Analyzing Accelerated Test Data with Unrelated Failures
When running an accelerated test, it may be assumed that the test equipment is going to operate properly when it is requested to do so. In reality, though, the test equipment will more than likely fail over a certain period of time (just like the units being tested) and may need to be repaired or replaced. But what happens if the test equipment actually fails during the test? What do you do then? How do you treat the units that were unable to complete the test in the analysis? One possible solution would be to simply remove the units from the analysis since they did not actually complete the test. However, valuable information may be lost by not including these units. If you do include the units in the analysis, should they be considered failures or suspensions? How you answer these questions will play an important role in your analysis of accelerated test data.
