Eddy Current probes are used for the testing of steam generator tubing integrity in nuclear power plants. Their use environment is far more severe than the distribution environment, which includes truck and airplane delivery of small parcels. As each probe has soldered connections susceptible to damage this study was undertaken to investigate a possible influence of vibrations due to transport to a probe lifetime. A sweep vibration test was performed on a product with no packaging. It proved that the probe was able to vibrate in different ways unless restricted by the package. With the packaging solution defined in more detail a sample of 10 probes was exposed to random vibrations on a shaker table. Later these probes were tested for lifetime together with the sample of 10 virgin probes. Results were analyzed for statistical significance and the statistics proved the influence of vibrations to the probe lifetime. Finally, the laboratory testing results were compared with the probe lifetime data obtained during a real steam generator inspection.
