ASTM-D4728

Shipping containers are exposed to complex dynamic stresses throughout the distribution cycle. Approximating actual damage, or lack of damage, experienced in real life may require subjecting the container and its contents to random vibration tests.

Vibration can impact the shipping container, its interior packing, means of closure, and contents. The random vibration test allows analysis of the interaction between these components and should be based on representative field data. When possible, confidence levels may be improved by comparing laboratory test results with actual field shipment effects.

Design modification to one or all of these components may be used to achieve optimum performance in the shipping environment. Random vibration tests may be simultaneously performed with transient or periodic data to simulate known stresses of this type, such as rail joints, pot holes, etc. Random vibration may be conducted in any axis (vertical or horizontal) or in any package orientation. However, different test levels may be utilized for each axis depending on the field environment that is to be simulated.
