ISO 22196: Measurement of Antibacterial Activity on Plastics and Other Non-Porous Surfaces

ISO 22196 specifies a quantitative method to assess the antibacterial activity of plastics and other non-porous surfaces. The test determines how effectively a material inhibits the growth of bacteria, which is essential for applications in healthcare, food packaging, consumer goods, and more.

Key Features of ISO 22196:

• Scope: Evaluates antibacterial activity on plastics and non-porous surfaces
• Bacteria Used: Staphylococcus aureus and Escherichia coli
• Test Methodology:
  • Bacterial suspension is applied to both treated and untreated samples
  • Incubation under controlled conditions, usually at 35°C
  • Measure surviving bacteria after 24 hours
  • Calculate antibacterial activity (log reduction)

Why Choose ISO 22196 Testing?

• Internationally Recognized: ISO 22196 is accepted worldwide as a reliable method for assessing antibacterial effectiveness.
• Comprehensive Assessment: The standard evaluates both gram-positive and gram-negative bacteria, ensuring broad-spectrum analysis.
• Quantitative Results: Provides clear, numerical data to demonstrate antibacterial performance.
