The CENELEC was formed in 1973 by two early European Commission Coordinating Committees (CENELCOM) and the European Electrotechnical Standards Coordinating Committee (CENEL), based in Brussels, with the aim of coordinating the Member States' electrical and electronic standards to eliminate technical barriers to trade. In the business scope, CENELEC is in charge of the standardization of electrical and electronic fields, while CEN manages other areas such as food, daily necessities, sporting goods and recreational facilities, health care, gas appliances, and mechanical engineering.

The general procedure for CENELEC to develop a uniform European standard is:

      (1) from the International Electrotechnical Commission (IEC), accounting for 80% of the total; second by the CENELEC technical unit project; The Committee on Electronic Technology; and the Electronic Technical Committee from Member States.

      (2) drafting: The drafting of the draft standard is mainly undertaken by the technical committee and the subcommittee.

      ③ comments: After the draft is completed, sent to the Member States for comments, this process takes 6 months. The drafting of the technical units to solicit the views of the full study, according to the rational elements of which to modify the final draft.
