Determination of Germ Proofness with Air Permeance* The determination was performed according to DIN , subclause 4. Each after sterilization by stem((34 ), ethylene oxide and H 2O 2-plasma the sample material was contaminated with the test germ on both sides. Result: Sterilization-Test side Number of CFU/specimen Σ Ethylene oxide-side A: 4 -side A: 2 4 CFU=colony forming unit 2.2 Determination of Germ Proofness under Humidity* The determination was performed according to DIN , subclause 3. Each after sterilization by steam (34 ), ethylene oxide and H2O2-plasma the sample material was contaminated with the test germ on both sides. Result: Sterilization-Test side Number of CFU/agar plate Σ Ethylene oxide-side A: -side A: CFU=Colony forming unit According to DIN , section 3.7.3,a re-examination had to be performed on side A of the material sterilized by due to a total number of CFU between and 5.
