26、required test results FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning
27、standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prep
28、aration 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 preparation. IEC collaborates closely
29、 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 IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant
30、subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the techn
31、ical 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum exte
32、nt possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for an
33、y 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 to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees
34、 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) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8
35、) 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. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rig
36、hts. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61996-2 has been prepared by IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems. This second edition cancels and replaces the first edition publi
37、shed in 2006, and constitutes a technical revision. A new requirement has been added to 4.3.6 for an interface to be used for downloading the stored data to an external computer. This is defined in Annex C which replaces the Annex C of the first edition which contained an IMO Circular which recommen
38、ded such an interface. An optional LAN interface for connection to radar has been added in 5.8. Some corrections to the text have also been made. 6 61996-2 IEC:2007(E) The text of this standard is based on the following documents: CDV Report on voting 80/471/CDV 80/500/RVC Full information on the vo
39、ting 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 61996 series, under the general title Maritime navigation and radiocommunicati
40、on equipment and systems Shipborne voyage data recorder (VDR), 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 t
41、he specific publication. At this date, 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. 61996-2 IEC:2007(E) 7 INTRODUCTION The S-VDR has been introduced by IMO for fitting to existing shi
42、ps as a simplified alternative to the voyage data recorder (VDR) which is required for all new ships. This part of IEC 61996 provides information on the testing requirements for S-VDR as defined in IMO performance standard MSC.163(78). The specification for S-VDR differs significantly from that for
43、VDR in two areas: a) the requirements for monitoring certain sensors are reduced when the data is not provided in IEC 61162 format, and b) the requirements for the protective S-VDR capsule are different from the VDR capsule, both for the fixed and float-free versions. Annex B provides a cross-refere
44、nce between this standard and IEC 61996-1 to aid test houses who may already have test results for VDRs which are being submitted as S-VDRs. Subsequent to publishing the performance standard for S-VDR, MSC.163(78), in 2004, the IMO sub-committee on Safety of Navigation (NAV) discussed the issue of d
45、ownload and playback of information. Recognising that after an accident there is a need for investigators to be able to download the stored data and playback the information from VDRs/S-VDRs without delay, the sub-committee agreed on recommended means for extracting stored data for investigation aut
46、horities. This was adopted by MSC.81 in 2005 as an amendment to resolution MSC.163(78) given in resolution MSC.214(81). This edition of the standard incorporates this amendment. 8 61996-2 IEC:2007(E) MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS SHIPBORNE VOYAGE DATA RECORDER (VDR
47、) Part 2: Simplified voyage data recorder (S-VDR) Performance requirements, methods of testing and required test results 1 Scope This part of IEC 61996 specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for simplified shipborn
48、e voyage data recorders (S-VDRs) as required by IMO MSC.163(78). It takes into account IMO resolution A.694(17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. NOTE All text of this standard, whose
49、wording is identical to that of IMO MSC.163(78) or A.861(20) is printed in italics, and the Resolution and associated performance standard paragraph numbers are indicated in brackets. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) ap
