Learn how to calculate the D - Value, Z - Value and F0 - Value for Sterilization.
D-Value (Decimal Reduction Value) :It is time required at temperature T to reduce a specific microbial population by 90% or by a factor of 10.
Z-Value :Z-Value is the number of degrees of temperature change necessary to change the D-Value by a Factor of 10.
Sterility Assurance Level (SAL) :SAL of a Sterilization process is the degree of assurance with which the process in question renders a population of items sterile.
