UN Testing Information
We offer a number of UN-Rated packaging kits to meet your needs. Our kits have been tested by our DOT-certified testing partner, TEN-E. Here's an overview of the required tests packages must pass:
- 5 packages are prepared exactly as they would be for transportation.
- The testing lab will use water in place of the hazardous material and place additives in the water to vary the specific gravity to match what is actually being shipped.
- Each package is then dropped from a specific height, determined by the Packing Group of what is being shipped. Any breakage or leaking voids the package.
1 Drop for every prepared sample (5 total).
- Top Side
- Bottom Side
- Short Side
- Long Side
- These are done by stacking packages on each other to make sure they are strong enough that they won’t collapse.
- These are done to simulate the package traveling by motorized vehicle (boat, plane, train, truck).
Cobb Water Absorption
- This is done on the actual fiberboard box to make sure the paper used is of high enough quality and that it won’t disintegrate with moisture.
- This is done for Air Transport Only when the primary inner container will contain liquid.
- Due to pressure variation when traveling by air, this is done to show the container won’t leak.
Once a package has been able to successfully pass all of the tests above, it will then be UN approved and be permanently marked or embossed with a UN marking.
New tests are performed on new packages and when any design changes occur in an existing package. Once a package is tested, it must go through a periodic retest. Combination Packaging must be retested every 24 months. Single Packaging (pails, drums, etc.) must have a periodic retest at least every 12 months.
