Input mask

 

Input mask for calculating the required barrier effectiveness of packaging of terminally sterilized products in dependence of changes in temperature, altitude and atmospheric pressure

Change the standard parameters in the grey fields according to your individual conditions. The results in the last section are again computed automatically for each change when leaving the field:

Microbiological challenge to the packaging by transport routes with different altitudes Value: Hint:
Volume of the packaging [cm³] Value > 0
Atmospheric pressure [hPa]
Total of differences in altitudes [m] Value > 0
Total number of air-borne microorganisms in colony forming units [cfu/m³] Value > 0
Microbiological challenge to the packaging by weather dependent atmospheric pressure changes Value: Hint:
Difference of atmospheric pressure change [hPa] Value > 0
Atmospheric pressure [hPa]
Number of atmospheric pressure change Value > 0
Total number of air-borne microorganisms as colony forming units [cfu/m³] Value > 0
Microbiological challenge to the packaging by changes in temperature Value: Hint:
Number of changes in temperature Value > 0
Initial temperature [°C]
Difference of temperature [°C] Value > 0
Total number of air-borne microorganisms as colony forming units [cfu/m³] Value > 0
