CEE 7 standards
The International Commission on the Rules for the Approval of Electrical Equipment (IECEE) was a standards body which published Specification for plugs and socket-outlets for domestic and similar purposes as CEE Publication 7, known simply as CEE 7. It was originally published in 1951, the 2nd edition was published in May 1963 and was last updated by Modification 4 in March 1983. CEE 7 consists of general specifications, plus a number of standard sheets for specific connectors.
A number of standards based on two round pins with centers spaced at 19 mm are in use in continental Europe and elsewhere, most of which are listed in IEC/TR 60083 “Plugs and socket-outlets for domestic and similar general use standardized in member countries of IEC”. There is no European Union regulation of domestic mains plugs and sockets, and the Low Voltage Directive specifically excludes domestic plugs and sockets. EU countries each have their own regulations and national standards; for example, some require child-resistant shutters, while others do not. CE marking is neither applicable nor permitted on plugs and sockets.
