Dürrer,
The table in the Wikipedia article
https://en.wikipedia.org/wiki/Galvanic_corrosion#Anodic_index
has more entries, is more descriptive, and doesn't totally agree with
Table 7-1 on page 156 of Gershon J. Wheeler's book, The Design of
Electronic Equipment: A Manual for Production and
?
Kind regards,

Betreff: [PSES] Friday Question - table of electrochemical potentials
For years, I've used the same or similar table for dissimilar metals and the
possibility of corrosio
For years, I've used the same or similar table for dissimilar metals and
the possibility of corrosion for "pairs of common metals in use". This
table shows up in many IEC based standards and no one I know questions the
validity. I got curious as to the source and why this particular list of
"common

all sorts of other stuff present.

All,
Is anyone aware of some resource which expands on the electrochemical
potentials table found in IEC 60950 Annex J?
I am attempting to correlate this table to other resources and include
metals which are not found on the IEC version. It is obvious this table

Group,
Has anyone ever used a combination of metals not listed in annex J of
EN60950 for a protective earthing connection? If so can anyone suggest a decent
source of information on electrochemical potentials for various materials.
