Which thermal qualification reference documents were selected for the comparison?
Among the different reference documents, we have selected only those which have a thermal efficiency qualification method for insulated boxes, i.e. the following reference documents:
- French standard NF S99-700
- American standard ASTM D3103-07
- German standard DIN 55545-1:2006-03
- ISTA 5B Guide combined with ISTA Procedure 7D and the ISTA 7E standard
- WHO Guidelines WHO/IVB/05.23. We have selected this guide because it proposes temperature profiles as well as the number and positioning of sensors.

Analysis and conclusion: NF S99-700, the most comprehensive reference document
Only the reference documents NF S99-700, ASTM D3103-07 and DIN 55545-1:2006-03 are produced by official standardisation bodies and have the status of norms. Both the NF and ASTM norms allow thermal qualification of temperature controlled packaging to be achieved.
Nevertheless, the NF S99-700 standard is the most comprehensive because it puts forward:
- two packaging qualification protocols (a standard protocol and a specific protocol),
- one standard test product,
- 21 temperature profiles from 1 to 96 hours all year-round,
- number and positioning of sensors.
As for the DIN standard it does not permit qualification which guarantees a sufficient level of safety.
With regard to the ISTA 5B guide, the ISTA 7D procedure and the ISTA standard, these reference documents do not have the status of a norm. All of these documents are supplementary: their combination (fusion) in a single protocol or with the ASTM D3103-07 standard allows in effect thermal qualification to be achieved.
Lastly, the tests proposed by the WHO Guidelines (WHO/IVB/05.23) represent stress tests and do not represent the conditions of an actual logistical circuit. It can be supplementary to another reference document but on its own, it does not allow significant thermal qualification to be achieved. Only the (AFNOR) NF S99-700 standard requires measured uncertainties in the declared conformity to be taken into consideration.
