A specification starts with the component, because red cells, platelets and fresh frozen plasma travel in three separate temperature regimes and one carrier cannot suit all three. The Turkish Ministry of Health's National Blood and Blood Components Guide (2016) requires components to travel in a validated system that holds the intended duration and temperature (section 6.1.6); every clause follows from that sentence.

ClauseWhat the specification statesGuide
Red cellsEquipment at +2/+6 °C; at most 10 °C at the end of a 24-hour journey, never below 1 °C at delivery6.1.6.2-6.1.6.3
Platelets20-24 °C, not chilled; transport without agitation no longer than 24 hours6.3.2
Fresh frozen plasmaFrozen, as close as possible to storage temperature (-18 °C or below)6.1.6.5, 6.4.1
CoolantCooling packs not in close contact with bags; divider is part of the carrier6.1.6.1
ContainerWell insulated, easy to clean and use6.1.6.1
MonitoringTemperature indicator; at delivery a thermometer between two bags for 5 minutes, or a surface reader6.1.6.2

The acceptance criterion is written in three parts: range, duration and outside temperature. 'Stays within range' cannot be audited without how many hours and in what ambient, so a short in-hospital transfer and an intercity transport go into separate clauses. Validation runs on the institution's longest route in the warm season, and its records are attached to the specification.
