IPC-4552: Specification for Electroless Nickel/Immersion Gold (ENIG) Plating for Printed Circuit Boards.

Dear Friend,
Did IPC indicate that immersion gold thickness have to be minimum 2u" gold? This 2u" thickness is referring to the gold thickness only or it is the total thickness which includes the nickel too? Which IPC documents indicates this?
Hope to have your expertise advise.
Thanks & Best Regards
