An inspection looks at how the conclusion was reached, not at the conclusion itself, so the report carries enough records for another team to follow and repeat the test. According to the WHO supplement on qualification of insulated shipping containers, the performance qualification report summarises the test data and performance characteristics and bases its conclusions on them.
- Protocol: a copy with signature log; purpose, scope, responsibilities and acceptance criteria (product temperature range and minimum transport duration).
- Setup: equipment and material list, pack layout, sensor locations, photographs or drawings where needed.
- Data: test graphs, worksheets, all raw data.
- Devices: calibration certificates.
- Deviations: a record of each departure from the protocol.
WHO expects a data logger accurate to ±0.5 °C with 0.1 °C resolution and a recording interval of at most 30 minutes; 5 or 10 minutes is better. Every deviation from the protocol goes into a deviation report.
The decision is conditional. WHO asks for at least three tests per container at both minimum and maximum load for each packaging configuration, with a series in the warmest and the coolest part of the year. Re-qualification is considered when components, route or transit time change, so end the report with the load range, temperature profile and duration written as an instruction that can be read on the floor.
