Source-derived summary

CEE 7 is a standard for alternating-current (AC) plugs and sockets for household and similar purposes. First published in 1951 by the former International Commission on the Rules for the Approval of Electrical Equipment (IECEE), it unified standards produced by several continental European countries. The project resulted in a list and numbered group of power connecter systems.

In Europe, CEE 7 connectors are the sole standardised system in use (and therefore often referred to as "European plugs/sockets") with the exceptions of Italy (with San Marino), Denmark (including the Faroe Islands), Great Britain (including Gibraltar) with Ireland, Malta and Cyprus, and Switzerland (including Liechtenstein), each of which use their own systems. CEE 7 is also the sole system in many other countries outside the region such as Indonesia, Iran, Egypt, DR Congo, Morocco, Madagascar and South Korea.

Background

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. It remains available from the IEC, which states that "this standard shall not be used alone, it is to be used in addition to IEC 60884-1". 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 centres 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".

Editorial summary

“CEE 7” enters the record as system of standards for electrical equipment in the European Economic Community. Crown Archives preserves that source wording while asking what system, standards and electrical can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1951, 1963, 1983—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around system, standards and electrical.
Editorial analysis

Why this record matters

“CEE 7” is worth following because a concise public description often conceals a longer documentary argument. Here, system, standards and electrical provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q1023315. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1951, 1963 and 1983.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
