ASTM vs. ISTA testing at Westpak

ASTM International and the International Safe Transit Association (ISTA) have created thousands of testing standards for many industries; Westpak's testing is focused on products and packaging and uses just a few. Some protocols document test processes and parameters for package systems, enabling labs to simulate in-transit environments that a product and packaging system will likely encounter.

Compliance with more than one test standard may be required depending on the product, its distribution and storage cycle, and regulatory guidelines for its industry. For example, a pharmaceutical container may require testing for breakage, a child-proof enclosure, leak, cold chain, label abrasion, etc. Also, achieving package compliance with testing standards like the ISTA 3 Series may be required by couriers to qualify for transit; Amazon requires vendor package certification to the ISTA 6 Series protocols.

The most notable difference between ISTA and ASTM testing standards is how they’re presented. The ASTM packaging testing standards are detailed in the official literature, but the levels, sequences, and orientations are left to the discretion of the test operator. ISTA testing protocols, on the other hand, are meant to adapt to unique package-related conditions or configurations, with each testing procedure containing thorough step-by-step instructions, including levels, sequences, and orientations, that must be strictly followed.

How do I determine whether I need ASTM or ISTA testing?

Determining whether you need ISTA or ASTM testing ultimately depends on the type of product or packaging system being tested, as well as its transit and distribution method. If the object is being sent via FedEx or UPS, for example, this may influence your decision. Likewise, if your test sample is only being transported on the East Coast, you may benefit from a different testing series than a sample that will be distributed cross-country.
