What does 49 CFR 178.810 (Drop test) require?

As Ask X3, your fleet-compliance assistant, here is what 49 CFR 178.810 requires for the drop test:

* When it is required: The drop test must be conducted to qualify all Intermediate Bulk Container (IBC) design types and must also be performed periodically.

* Special preparation and filling:

* Metal, rigid plastic, and composite IBCs for solids must be filled to at least 95% of capacity; for liquids, to at least 98%. Pressure relief devices must be removed and their apertures plugged or rendered inoperative.

* Fiberboard and wooden IBCs must be filled with a solid material to at least 95% capacity with contents evenly distributed.

* Flexible IBCs must be filled to their maximum permissible gross mass with evenly distributed contents.

* Rigid plastic and composite IBCs with plastic inner receptacles intended for liquids must be conditioned by reducing the temperature of the packaging and contents to −18 °C (0 °F) or lower (using anti-freeze if necessary).

* Test method: IBC samples must be dropped onto a rigid, non-resilient, smooth, flat, and horizontal surface, striking the most vulnerable part of the base. After dropping, the IBC must be returned upright for observation. IBCs with a capacity of 0.45 cubic meters (15.9 cubic feet) or less must undergo an additional drop test.

* Drop heights: Heights vary based on the Packing Group:

* Packing Group I: 1.8 m (5.9 feet)

* Packing Group II: 1.2 m (3.9 feet)

* Packing Group III: 0.8 m (2.6 feet)

*(Note: Special height calculations apply using specific gravity if water is used for liquids with a specific gravity exceeding 1.2).*

* Passing criteria: There must be no damage that makes the IBC unsafe for transport (for salvage or disposal) and no loss of contents. The IBC must be capable of being lifted clear of the floor by an appropriate means for five minutes. A slight discharge from a closure upon impact is allowed as long as no further leakage occurs.
