Abstract:
1. A method for testing a gas permeable sterilization packaging unit formed wholly of gas permeable material or having at least one gas permeable component, the packaging unit being provided for sterilization of objects to be sterilized for its efficacy against microbial recontamination of the objects after they have been sterilized, the method comprising: Charging the gas permeable packaging unit with a non-liquid nutrient medium being open to settlement of microbes; Sterilizing the gas permeable packaging unit; Storing the gas permeable packaging unit for a period of time under ambient conditions; Placing the gas permeable packaging unit in an incubator or incubation chamber; Incubating the gas permeable packaging unit in the incubator or incubation chamber to promote multiplication of microbes expected to be present, by subjecting the gas permeable packaging unit over a preset period of time to a temperature and a gas atmosphere each being favorable for the multiplication of said microbes, in order to cultivate said microbes in case those would be present in or on the nutrient medium due to recontamination after sterilization; and Observing if microbes multiplied in or on the nutrient medium.
