IEC Preface
1) IEC (International Electrotechnical Commission) is an international standardization organization composed of all national product associations (IEC four major organizations). IEC's purpose is to promote international cooperation on all problems related to standardization of electrical and electronic fields. For this purpose and the main activities of the IEC, IEC publishes international standards. Standards are formulated by technical committees. Any national committee interested in the subject may participate in its formulation. International organizations, governmental and non-governmental organizations related to IEC may also participate in the formulation of standards. IEC and the International Organization for Standardization maintain close cooperation in accordance with the existing trade relations between the two organizations. 2) Each technical committee has representatives of all national committees concerned with these issues, and formal decisions and agreements on the standards are also made. 3) IEC documents are published in the form of recommendations for international use in the form of standards, technical notices or guidelines. In this sense, 1. For the acceptance of the National Committee of the IEC, the national members of the IEC will apply IEC international standards to their national and regional standards to the greatest extent possible. 4) In order to promote international uniformity, any differences between IEC standards and corresponding national or regional standards should be clearly indicated in the implementation. S) IEC has not proposed a procedure for marking equipment conformity. Therefore, when a certain equipment conforms to an IEC standard, IEC does not accept this. 5) Please note that some of the contents of this International Standard may be related to patent rights. IEC will not be responsible for confirming these patent rights. A International Standard prepared by TEC/TCI Working Group 10 on Electrotechnical Terminology. This second edition of this International Standard replaces the first edition prepared in 1970. The rates of this standard are based on the following documents: Draft Standard
