DIN60320 ist wohl eher was für Gerätesteckverbindungen.
Die "Schuko" ist irgendwo in älteren DINs zu finden:
- "The CEE 7/3 socket and CEE 7/4 plug are commonly called Schuko. The socket (which is often, in error, also referred to as CEE 7/4) has a predominantly circular recess which is 17.5 mm (0.689 in) deep with two symmetrical round apertures and two earthing clips on the sides of the socket positioned to ensure that the earth is always engaged before live pin contact is made. The plug pins are 4.8 by 19 mm (0.189 by 0.748 in). The Schuko connection system is symmetrical and unpolarised in its design, allowing line and neutral to be reversed. The socket also accepts Europlugs and CEE 7/17 plugs. It is rated at 16 A. The current German standards are DIN 49441:1972-06 "Two-pole plugs with earthing-contact 10 A 250 V≅ and 10 A 250 V–, 16 A 250 V∼" (which also includes CEE 7/7 plug) and DIN 49440-1:2006-01 "Two-pole socket-outlets with earthing contact, 16 A 250 V a.c."
Sind allerdings nicht frei erhältlich, deshalb kann ich hier auch nicht garantieren, dass das die exakte Quelle ist. Kann sein, dass ich sie im Geschäft habe...
Normalerweise haben Stecker bzw Dosen irgendwo die Kennzeichnung VDE und 16A. Darauf sollte man auch achten.
