• All packaging design types used in transportation must meet the vibration standard.

Each packaging must be capable of withstanding, without rupture or leakage, this vibration test procedure:

1. Select three sample packagings at random that are filled and closed as for shipment.
2. Place them on a vibrating platform that has a vertical or rotary double-amplitude (peak-to-peak displacement) of one inch.
3. Note: The packages should be constrained horizontally to prevent them from falling off the platform, but must be left free to move vertically, bounce and rotate.
4. Perform the test for one hour at a frequency that causes the package to be raised from the vibrating platform to such a degree that a piece of material of approximately 1.6 mm (0.063 inch) thickness (such as steel strapping or paperboard) can be passed between the bottom of any package and the platform.
5. Immediately after the vibration period, remove each package from the platform, turn it on its side and look for any evidence of leakage.

Other equally effective methods can be used if approved by the Associate Administrator for Hazardous Materials Safety.

Passing the test

A packaging passes the vibration test if there is no rupture or leakage from any of the packages. No test sample should show any deterioration that could adversely affect transportation safety or any distortion liable to reduce packaging strength.
