Cushion Curve Analysis

This test covers a procedure for obtaining dynamic shock cushioning characteristics of packaging materials through acceleration-time data achieved from dropping a falling guided platen assembly

onto a motionless sample. The data acquired may be used for developing a dynamic cushion curve for the specific material being tested. Such data may also be used for comparison among different materials at specific input conditions, or qualifying materials against performance specifications.

A wide variety of different cushion materials, types, and thicknesses can be characterized using a variety of different procedures all described as cushion curve analysis.

In addition to shock absorbing characteristics of cushion materials, Westpak also conducts vibration analysis on cushioning systems and materials using a variety of different test methods, typically the enclosed test lock method as described in ASTM D4168.
