• b. The drop height shall be determined for the required horizontal impact velocity based on the transfer of potential to kinetic energy (h = v²/2g). Unless otherwise specified, the vertical height is a drop of 23 cm (9 in.) that results in a velocity of 2.13m/sec (7 ft/sec) at impact.
• c. Load the test item (container) with the interior packing and the actual contents for which it was designed. If use of the actual contents is not practical, a dummy load may be substituted to simulate such contents in weight, shape, and position in the container. Block and brace the contents, or dummy load, and cushion them in place as for shipment. When the pendulum impact test is performed to evaluate the protection provided for the contents, the rigidity of a dummy load should closely approximate that of the actual contents for which the pack was designed.
