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 60872-3 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
80/251/FDIS 80/274/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, C and D form an integral part of this standard.

The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be

 reconfirmed;
 withdrawn;
 replaced by a revised edition, or

 amended.
A bilingual version of this standard may be issued at a later date.

MARITIME NAVIGATION AND RADIOCOMMUNICATION

EQUIPMENT AND SYSTEMS – RADAR PLOTTING AIDS –

Part 3: Electronic plotting aid (EPA) -–

Performance requirements –
Methods of testing and required test results

1 Scope
This part of IEC 60872 specifies the minimum operational and performance requirements,
methods of testing and test results for equipment that complies with performance standards not
inferior to those adopted by the International Maritime Organization (IMO) in resolution MSC.64
(67) Annex 4 – Appendix 2. In addition, this standard takes account of IMO Resolution A.694
and is associated with IEC 60945.
When a requirement in this standard is different from IEC 60945, the requirement in this
standard takes precedence.
The electronic plotting aid for manual direct plotting is intended for small ships fitted with either
a gyrocompass or a transmitting marine electromagnetic compass conforming to ISO 11606 or
a transmitting magnetic heading device conforming to IMO MSC.86(70) – annex 2, and a speed
and distance measuring equipment (SDME) conforming to IMO Resolution A.824 and
IEC 61023. This plotting aid is not suitable for ships classed as high-speed craft.
All texts in this standard, the wording of which is identical to that in IMO resolution MSC.64 (67)
Annex 4 – Appendix 2, are printed in italics and the resolution and paragraph numbers are
indicated in brackets.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60872. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
based on this part of IEC 60872 are encouraged to investigate the possibility of applying the
most recent editions of the normative documents indicated below. For undated references, the
latest edition of the normative document referred to applies. Members of IEC and ISO maintain
registers of currently valid International Standards.

3 Performance requirements
3.1 Introduction
3.1.1 The electronic plotting aid (EPA) shall, in order to improve the standard of collision
avoidance at sea:
.1 reduce the workload of observers by enabling them to obtain information about plotted
targets so that they can perform as well with several separate targets as they can by
manually plotting a single target;
.2 provide continuous, accurate and rapid situation evaluation.
3.1.2 The radar facilities provided by an EPA display shall comply with those clauses of
IEC 60936-1 appropriate to its mode of use.
3.1.3 In addition to the general requirements contained in IEC 60945, the EPA shall comply
with the following minimum requirements.
3.1.4 Additional ARPA or ATA facilities, not mandated in this EPA standard, may be provided.
Such facilities shall comply with IEC 60872-1 and IEC 60872-2 as applicable.
