preferred antimicrobial activity spectrum:

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

Passing speed and number of passes dictates exposure of the surface to the disinfection process by how fast the device is moved from A to B and how many times the device is passed between A and B. The minimum and obligatory passing speed given by the test method is 10 cm/s.

Distance corresponds to how far is the device to the test surface. There are 2 uses of the steam disinfection device according to manufacturer’s instruction, with contact and without contact. In the case of “with contact”, distance shall be < 5 mm and the mechanical effect is considered in the evaluation. In the case of “without contact” disinfection, the minimum distance given by the test method is 5 mm.

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:

• Dirty condition: 3.0 g/L bovine serum albumin + 3.0 mL/L erythrocytes
• Dirty condition for sensitive microorganisms: 3.0 g/L bovine serum albumin + 3.0 mL/L erythrocytes + reconstituted skimmed milk 1/5

Veterinary Area:

• 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 + reconstituted skimmed milk 1/5

Food, Industrial, Domestic and Institutional Areas:

• Dirty condition: 3.0 g/L bovine serum albumin
• Dirty condition for sensitive microorganisms: 3.0 g/L bovine serum albumin + reconstituted skimmed milk 1/5

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

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
5. 4 decimal log (lg) reduction for phagocidal activity
6. 4 decimal log (lg) reduction for mycobactericidal activity
