ISTA Series 6: 6-FEDEX-A Testing vs. Standard UN Testing

When we think of UN Testing, several things may come to mind. We have the drop test which evaluates the package’s ability to handle collisions, the vibration test which simulates movements created by a motorized vehicle, the Cobb test which is designed to ensure the fiberboard will not disintegrate when exposed to water, and the stacking test which checks the integrity of the package by stacking various weights over the top of it. However, those that want to test their packages under the ISTA 6-FEDEX-A requirements for packages 150 lbs. or under are finding it to be difficult to get a passing grade.

What Are The Differences?

Under standard testing, each sample is dropped only one time at a specific height for a total of 5 drops total from 5 different samples.

Under the ISTA 6-FEDEX-A testing, 1 complete sample is dropped 10 times focusing on every corner and edge of the package. Any significant leaking on either of these tests would result in a failure, which makes the ISTA testing very difficult to pass because of the number of drops. In addition, flat and elongated packages must go through a bridge or concentrated impact test procedure. This procedure consists of dropping a wooden box measuring 12″ x 12″ x 12″ dense wooden box weighing 21 lbs. on the midpoint of the package.

Under standard testing, the stacking Continue Reading…
