GB 4706. 56-2002/1EC 60335-2-13:19931) IEC (International Electrotechnical Commission) is an international standardization organization composed of all national electrotechnical committees (IEC National Committees). Its purpose is to promote international cooperation on standardization issues in the electrical and electronic fields. To this end, IEC carries out international standardization activities and publishes international standards. The formulation of these standards is entrusted to technical committees. Any IEC National Committee interested in the technical issue can participate in the formulation work. International, governmental and non-governmental organizations associated with IEC can also participate in this work. IEC and the International Organization for Standardization (ISO) work closely on the basis of an agreement between the two organizations. 2) Formal resolutions or agreements of IEC on technical issues formulated by technical committees in which all national committees with special interest in the issue participate, represent as far as possible the international consensus on the issues involved. 3) These formal resolutions or agreements are published in the form of standards, technical reports or guidelines, and are accepted by the National Committees in this sense.
4) In order to achieve international consensus, IEC National Committees agree to use IEC in their national and regional standards to the greatest extent possible. International Standard.
