Drop Test Video

DROP TEST VIDEO COMPARING DROP PADS

Container Products Corporation designs and manufacturers containers for the transportation and storage of radioactive material, observing strict United States and International Atomic Energy Agency guidelines and safety standards. CPC’s container designs are built to pass stringent Type A standards, and a rigorous testing process is required for certification and design approval.

There are four tests needed to achieve a Type A certification. First, the Water Spray Test, which proves the container to be water tight, is conducted.

Test two looks at the container’s ability to withstand penetration by a steel bar.

Test three evaluates the container’s ability to endure crushing pressure by placing a load of a specific mass on the container for a 24-hour period.

The most abusive of the tests is the fourth and final one, the Drop Test. A container is loaded to it’s maximum gross weight – in this case, 8,000 pounds – so that the center of mass is directly over the impact point in order to deliver maximum damage and dropped from a height of 48 inches onto a horizontal surface of such mass and rigidity as to cause the full impact force to be absorbed by the container rather than the drop surface.

The CPC-engineered drop pad is a steel-reinforced concrete block with a thick steel plate attached to the top surface. The unit is then form cast into the ground. For comparison- a steel plate laid on an asphalt parking lot – was used.

As the video shows, on CPC’s engineered drop pad, all of the force is absorbed by the container; where in the video using the steel plate over asphalt you will see that it jumps with the container’s impact, showing how much of the force is transferred through the plate and into the asphalt.

In looking at the drops at the point of impact you can see that the container dropped on CPC’s engineered pad shows a substantial amount of material breeching containment, where on the container dropped on the steel plate does not show this failure. results, the impact corners underwent significantly different levels of damage. The container dropped on CPC’s engineered pad absorbed the full impact, and, as a result, was deformed to a far greater extent than the container dropped onto the steel plate laid over asphalt.

Compliance with federal and international regulations is mandatory for the safe transport and storage of radioactive materials. This is why Container Products Corporation conducts their certification tests to a higher standard, using a drop pad that will give evaluators and engineers a true picture of the integrity of their fabrication and design.
