What are tv-5 relay contacts?

This explanation was found on a OMRON newsletter:

Typically, a relay being tested for UL TV Rating sees an Inrush Load 10 times that of steady state current at 120VAC.

For example, a relay receiving TV-3 Rating sees approx. 30A Inrush for a very short duration at 120VAC and settles to a steady state current of 3A, 120VAC before cycling off. Relays must operate successfully for 25,000 cycles of TV Load Testing to receive a UL TV Rating.
