I stumbled over following quote while searching for japanese color coding:
>Russia
>The Soviet Republics use a standard plug and >socket defined in Russian Standard Gost 7396, >which is similar to the CEE 7/7 ("Schuko") standard. Contacts are also on 19mm centers, but the
diameter of this contact is 4.0mm compared to 4.8mm which is standard in Continental Europe. Reliable information on Eastern European standards is still difficult to access. The standard used in
the former Yugoslavia is virtually identical to the Schuko standard. Furthermore, one of the protocols governing the reunification of Germany provided that the DIN and VDE standards would
prevail without exception. The former East Germany was required to conform to the Schuko standard.
