Performance tests
Customized isothermal packaging tested and validated

Test the performance of isothermal packaging to determine how long it can maintain the desired temperature within the stability range of the heat-sensitive product being transported.

What is the purpose of a performance test?

A test in a climatic chamber validates the performance of a stand-alone isothermal solution under given conditions.
It ensures that the solution is correctly sized: the choice of material thickness, the number of cold accumulators, depending on the desired temperature inside the packaging, and the shipping season (summer, winter outside temperature, etc.).

A test in a climatic chamber can also give an answer on an existing packaging:

  • Does it perform well for the way I use it?
  • If I add a cold accumulator, can I last 12 hours longer?
  • Will putting a different product inside my packaging change its performance?
  • Can it meet a specific need with an outside temperature different from the usual transport plan?

What are the steps involved in validating a package?

Definition of
test protocol

We work with you to determine your needs: which product is to be tested, under what conditions? summer or winter shipment? storage and handling conditions for cold accumulators. Isovation draws up a test protocol.

Carrying out
the test

Theoretical testing with our simulation tools, or real-life testing in our climatic chambers: two possible options.

The deliverable:
the validation report

Validation report: proof of the performance of your isothermal packaging. This document states what has been tested, and the conditions under which the test was carried out. Isovation delivers a validation report with data recording.

Isovation is equipped with a test laboratory capable of testing and validating stand-alone isothermal solutions.

The climatic chamber test reproduces exactly what happens when your isothermal package is shipped. We place recording probes inside your products, and vary the temperature outside the packaging. Our climatic chambers reproduce the outside environment by varying temperature and simulating seasonal variations. At the end of 24, 48, 72, 96 or more hours, we draw up a validation report. If the product temperature has remained within the desired range, the solution is validated.

PT100 temperature probes are calibrated annually on the UKAS measurement chain.

Our climatic chambers meet the requirements of NFX 15 140: a standard relating to climatic chambers, their characterization and verification.
Your packaging is validated to NF S99 700 or another standard (ISTA / customer specification).

Tell us what you need, and we’ll tell you whether your packaging performs well, or suggest a stand-alone isothermal pack from our range of validated packaging.
