This could provoke a typical A.net screaming match, but I think it's fair to say that the term is most often used to mean flights over about 14 hours. Some purists reserve it only for the very longest flights, over 16 hours, but I don't think that's the most common usage.
FRA-IAH is not ULH, but DXB-IAH is.
The term really came about when the A340-500 and 777-200LR opened up markets that previously couldn't be served nonstop. Previous long-haul equipment such as the 747-400 and 777-200ER had a range of 14+ hours, so the routes above that point became "ULH."
