“Long-lasting” is a comparison claim that needs defined conditions. Identify whether the product is solid CO₂ or another coolant, then compare complete packouts using the same product limits and exposure. A colder material or larger starting quantity does not establish a longer useful shipping duration.
Ask what the claim actually measures
A duration may describe remaining coolant, container air temperature or product temperature. Ask which endpoint the supplier used. For a shipping decision, the important endpoint is whether the product remains within its specified range throughout the intended exposure.
Also establish whether the advertised “Trockeneisbeutel” contains solid CO₂. Ein Wasser, gel or phase-change pack sold under a similar name cannot inherit CO₂ properties or a different product’s test result.
Build a fair comparison sheet
| Beweis | Frage, die man stellen muss |
|---|---|
| Nutzlast | Does the test represent my dimensions, mass and starting condition? |
| Temperaturgrenzen | Were both warming and overcooling assessed? |
| Vorbereitung | Can our operation reproduce the coolant and container preparation? |
| Belichtung | Does the test cover the intended route, season and delays? |
| Sensoren | Were measurements made at justified product locations? |
| Paket | Were the same model, Schließung, separators and outer components used? |
If candidates were tested under different conditions, do not rank them using only the largest hour value. Request comparable evidence or conduct a defined comparative study.
Compare operating fit as well as duration
Record preparation capacity, coolant availability, Packmaße, Handhabung, carrier acceptance and the receiving procedure. A high-duration configuration can be impractical if the packing line cannot prepare it consistently or the operator does not accept it.
Do not convert the presence of remaining dry ice into a guarantee for every payload size. Any allowed loading variations need supporting evidence and usable packing instructions.

- Keep the accepted component specifications and loading drawing.
- Define permitted payload and route variations.
- Record substitutions in coolant form, container or separators.
- Review significant changes before relying on the old result.
- Investigate failed temperature records against the actual packing and route history.
For applicable US aircraft and water shipments, konsultieren 49 CFR 173.217: Kohlendioxid, solide for gas-release packaging requirements. A successful duration comparison does not itself approve transport.
Häufig gestellte Fragen
Does a colder coolant last longer?
Not necessarily in terms of useful product hold time. Excessive cooling can fail a product’s lower limit.
Can I compare a 48-hour and 72-hour label directly?
Only after confirming the test conditions and endpoints are comparable.
Is reusable coolant always the longer-lasting option?
NEIN. Reuse capability and duration in a specific shipment are separate attributes.
Use evidence to choose the duration
