Hi,
I would like to demonstrate an MTBF of 50,000 hours using accelerated life testing. I’m not able to determine how many units, how much time i should test to validate my MTBF and what type of stress i should apply (i would prefer applying single stress rather than multiple stresses). As the cost of testing increases with the no.of units and the test time, i would like to have a plan which is cost effective as well as meets my MTBF requirement.
Also i wanted to know how i will determine that, the number of test units (sample size) and the duration of the test in the correct one to demonstrate/validate an MTBF value of 50,000 hours.
Looking for your suggestions.
