I think you are confusing data and standards. Electrochemical potential is data
that goes back over three centuries when Voltaire and others started measuring
it. The first place I ever saw it published was in my father's copy of the
Handbook of Chemistry and Physics, 19th edition. by the

Thank you for your response, David. I am entirely uncertain
that the hydrogen reference electrode was

I have plans to try additional reference texts on a visit to
the local university library, hopefully later this week.
I started out searching for a good lookup table. Then in

I understand that the origins were a US MIL spec. Although I have not
checked, I seem to recall that pretty much the same information was also
contained in IEC 380. We are therefore going way, way, back in the annals of
time.

Tin plating has an anodic index of 0.6V
Copper itself has an anodic index of 0.35V
For tin plated copper; I would use 0.6V.
