Abstract. Today’s vibration testing standards are intended to simulate the field environments a product, device or package will experience in the real world. Products are tested for a wide range of reasons, from R&D, to production, to life testing. Understanding how a product will react to the real world and the end use environment is critical. It is common practice to collect field data from the end-use environment to verify the testing conditions have accounted for all the real‑world conditions. This paper and presentation will discuss the variety of testing options available for the collected data. This includes playing back the recorded data on a shaker in real time, also referred to as long time-history playback. Other options discussed will be FFT transformation with average and peak-hold methods, the influence of kurtosis on the recorded data, and the proper use of the fatigue damage spectrum to generate a random PSD.
