Appendix C to Part 173 - Procedure for Base-level Vibration Testing
Base-level vibration testing shall be conducted as follows:
1. Three sample packagings, selected at random, must be filled
and closed as for shipment. A non-hazardous material may be used in
place of the hazardous material if it has essentially the same
physical characteristics.
2. The three packages must be placed on a vibrating platform
that has a vertical double-amplitude (peak-to-peak displacement) of
one inch. 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.
3. The test must be performed continuously for one hour at a
frequency that causes each 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.
4. Immediately following the period of vibration, each package
shall be removed from the platform, turned on its side and observed
for any evidence of leakage.
5. Rupture or leakage from any of the packages constitutes
failure of the test.
