Hi Paul & All,
It is proper to use different names— Reliability Testing vs. Survivability 
Testing, for these tests, because they do not test the same thing, even if the 
failure modes observed are the same. The loading conditions and the material 
responses to them are not.
To say: " One effect is to increase testing throughput by a factor of ~10:1 
if the product is robust and survives to end of test. Weak product fails in 
just minutes which in effect increased through put by a factor of ~40:1." is 
correct in terms of the through-put but not in terms what is measured. 
That is a problem with all those 'highly accelerated' tests, they do 
accelerate the time to failure, but they do not typically accelerate the pertinent 
damage mechanism.
So, lets keep the two tests, Reliability Testing and Survivability Testing, 
separate, because each serves a very useful function.
