ISTA 7E & Standard 20

ISTA 7E is a simulation test that evaluates the effects of external temperature exposures for packaged products transported in a small parcel environment. This procedure is used for general testing and in the qualification of insulated shipping containers. Purple Diamond Testing offers ISTA 7E Testing as part of our cold chain testing and validation services. The objective of this test is to ensure that the packaging meets the minimum performance requirements for maintaining the product within the desired temperature range from the time of packaging until it reaches its destination.

The test evaluates the packaging’s ability to protect the product from temperature excursions that may result from varying temperature and humidity conditions during transport. The test method involves subjecting the packaging to a predetermined temperature profile that simulates the expected temperature fluctuations during the shipping cycle. The package is then evaluated for its ability to maintain the desired temperature range of the product inside. This test can be useful for companies that ship perishable goods such as food, pharmaceuticals, and medical supplies. It assures that the products will arrive at their destination safely and in good condition, reducing the risk of spoilage or damage, and protecting brand reputation.

The ISTA 7E thermal transport packaging standard has been developed to ensure consistent and reliable performance of insulated shipping containers, so that professionals in the industry can trust their products will remain within the necessary temperature range, and delivered safely to their customers.
