ABSTRACT:
A repeat insult microbial test method in which an antimicrobial agent is applied to a porous permeable substrate. The porous permeable substrate is inoculated with microorganisms, and the porous permeable substrate is incubated for a predetermined period of time, at a temperature which is conducive to the flourishment of the microorganisms. The porous permeable substrate is reinoculated and reincubated a predetermined plurality of times and the inoculated porous permeable substrate is incubated for a final period of time between 18-24 hours at the temperature used previously. The porous permeable substrate is then examined, and the growth of microorganisms is determined.
