1) The International Electrotechnical Commission (IEC ) is an international scope by all national Electrotechnical Commission (IEC NC) consisting of standardization organizations. Its purpose is to promote international cooperation on all questions concerning standardization in the electrical and electronic fields. For this reason, IEC carry out related activities, And publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specification (PAS), Guide (hereinafter collectively referred to as the IEC publication). These standards entrusted to technical committees. Any IEC National Committee interested in the subject dealt with may participate Plus development work. IEC linked with international, governmental and non-governmental organizations may also participate in the development of standards. IEC and the National Inter Organization for Standardization (ISO ) in close cooperation on the basis of the agreement between the two organizations. 2) IEC technical aspects of formal decisions or agreements, the technical committee of the National Commission on all their interest to participate in the formulation of. Therefore, these decisions or agreements are expressed as related issues consensus in the international arena. 3) IEC standard manner recommended for international use and are accepted by the National Committees in that sense. In order to ensure that the IEC When the accuracy of the technical content of the publication was made all reasonable efforts to IEC standards are used and their ultimate use any Family misunderstanding is not responsible.
4) In order to promote international unification, National Committees to ensure maximum use of international standards in their national or regional standards quasi. IEC standards corresponding to any difference between the national or regional standard must make clear that in the latter. 5) IEC provides no marking to indicate its approval procedures, but does not mean any equipment declared to comply with certain criteria to take responsibility. 6) All users should ensure that they have the latest version of this section. 7) IEC or its managers, employees, agents or support staff (including members of the Independent Expert and Technical Commission) and IEC National Committees We will not deal with the use of any personal injury or rely on this publication or other IEC IEC publication caused property damage or other Direct or indirect loss of any property, or from outside of this publication costs (including legal fees) and expenses responsibility. 8) It should be noted in this section are listed reference standard (normative references). For proper use of this section is concerned, the use of a reference standard Quasi (Normative references) is indispensable.
Content 9) should be noted that certain provisions of this International Standard may involve patent rights, IEC will not be liable to confirm the patent. This part of International Standard IEC 60335 developed by IEC technical committee 61 "Household and similar electrical appliances." This section is based on the 5th edition (2002) and its Addendum 1 to develop, based on the following documents. FDIS Report on voting
