A standard 20 amp breaker should handle a 40 amp 'inrush' of any equipment listed to operate on a 20 amp circuit.

If you are talking "inrush" from an inductive load like a motor, I would expect a 20 amp breaker to have no problem holding a 40 amp inrush.
I don't know the trip curves but I would think a 20 amp breaker would hold at 40 amps for at least a minute or two, so an "inrush" for just 1 second or less should hold.

UL testing is for a 200% overload to be held for 2 minutes.
