ASTM D3103: Standard Test Method for Thermal Insulation Performance of Distribution Packages
ASTM D3103 is a test method intended to evaluate the performance of thermal insulated packaging for high-value, high risk materials. This test can also be used for products that require accurate internal package temperature readings while being exposed to various external air temperatures. Certain products, like biological materials, pharmaceuticals, and blood products, must be shipped inside temperature regulated packages.
Because of the many ways the performance of a thermally insulated package can be affected, testing should be conducted with the actual packaging that will be used during distribution of the product.
