CE marking is a certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.
The mark consists of the CE logo and, if applicable, the four digit identification number of the Notified Body involved in the conformity assessment procedure.
"CE" originated in 1985 as an abbreviation of Conformité Européenne, meaning European Conformity, but is not defined as such in the relevant legislation. The CE marking is a symbol of free marketability in the European Economic Area (Internal Market).
