1. A method for testing the quality and/or the reliability of a component, comprising:

  • applying test conditions to a plurality of specimens of the component;

    while applying the test conditions, measuring the same variable from each of the plurality of specimens;

    computing a running average of the measured variable across the plurality of specimens;

    computing residuals between the measured variable for each specimen and the running average;

    determining from the residuals whether the associated specimens are degraded;

    recording the time at which the specimen of the component was determined to have degraded; and

    determining how many test events have been repeated on the specimen of the component when the specimen of the component was determined to have degraded.
