IEC Preface
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of national electrotechnical committees (IEC National Committees). The mission of IEC is to promote international cooperation on various standardization issues in the field of electrotechnical engineering. To this end, in addition to organizing other activities, it also publishes various international standards. The IEC international standards are entrusted to technical committees for formulation. Any IEC National Committee interested in the issue under discussion can participate in this formulation work. International organizations, governmental organizations and non-governmental organizations that have established relations with IEC can also participate in this formulation work. 1IEC cooperates closely with the International Organization for Standardization (ISO) under the conditions stipulated in the agreement it has reached with it. 2) Formal resolutions or agreements of IFC on technical issues are formulated by technical committees represented by national committees that are particularly interested in the issue, and express the international consensus on the issue as accurately as possible. 3) These resolutions or agreements are published in the form of standards, technical reports or guidelines, and are recommended for international use and accepted by national committees in this sense.
4) In order to promote international uniformity, IEC National Committees undertake to adopt EC International Standards as faithfully as possible in their national or regional standards. Any inconsistencies between IEC standards and corresponding national or regional standards should be clearly pointed out in the national or regional standards as far as possible.
5) IEC provides recognized non-marking procedures, but is not responsible for the verification of equipment that is not in compliance with its standards. International Standard IEC884-2-5 was prepared by SC23H: Plugs, Sockets and Switches, Technical Committee SC23: Electrical Accessories, IEC TC23. This publication is based on the following documents:
