24、ON EQUIPMENT - Part 2: Sectional specification for signal transformers on the basis of the capability approval procedure FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National C

25、ommittees). The object of the IEC is to promote international cooperation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical commi

26、ttees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization

27、 for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters, express as nearly as possible an international consensus of opinion on the relevant subjects since each technical com

28、mittee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to p

29、romote international unification. IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

30、 indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard m

31、ay be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 1248-2 has been prepared by IEC technical committee 51: Magnetic components and ferrite materials. This standard is intended for use in the IEC Quality Asse

32、ssment System for Electronic Components (IECQ). 1 51/399/FDIS I 51/428/RVD I Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.
