Cold chain is a system
The presence of coolant is not enough. Packaging, route, season, duration and transfer points affect risk. The configuration should be assessed for the actual shipping profile and stated material conditions.
Meaningful monitoring
A logger is positioned to answer the shipping question and has known calibration, range and sampling interval. Start, stop and time zone should allow alignment with the shipment. An indicator without history may provide less information than a complete time series.
Receipt assessment
The recipient checks integrity, monitoring data and documents before releasing material. An excursion is assessed against scientific evidence and a predefined procedure, not solely from the appearance of the package.
LABORATORY APPLICATION
Turning the principle into an auditable record
Before dispatch define acceptable range, maximum duration, packaging configuration, logger position and excursion rule. At receipt record time, integrity, indicator status and the complete temperature record before release. The procedure should also address a missing or failed logger.

COMMON QUESTIONS
Questions specific to this topic
What does a logger establish?
It provides a history at its placement point; representativeness depends on position and packaging qualification.
Does every excursion require rejection?
Not automatically. Temperature, duration, stability and uncertainty require documented assessment.
Why assess by season?
Because external conditions and thermal challenge on the same route change during the year.
