24、ods of testing and required test results FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on al
25、l 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 Committee interested in the subject dealt with may part
26、icipate 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 (ISO) in accordance with conditions determined by agreemen
27、t 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 committee has representation from all interested National Committees. 3) The docu
28、ments 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 promote international unification, IEC National Committees undertake to apply I
29、EC 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 in the latter. 5) The IEC provides no marking procedure to indicate
30、 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 may be the subject of patent rights. The IEC shall not be held responsible for
31、identifying any or all such patent rights. International Standard IEC 1097-12 has been prepared by IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems. The text of this standard is based on the following documents: FDIS Report on voting 80/126/FDIS 80/136/RVD
32、 Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. Annexes A and B form an integral part of this standard. Annex C is for information only. The French version of this standard will be issued separately. 4 109712 IEC:19

34、equirements, technical charac- teristics and methods of testing with required test results of survival craft portable two-way radiotelephone apparatus as required by chapter III of the 1988 amendments to the 1974 International Convention for the Safety of Life at Sea (SOLAS), and which is associated
35、 with IEC 945. When a requirement in this standard is different from IEC 945, the requirement in this standard shall take precedence. This standard incorporates the applicable parts of the performance requirements included in IMO Resolution A.809(19) annex 1 and the technical characteristics include
36、d in ITU M.489-2 and ITU-R M.542-1, and takes account of the general requirements contained in IMO Resolution A.694(17), and conforms with the ITU Radio Regulations where applicable. NOTE All text of this standard, whose wording is identical to that in IMO Resolutions A.809(19) and A.694(17) and ITU
37、R M.4892 is printed in italics and the Resolution/Recommendation and paragraph numbers are indicated in brackets. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 1097. At the time of publicat
38、ion, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 1097 are encouraged to investigate the possibility of applying the most recent edition of the normative documents indicated below.
