Hardware reliability Test
I see this as a statistical modelling issue. You need to determine what the real-world requirement is before attempting any kind of accelerated ageing testing. Then you need to determine the risk you are willing to take in relying on your testing. Testing one example of a component (sample size, N = 1) has absolutely no predictive value whatever.  There are plenty of reference texts available to help you with sampling and accelerated testing. Tighten up your specification. Do the reading. Then come back here.
