Centre de charge utile
Shows the response of the protected product mass and helps compare overall hold behavior between layouts.
Packout engineering and test planning
Conception et test de packout chaîne du froid pour conditions réelles
Define the product limits, pression de route, isolation, disposition du liquide de refroidissement, positions des enregistreurs, environmental challenge, and acceptance criteria before a packout becomes a repeatable shipping instruction.
Acceptance criteria firstDefine what temperature and arrival condition must be protected.

Include in the test scope
Define the system
Six paramètres contrôlent le test de packout
Changing one input can change the temperature curve, so the test brief should identify all six before results are compared.
1
Limites de produit
Plage cible, excursion allowance, sensibilité au gel, et conditions d'arrivée.
2
Charge utile
Masse, dimensions, thermal properties, température de départ, and fill pattern.
3
voie
Temps de transit, demeurer, saison, transferts, transporteur, douane, et retard de réception.
4
Isolation
Volume utilisable, structure du mur, fermeture, ajustement de la doublure, et entrefers.
5
Source froide
Type de liquide de refroidissement, masse, conditionnement, placement, séparation, and remaining state.
6
Preuve
Carte de l'enregistreur, profil de test, critères d'acceptation, arrival checks, and report scope.
Measure more than one location
Placer les loggers là où réchauffement et sur-refroidissement peuvent apparaître
A center logger alone may miss a hot edge or a cold-contact point. Final positions depend on the payload geometry, disposition du liquide de refroidissement, and acceptance plan.
Payload chamber
EnregistreurLiquide de refroidissement
Cold-contact risk
Place a logger near the payload surface closest to conditioned or frozen coolant when freezing or cold shock is a concern.
Warm edge or corner
Monitor an exposed wall, couvercle, seam, or air gap where ambient heat may reach the payload first.
From requirement to repeatable packout
Utiliser une séquence de test qui conserve les hypothèses
Test results are meaningful only when payload, conditionnement, ordre d'emballage, défi ambiant, and acceptance rules are recorded together.
Phase 1
Définir l'acceptation
Record product limits, allowable excursion, durée de l'itinéraire, arrival checks, and responsible approval team.
Phase 2
Construire les configurations candidates
Choisir l'isolation, masse de liquide de refroidissement, conditionnement, séparateurs, disposition de la charge utile, fermeture, et carte de l'enregistreur.
Phase 3
Apply challenge
Use an agreed ambient profile or controlled route trial that reflects the intended lane and season.
Phase 4
Revoir les preuves
Compare temperature traces, hot and cold spots, humidité, fuite, état du carton, and receiving quality.
Phase 5
Verrouiller et surveiller
Issue packing instructions, spécifications des composants, training checks, report references, and re-test triggers.
Review the complete result
Ce que le rapport de test doit montrer
The temperature curve is important, but it should remain connected to the exact packout and its physical condition after the test.
| Enregistrer | Que capturer | Pourquoi ça compte |
|---|---|---|
| Configuration | Expéditeur, dimensions intérieures, charge utile, coolant type and mass, séparation, fermeture, et ordre d'emballage. | Allows the tested setup to be rebuilt without guessing. |
| Conditionnement | Température de démarrage de la charge utile, conditionnement du liquide de refroidissement, freezer or staging time, and packing start time. | Separates component performance from preparation errors. |
| Carte de l'enregistreur | Logger IDs, calibration status where required, exact positions, recording interval, and ambient logger. | Explains which location each curve represents. |
| Temperature result | Temps dans la plage, minimum and maximum, excursion timing, edge and center differences, and remaining margin. | Connects the trace to the agreed acceptance criteria. |
| Physical condition | Fuite, condensation, wet-out, résistance du carton, mouvement du produit, scellés, étiquettes, et le liquide de refroidissement restant. | Checks whether the packout arrives usable, not merely cold. |
| Décision | Approved scope, limites, required adjustment, repeat test, essai routier, and change-control triggers. | Prevents a screening result from being treated as universal approval. |
Match the evidence to the risk
Choisir le bon niveau de test
Design screening
Use when comparing shipper sizes, masse de liquide de refroidissement, placement, or separation before the final design is selected.
- Relative comparison
- Fast layout refinement
- Not final lane approval
Documented packout test
Use when the complete configuration needs defined acceptance criteria, preuve d'enregistreur, instructions d'emballage, and a controlled report.
- Recorded assumptions
- Defined ambient challenge
- Repeatable configuration
Programme route ou qualification
Use for high-value, réglementé, saisonnier, exporter, or business-critical lanes where the buyer’s QA team defines formal protocol and approval requirements.
- QA-owned acceptance
- Agreed protocol and repetitions
- Change and re-test control
Protect the approved configuration
Revoir ou retester lorsque les hypothèses importantes changent
Packaging change
Different insulation, épaisseur de paroi, dimensions, fermeture, carton, doublure, or internal air space.
Coolant change
Different formulation, masse, taille, conditionnement, quantité, placement, or separator thickness.
Payload change
Different product, masse thermique, niveau de remplissage, température de départ, pack primaire, or sensitivity.
Lane change
Durée plus longue, transporteur, saison, destination, jambe aérienne, les douanes habitent, remettre, ou processus de réception.

Questions before testing
Cold chain packout design and testing FAQ
Is a screening test the same as formal qualification?
Non. Screening compares design directions. Formal qualification requires an agreed protocol, critères d'acceptation, controlled methods, documented repetitions where applicable, and approval by the responsible quality team.
Should we test the insulation or the complete packout?
Test the complete configuration that will be used: charge utile, température de départ, expéditeur, liquide de refroidissement, conditionnement, séparation, fermeture, carte de l'enregistreur, défi ambiant, et séquence d'emballage.
How many temperature loggers are needed?
The number depends on packout size, géométrie de la charge utile, placement du liquide de refroidissement, expected hot and cold spots, and protocol requirements. A center, cold-contact, warm-edge, and ambient position may be considered for early design work.
Can a test guarantee every future shipment?
Non. Results apply to the recorded assumptions and test scope. Changes in product, conditionnement, liquide de refroidissement, itinéraire, saison, transporteur, or operating process may require review or re-testing.
Can simulated payload be used?
It may be used during development if its mass and thermal behavior are suitable for the comparison. The final test scope should state what was used and whether actual product testing is required.
What information should we send first?
Send the product temperature limits, sensibilité, payload dimensions and mass, durée de l'itinéraire, saison, transferts, shipper options, hypothèses sur le liquide de refroidissement, besoins de surveillance, and expected report or approval level.
Prêt à transformer un profil d’expédition en plan de test packout ?
Share the payload, plage de température requise, durée de l'itinéraire, défi ambiant, famille d'emballage, hypothèses sur le liquide de refroidissement, et les besoins en preuves. Tempk can review the practical starting scope before samples are prepared.
