That seems like a tough question, did you get any answers yet?
 
In my opinion (take it with a grain of salt, sometimes common sense
doesn't count for much in this industry) the lifecycle is most dependant
on thermal cycling, and there is no data for burn-in type studies in
the design specs or acceptance criteria that I know of.
 
Maybe you would have better luck looking for solderability studies
done by the committees, they might have some useful data for you.
 
Good luck,
Jack (the new guy)

Does anyone know what the lifecycle of the boards designed to IPC standards is? Is it stated
anywhere in the documentation?

Thanks Norm
