When should temperature testing be done to 7D versus 7E?
We are planning to test product shipped in thermal containers (cold chain) as well as some shipped in standard corrugated shipping containers. We will be evaluating the ability for the packages to maintain acceptable temperature ranges on products that could be both cold and heat sensitive. The specifications of 7D seem to provide the hot and cold extremes that could be encountered in both bulk and unit shipment but the the standard refers to 7E when using thermal containers. However, the 7E standard no longer looks like a defined air shipment configuration (tarmack, flight, tarmack). So what is 7E simulating and when is it appropriate to use 7E instead of 7D?
ISTA, in cooperation with the Pharmaceutical Cold Chain Interest Group (PCCIG), completed an extensive survey of temperature ranges found in the U.S. parcel delivery distribution environment. This data
was used to develop ISTA 7E , Testing Standard for Thermal Transport Packaging Used in Parcel Delivery System Shipment, which should be considered for use in lieu of Procedure 7D. 7E is not available in the Resource Book but is available for a separate purchase from ISTA. Full details on ISTA 7E can be found on the ISTA website:
