There is some data on this page:

I have used the RTD140xx series Schrack/Tyco for years in primarily RTTY 
contesting duty at the KW power level - all without fail.  But I have not 
conducted BDV testing on those relays.

Thanks for an excellent exposition of the issues. Now how about the
other half of the question -- part numbers for relays that meet the
need? This reflector (and the spirit of ham radio) is about SHARING
information.
