Evaluation of antibacterial/antifungal properties of materials

To support manufacturers committed to responding to the growing demand for potentially aseptic products to be used not only in the healthcare sector, but also at home, CSI has launched a testing service to measure the antibacterial capacity of plastics and other non-porous hard surfaces.


Services offered in detail 


Measurement of antibacterial activity

Reference standard: ISO 22196

Tests carried out according to ISO 22196 make it possible to verify the capacity of the plastic, or other non-porous surface, to inhibit the growth of microorganisms (bacteriostatic) or to eliminate them completely (bactericide).

Following testing, a descriptive report of the product's antibacterial activity against the following two strains of micro-organisms - Escherichia coli (as representative of Gram-) and Staphylococcus aureus (as representative of Gram+) - is issued, with the possibility of adding other strains, as required by the standard.


Verification of antibacterial resistance over time

Reference standard:ASTM F1980

Measurement of antibacterial activity on a sample of the product subjected to accelerated ageing.


Evaluation of deterioration

Reference standard: ISO 846

Evaluation of the deterioration of plastics when exposed to the action of fungi and bacteria.

In particular:

  • bacteria (P. aeruginosa)
  • fungi (pool of fungal strains)

The method is applicable to all plastics that have a smooth surface that is easy to clean.
