ISTA 7D is a development of tests to evaluate the effects of external temperature exposures of individual packaged-products. The standard can be used for the development of temperature-controlled transport packages made of any material. It can also be used for individual or comparative performance analysis of standard or insulated transport packages against normally encountered conditions. ISTA 7D is designed to measure the relative ability of a package to protect a product when exposed to test cycles of temperature conditions.

When testing to ISTA 7D, the product and the package are considered together and separately. ISTA 7D is not intended to evaluate the protection afforded packaged-products from shock, vibration and/or compression.

The chart below is from ISTA 7D the standard and provides more guidance on the testing procedure and requirements:
