Stability & Storage · Excursion Assessment
Estimates the loss of labeled shelf life caused by a short, out-of-range temperature exposure, using an accelerated-stability degradation rate.
From the accelerated stability study at the relevant elevated condition.
Duration is converted to days (÷24) for the calculation.
loss/day = (loss % ÷ period days) → loss during excursion = loss/day × excursion days → shelf-life loss = (shelf life ÷ spec range) × loss during excursion.
