Cette troisième édition annule et remplace la seconde édition parue en 1999 et constitue une révision technique. Les principales modifications apportées à l'édition précédente sont les suivantes: - amendements résultant de modifications des normes de performance OMI relatives aux instruments de mesure de la vitesse et de la distance pour navires (Lochs) définis en 2000 dans la résolution MSC.96(72). Ces amendements réduisent à 2 m la profondeur minimale de l'eau sous la quille de l'équipement par rapport au fond afin d'assurer le bon fonctionnement des instruments de mesure de la vitesse et de la distance pour navires (Lochs), réduisent la précision requise des écrans analogiques et ajoutent une exigence relative à une interface série.

Overview

EN 61023:2007 (adoption of IEC 61023:2007) defines the performance requirements, test methods and required test results for marine Speed and Distance Measuring Equipment (SDME). It implements the SDME provisions of SOLAS Chapter V (Regulation 19) and is based on IMO Resolution MSC.96(72). The standard is associated with IEC 60945 and was adopted by CENELEC/CLC to harmonize European and international requirements for shipborne speed and distance sensors and displays.

Key topics and technical requirements

• Scope: Minimum performance requirements for devices that indicate forward speed and distance through the water or over the ground (SDME).
• Performance vs. environment: Devices measuring through-water speed must meet performance in water depth > 3 m under the keel; ground‑based (GNSS/ground-referenced) SDME are required to operate correctly with water depth ≥ 2 m.
• Accuracy & presentation: Defines accuracy requirements for speed and distance indications and methods of presenting speed (analogue/digital). The 2007 edition reduced the accuracy required of analogue displays.
• Testing methods: Specifies test arrangements, test procedures and required test results for speed indication, distance run, roll and pitch effects, and environmental influences.
• Interfaces: Adds a requirement for a serial interface (digital output) to support integration with other bridge systems and external displays.
• Construction & installation: Requirements for mounting, system configuration, optional facilities, and how SDME combinations (sensor + remote display) are tested as an integrated system.
• Standards linkage: Cross-references and alignment with IMO MSC.96(72) clauses; normative dependence on IEC 60945 for general maritime equipment testing methods.

Applications and who uses it

• Shipbuilders and system integrators use EN 61023:2007 to select and install compliant SDME for newbuilds and retrofits to meet SOLAS requirements.
• Equipment manufacturers design and test SDME (through‑water log sensors, ground‑referenced modules, displays, digital outputs) against the standard’s test methods and performance criteria.
• Flag administrations, surveyors and classification societies refer to the standard during statutory inspection and certification of navigation equipment.
• Test laboratories and QA teams apply the specified methods of testing and required test results for type approval and production verification.
• Bridge operators and marine electronics installers rely on the standard to ensure accurate speed/distance data for navigation, collision avoidance and track control systems (e.g., radar plotting aids).

Related standards

• IEC 61023 (IEC version) / EN 61023:2007
• IEC 60945 (general requirements and test methods for maritime equipment)
• IEC 61162-1 (digital interfaces - NMEA/serial talker/listener)
• IMO Resolution MSC.96(72) and SOLAS Chapter V (Regulation 19)

EN 61023:2007 is essential reading for maritime stakeholders implementing or certifying SDME to ensure compliant, interoperable and reliable speed and distance measurements on board ships.

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 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 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 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 agreements 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 use 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 promote 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 indicated 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 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) and
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.
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 61023 has been prepared by IEC technical committee 80: Maritime
navigation and radiocommunication equipment and systems.
This third edition cancels and replaces the second edition published in 1999. It constitutes a
technical revision.
The main technical changes with regard to the previous edition are listed below:
− amendments resulting from changes to the IMO performance standards for SDME
agreed in resolution MSC.96(72) in 2000. The amendments reduce the minimum depth
of water under the keel for correct operation of the SDME to 2 m for a ground based
equipment, reduce the accuracy required of analogue displays and add a requirement
for a serial interface.

distance measuring equipment (SDME) required by Regulation 19 of Chapter V of the
International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, and which
is associated with IEC 60945.
This standard is based upon the requirements of IMO Resolution MSC.96(72). The clause
numbering of that resolution is indicated in parentheses in Clause 4 and all subclauses whose
meaning is identical to that in the resolution are printed in italics.
In the tests of Clause 5, the corresponding requirement of Clause 4 is indicated in
parentheses. The cross-references between the IMO performance standards in Resolution
MSC.96(72) and the tests of this standard are summarized in Annex A.
