Pharmaceutical cold chain8 / 9

EPS is a good insulator but the box does not set the duration. We work out the ice a 30 mm wall box needs for 24 hours, then look at the three variables that remain.

Match the certificate to device identity, range, uncertainty and traceability; the document alone does not prove fitness for use.

Change triggers revalidation, not the calendar: container, route, coolant, sensor or season. The table shows which change needs which test; the calibration calendar is kept separate.

Validation tests the hardest day, not the average one. The scenario comes from your own shipment records, as the hardest combination that can really occur together.

Choose sensor locations from route mapping and product position; a reading by the coolant or lid may not represent the load.

A transport validation report carries the protocol copy, equipment list, raw data, calibration certificates and deviation reports; the acceptance criteria are written before the test.

Design summer and winter trials around your product, pack and route; one test duration does not fit every shipment.

Was it installed right, does it work right, does it also work on a real shipment: the three stages answer those questions. Below: how many repeats each test needs and which numbers go into the OQ protocol.

Record sensor positions against a body sketch, load and door events. Interpret empty, loaded and seasonal runs separately.

A warehouse at ambient temperature needs at least 7 days of logging, a cold room 24-72 hours, and sensors on a 5-10 metre grid: the numbers behind a mapping study and how its result sets sensor placement.

The field gathers evidence; the assigned decision owner assesses it. Link product, batch and temperature records to the escalation path.

There is no single cold chain certificate: carrier authorisation, equipment conformity and shipment records are separate evidence. The Perishable Food Transport Certificate in the regulation covers only older vehicles without ATP.

Check each veterinary product's authorised storage conditions, route log, and decision owner. Do not assume human-medicine rules apply.

GMP covers manufacture, quality control and batch release; GDP covers purchase, storage, shipment, returns and recall. Production defines the storage temperature; holding it on the road is GDP's job.

Link product identity and movement records to temperature data by shipment ID to identify affected stock during an excursion.

Before treating an announcement as a new obligation, check its date, scope and later updates, then review the relevant procedure.
