I'm sure we all agree that NO failures is the goal, but to John's point, I 
think it would be instructive for some to know what types of failures are 
generally found.   (e.g.  marking, ventilation openings, temperature limits, 
dielectric strength, ground bonding, critical components, clause 
misinterpretation, etc)

 

 

I remember a ground test failure of a printed wiring board.  I examined the 
failed board, and found that the current path that was tested was not where 
ground current would flow.  I pointed this out and the correct path.  They 
repeated the test on the correct path and the construction passed.  

 

There was a delay, but we were able to recover.
