What F₀ means: equivalent time at 121.1 °C with z-value of 10 °C
Free material · Thermal qualification
In thermal qualification, correct temperature does not prove sterilization
Execution guide to ISO 17665. The thermocouple can log 134 °C for the declared time and the load may still not be sterile, because moist heat depends on steam contact with every surface, and residual air blocks that contact.

“The technical basis connects what f₀ means: equivalent time at 121.1 °c with z-value of 10 °c with where sensors go, and why the cold point is inside the pack, so the material supports an auditable decision instead of a generic checklist.”
