Signatrol F₀ Academy

1. Temperature vs Time

Warm-up phase

2. Lethal Rate

L = 10^{((T − Tref) / z)}

3. Accumulated F₀

Sum of lethal-rate contributions over time

Current calculation

L = 10^{((T − Tref) / z)}

T = 25.00°C

Tref = 121.1°C, z = 10°C

L = 0.0000

ΔF₀ = L × Δt

ΔF₀ = 0.000000 min

Cooling

During early heating, the lethality contribution is extremely small because the temperature is well below the reference temperature.

F₀ is not simply the time spent at 121.1°C. It is the accumulated equivalent exposure at the chosen reference temperature.
