I know this was not the case at TopTen.  George, W2VJN described the 
testing process he used to make sure the relays they use can do the 
job.  IIRC, it included extended key-down tests as maximum legal power and 
more, into a relatively high SWR.  You can probably find his message fairly 
easily if you search the archive of this list for his callsign and simply 
the word relay.
