Standard Test Method for Determining the Activity of Incorporated Antimicrobial Agent(s) In Polymeric or Hydrophobic Materials

Importancia y uso:

5.1 This method can be used to evaluate effectiveness of incorporated/bound antimicrobials in hydrophobic materials such as plastics, epoxy resins, as well as other hard surfaces.

5.2 The aqueous based bacterial inoculum remains in close, uniform contact in a “pseudo-biofilm” state with the treated material. The percent reduction in the surviving populations of challenge bacterial cells at 24 h versus those recovered from a non-treated control is determined.

5.3 The hydrophobic substrate may be repeatedly tested over time for assessment of persistent antimicrobial activity.
