| 26 | An excursion is also not a single class of event. Warming above the labelled range and cooling below it have different mechanisms and are not interchangeable in an assessment, because freezing damage is not governed by the Arrhenius relationship on which the warming arithmetic depends. Guidance for products labelled 2–8 °C accordingly treats a freezing event as a separate category, often with a stricter disposition, and freeze indicators exist precisely because the mean kinetic temperature calculation cannot detect the event.{{r|matthias2007,bhatnagar2007}} | 26 | An excursion is also not a single class of event.

Two vials of chemically identical peptide, one supplied as a licensed medicine and one as a research chemical, may experience the same profile and be subject to entirely different assessments, because only one of them has labelled conditions established by a stability programme.}} | |
