The CE marking is a European proof of conformity and is also known as "Trade Passport to Europe" that allows manufacturers and exporters to circulate products freely within the 15 European Union (EU) members. The letters, "CE" -- French for "Conformité Européne," indicate that the manufacturer has satisfied all assessment procedures specified by law for its product to be sold on the European market.
Although consumers may perceive the CE marking as a quality mark, it is not. The CE mark stands for the minimum safety requirements. The CE marking addresses itself primarily to the national surveillance authorities of the member states, and its use simplifies their task. Just looking at the CE marking will not tell surveillance authorities to which directive a given product complies. Rather, it is the declaration of conformity that contains the details of the directive(s) to which the product complies and the standards that were relied upon in assuring compliance.
The CE marking must be affixed to the product, to its data plate or, where this is not possible or not warranted on the account of the nature of the product, to its packaging, if any, and to the accompanying documents by the manufacturer, the authorized representative in the community or, in exceptional cases, by those responsible for placing the product on the market. The CE marking must be affixed visibly, legibly and indelibly. Where special provisions do not impose specific dimensions, the CE Marking must have a height of at least 5 millimetres.
