Result Interpretation

Gravity Displacement Autoclave Sterilization Time Estimator calculator computes Sterilization hold time in s using the defined engineering formula and the input values provided. Sterilization hold time is expressed in s. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

Reference D-value at T_ref = 60
Reference temperature = 121
Actual chamber temperature = 121
z-value (temperature coefficient) = 10

Expected Result:

Sterilization hold time = 60

Engineering Interpretation:

Under the given input conditions, the calculated result is: Sterilization hold time = 60 s.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

sterilization hold time = reference d-value at t_ref * pow(10, (reference temperature - actual chamber temperature) / temperature coefficient)
