RMQSI Answers ForumCategory: Reliability ModelsDetermining Accelerated LifeTest Duration
reliability15 asked 9 years ago

What are Reliability professionals using to determine the test time required for an accelerated life test? I’d like to turn-in a time requirement to management.

I have done a mock calculations in my life projection software where I can plug-in numbers for test piece quantity, stress level, and duration. I then plug-in some failure points so a projection can be made. I work with the variables until I get a result that meets our reliability target. From this I can go to management and say I need at least X amount of time.
Is this the best way to do this?????

Known:
