17、GMDSS) Part 2: COSPAS-SARSAT EPIRB Satellite emergency position indicating radio beacon operating on 406 MHz Operational and performance requirements, methods of testing and required test results FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standard
18、ization 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 activities, the IEC publishe
19、s 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 participate in this p
20、reparation. 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 possible, an interna
21、tional 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 specifications, techn
22、ical 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 IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any d
23、ivergence 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 standar
24、ds. 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 identifying any or all such patent rights. International Standard IEC 61097-2 has been prepared by IEC technical commit
25、tee 80: Maritime navigation and radiocommunication equipment and systems. This second edition cancels and replaces the first edition, published in 1994, of which it constitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting 80/348/FDIS 80/3
26、51/RVD 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 2. The committee has decided that the contents of this publication will remain
27、unchanged until 2007. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 4 BSIEC610972:2002160-792 EI:C002(2)E 5 INTRODUCTION This revision of IEC 61097-2 is due to changes to the Radio Regulations, COSPAS-SARSAT requirements and amendments to th
28、e IMO performance standards for 406 MHz Satellite emergency position indicating radio beacons (EPIRBs). The document has been renumbered and rearranged to comply in certain aspects with ISO/IEC Directives, and the requirements have been regrouped in a more logical order. 5 BSIEC610972:2002 6 610-792
29、 EI:C002(2)E GLOBAL MARITIME DISTRESS AND SAFETY SYSTEM (GMDSS) Part 2: COSPAS-SARSAT EPIRB Satellite emergency position indicating radio beacon operating on 406 MHz Operational and performance requirements, methods of testing and required test results 1 Scope This part of IEC 61097 specifies the mi
30、nimum performance requirements, technical charac- teristics and type-testing requirements of the satellite emergency position-indicating radio beacon used in the COSPAS-SARSAT satellite system (satellite EPIRB), as required by Regulation IV/7.1.6 of the 1988 amendments to the 1974 International Conv
31、ention for Safety of Life at Sea (SOLAS), and which is associated with IEC 60945 (General requirements). When a requirement in this standard is different from IEC 60945, the requirement in this standard shall take precedence. This standard also includes minimum performance standards for a manually a
32、ctivated satellite EPIRB without float-free release mechanism (see annex C). This standard incorporates the performance standards of IMO Resolutions A.810(19) Performance Standards for float-free satellite emergency position-indicating radio beacons (EPIRBs) operating on 406 MHz and A.662(16) Perfor
33、mance Standards for float-free release and activation arrangements for emergency radio equipment, the International Telecommunication Union (ITU) Radio Regulations as well as the technical characteristics for such transmitters contained in Recommendation ITU-R M.633 (as amended), and takes account o
34、f the general requirements contained in IMO Resolution A.694(17). All texts of this standard, whose wording is identical to that in the IMO SOLAS Convention 1974 as amended in 1988 and Resolutions A.658(16), A.662(16), A.689(17), A.694(17), A.696(17), A.702(17) and A.810(19)and Recommendation ITU-R
35、M.633 will be printed in italics and the Resolution/Recommendation and paragraph number indicated between brackets. NOTE 1 Classes of satellite EPIRBs considered in this document are: Class 1: Float-free (40 C to +55 C). The float-free release mechanism (A.662(16) should be capable of operating thro
36、ughout the temperature range of 40 C to +65 C.This class is not required by IMO Resolutions but may be applied at the discretion of each Administration. Class 2: Float-free (20 C to +55 C). The float-free release mechanism (A.662(16) should be capable of operating throughout the temperature range of
37、 30 C to +65 C. NOTE 2 Non-float-free, manually activated satellite EPIRBs in both classes are considered in annex C. NOTE 3 All classes shall include a 121,5 MHz homing device, described in annex D. User experience of COSPAS-SARSAT EPIRB operation leading to some clarification of IMO performance st
38、andards, and providing some useful information for satellite EPIRB users is included in annex E. 2 Normative references The following referenced documents are indispensable for the application of this document.
