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 all 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
participate 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 agreement 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 documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, 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 IEC 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 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 identifying any or all such patent rights.
International Standard IEC 60936-3 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
80/337/FDIS 80/342/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 3.
Annexes A, B and C form an integral part of this standard.
The committee has decided that the contents of this publication will remain unchanged until
2006. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

Part 3: Radar with chart facilities – Performance requirements –

Methods of testing and required test results

1 Scope
This part of IEC 60936 specifies the minimum operational and performance requirements,
methods of testing and required test results conforming to performance standards not inferior
to those adopted by the IMO in Resolution MSC.64(67) Annex 4 Radar clauses 3.3.9 and
3.3.10 for the optional requirements for superimposition of selected parts of SENC
information. In addition it takes account of IMO Resolution A.694 and is associated with
IEC 60945. When a requirement of this standard is different from IEC 60945, the requirement
in this standard shall take precedence.
A High Speed Craft (HSC) radar, as defined in IEC 60936-2, that uses ‘selected parts of the
SENC’ shall comply with the requirements of this standard.
This standard does not include the mandatory performance requirements for the shipborne
radar or HSC radar. These are specified in IEC 60936-1, Shipborne radar, and IEC 60936-2,
HSC radar respectively.
All text in this standard, whose wording is identical to that in IMO Resolution MSC.64(67)
Annex 4 is printed in italics and the Resolution (abbreviated to – A4) and paragraph numbers
are indicated in brackets, i.e. (A4/3.3).

3 Definitions and abbreviations
For the purposes of this part of IEC 60936 the following definitions and abbreviations apply.
3.1 Definitions
3.1.1
ECDIS
IEC 61174 ‘Electronic chart display and information system’ (ECDIS) means a navigation
information system which, with adequate backup arrangements, can be accepted as
complying with the up-to-date chart required by regulation V/20 of the 1974 SOLAS
Convention. It displays selected information from a system electronic navigational chart
(SENC) with positional information from navigational sensors to assist the mariner in route

planning and route monitoring, and by displaying additional navigation-related information.
The reference geodetic datum is WGS-84
3.1.2
SENC
System Electronic Navigational Chart (SENC) means a database resulting from the
transformation of the ENC for appropriate use, updates to the ENC by appropriate means, and
other data added by the mariner. It is this database that is actually accessed for the display
generation and other navigational functions, and which is the equivalent to an up-to-date
paper chart. The SENC may also contain information from other sources
