25、ncy position indicating radio beacon operating on 406 MHz Operational and performance requirements, methods of testing and required test results FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical co
26、mmittees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications, Techni
27、cal Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, government
28、al and non- governmental organizations liaising with the IEC also participate in this preparation. 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 ag
29、reements of 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 IEC National Committees. 3) IEC Publications have the form of recommendations for international us
30、e and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to prom
31、ote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indic
32、ated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach
33、to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) a
34、nd expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication.
35、9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. 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 committee 80: Maritim
36、e navigation and radiocommunication equipment and systems. This third edition cancels and replaces the second edition, published in 2002, of which it constitutes a technical revision. The significant changes in this edition include revised characteristics for the low duty cycle light in 3.3.3 c), to
37、gether with a revised test in 5.3.3.3, to allow the use of white LEDs. Requirements for retro-reflecting material and the lanyard have been clarified in 3.3 noting the ever decreasing size of EPIRBs, and requirements for equipment manuals and labelling clarified in 3.11 and 3.12. Battery life requir
38、ements have been clarified in 4.6.2. The test methods have been generally revised to align with the latest editions of COSPAS- SARSAT T.001 and T.007 and IEC 60945. An extra test requirement for a drop onto a hard 6 61097-2 IEC:2008(E) surface has been added, together with further frequency bands fo
39、r the measurement of spurious emissions to protect aeronautical communications. Annex B, which reproduced some COSPAS-SARSAT material has been deleted and replaced with a new annex giving requirements for EPIRBs associated with navigation devices. Annex C, concerning EPIRBs without a float free mech
40、anism, has been expanded and Annex D, concerning the homing device, includes a new radiated power test “off ground plane” and clarification to the measurement of spurious emissions. The text of this standard is based on the following documents: CDV Report on voting 80/480/CDV 80/514/RVC Full informa
41、tion 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. A list of all parts of the IEC 61097 series, under the general title Global maritime distress a
42、nd safety system (GMDSS), can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date
43、, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 61097-2 IEC:2008(E) 7 GLOBAL MARITIME DISTRESS AND SAFETY SYSTEM (GMDSS) Part 2: COSPAS-SARSAT EPIRB Satellite emergency position indica
44、ting 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 minimum performance requirements, technical charac- teristics and type-testing requirements of the satellite emergency position-i
45、ndicating 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 Convention for Safety of Life at Sea (SOLAS), and which is associated with IEC 60945. When a requirement in this standard is differ
46、ent from IEC 60945, the requirement in this standard takes precedence. This standard incorporates the performance standards of IMO Resolution A.810(19), the International Telecommunication Union (ITU) Radio Regulations as well as the technical characteristics for such transmitters contained in Recom
47、mendation ITU-R M.633, and takes account of the general requirements contained in IMO Resolution A.694(17). This standard further takes account of IMO Resolution A.696(17) concerning the type approval of satellite EPIRBs. This standard also includes minimum performance standards for a non-float-free
48、 satellite EPIRB without float-free release mechanism (see Annex C). NOTE 1 Although a number of the requirements and tests may be similar this standard is not intended to be used with 406 MHz Ship Security Alert System (SSAS) Beacons. All texts of this standard, whose wording is identical to that i
49、n the IMO SOLAS Convention 1974 as amended and Resolutions A.662(16), A.694(17), A.702(17) and A.810(19) and Recommendation ITU-R M.633 will be printed in italics and the Resolution/Recommendation and paragraph number indicated between brackets. NOTE 2 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 throughout the temperature range of 30 C to +65 C. T
