No, that information belongs on the SCD for the component.
There are so many different applications with different requirements so there is no standard that could cover them all.
Even PWBs plated with gold must have the exact dimensions/methods documented on the fabrication drawing if they are outside of the ENIG standard.
However, there are some plating specifications in the JEDEC component standards.

Dear Technos,

For applications other than ENIG, like, for instance, gold plated Cu pins, is there any standard (ASTM?) specifying the thickness of the Ni barrier that would prevent Cu diffusion towards the surface?

Thank you,
