Hi again Victor,
Browsing the internet a little deeper, I found several quirky cat videos and then this below regarding hard gold versus soft gold. The video states that hard gold can be plated through an immersion process.

Now, back to the cat videos...

Hi Victor,
The great and all-knowing Wikipedia says hard gold often contains a small amount of cobalt or nickel.
I am also not an expert, but I believe hard gold is an electrolytic process. Although the electrolytic process can be stopped any time, typically target thicknesses are considerably thicker (30 micro-inches or more). If you are looking at 5 micro-inches, I'd guess it is immersion gold. The best action is to ask the supplier. If that's not an option, try EDS looking for cobalt. That's no guarantee, but positive results for cobalt would be informative. 5 micro-inches would be too thin to look for nickel. Good luck.
Did I pass the test?

Fellow TechNetters:
I did not receive a response the FIRST time . therefore I pose the inquiry once again.
“Is there a test or method to determine if gold plating is hard gold or ENIG? XRF will determine thickness of gold but will not verify plating process. I am working with a measurement of 5 micro inches of gold.”
Victor,
