15、 (c) BSI -363168991:CEI 1 7 INTERNATIONAL ELECTROTECHNICAL COMMISSION ELECTRICAL INSTALLATIONS OF SHIPS AND MOBILE AND FIXED OFFSHORE UNITS Part 1: Procedures for calculating short-circuit currents in three-phase a.c. FOREWORD 1)The IEC (International Electrotechnical Commission) is a worldwide orga
16、nization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the 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 activit
17、ies, the IEC publishes International Standards. Their preparation is entrusted to technical committees; 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
18、participate in this preparation. The IEC collaborates closely with the International Organization 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
19、possible, an international consensus of opinion on the relevant subjects since each technical committee 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 re
20、ports or guides and they are accepted by the National Committees in that sense. 4)In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergenc
21、e between the IEC Standard and the corresponding national or regional standard shall be clearly 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)Att
22、ention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. This part of International Standard IEC 61363 has been prepared by IEC technical commi
23、ttee 18: Electrical installations of ships and of mobile and fixed offshore units. This standard cancels and replaces IEC 60363, published in 1972. The text of this standard is based on the following documents: FDISReport on voting 18/831/FDIS18/837/RVD Full information on the voting for the approva
24、l of this standard can be found in the report on voting indicated in the above table.
