EN is European Norm. According to the common obligations undertaken by the participating countries, the adoption of this EN standard will give legal status to the relevant national standards of a member state, or revoke the relevant standards of a certain country that is opposed to it. That is to say, the national standards of member states must be consistent with the EN standards. CENELEC and CEN and their joint body CEN/CENELEC are the leading standards-setting bodies in Europe. CENELEC was established in Brussels, Belgium in 1976, as a result of the merger of two earlier institutions. Its purpose is to harmonize the electrical standards promulgated by the relevant European countries' standards bodies and to eliminate technical barriers to trade.
