A standardized piezoelectric polymer (PVDF) shock-wave stress gauge has been developed in cooperation between Sandia and the Institute Saint Louis, France. The shock response of these gauges is established from controlled shock-loading experiments in which impact-induced current pulses are measured with high speed digitizers. This report documents the preparation and assembly of PVDF gauges to be used in these controlled shock-loading experiments, and a computer program ''PVDF-AUTO'' written for analysis of the data obtained in such experiments. Due to digitizer noise before and after actual gauge output, it is often difficult to distinguish the data points at which the loading pulse begins, ends, and the unloading pulse arrives. It is the purpose of this data analysis program to identify these points in an objective manner that is mathematically documented and free from human judgement, thus analyzing data consistently regardless of experimental conditions.
