UNDERSTANDING Fphy OR EQUIVALENT EXPOSURE TIME AT 121°C
The F0 value of a saturated steam sterilisation process is the lethality expressed in terms of the equivalent time in minutes at a temperature of 121 °C delivered by the process to the load in its container with reference to micro-organisms possessing a theoretical Z-value of 10. ——- Equation 1.0 Lethality rate (L) = 10(T-Tref)/z […]
