Oh.  I thought you were building something from new parts.
If you want assurance that the part will last for some particular time, 
you could always replace it with some known part.  But remember that you 
will also need to be able to measure the operating current (and 
temperature can also be a big issue in high-power applications).

What exactly are you trying to do?
