FH value of Dry Heat Sterilization

Fh value calculation

please take a look at this :
’ Using the accumulated Fh value for the coldest and hottest locations calculated during each run, calculate for each vial size the minimum and maximum AFh value using the student parameters in attached table to represent a 95% confidence limit for the depyrogenation cycle. (Fh=(10^((T-TB)/Z)*(60/60)) with base temperature TB=250C, D250C = 4.99 minutes and Z=46.4C).’
