23、 MEASURING METHODS - Part 23-3: Test 23c: Shielding effectiveness of connectors and accessories FOREWORD The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of th

24、e IEC is to promote international co-operation 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 committees; any IEC National Com

25、mittee 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 for Standardization (SO) i

26、n accordance with conditions determined by agreement between the two organizations. 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 committee has representation from

27、 all interested National Committees. The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. In order to promote int

28、ernational 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 indicated

29、 in the latter. 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. Attention is drawn to the possibility that some of the elements of this International Standard may be the subjec

30、t of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 6051 2-23-3 has been prepared by subcommittee 488: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equi

31、pment. The text of this standard is based on the following documents: Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that the contents of this publication will remain unchanged until 2004. At this date, the publication will be reconfirmed; withdrawn; amended. replaced by a revised edition, or
