The ASTM D1596 standard test method is used to evaluate the dynamic shock absorption properties of Encasement materials. Acceleration time data is obtained by dropping the guide platen from a certain height onto a stationary sample. These data can help to understand the dynamic cushioning performance of Encasement materials, but do not include the effects of external Encasement components. Test results can be used to compare the shock absorption of different materials, but caution is required when predicting Encasement performance, as data correlations may vary depending on materials and test methods. The standard does not cover all safety issues, and users need to develop appropriate safety and health measures.
