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 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 60872-1 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems. The IEC 60872 series,
of which this is part 1, replaces IEC 60872 published in 1987 and amendment 1 (1991) and
reflects the new requirements of the International Maritime Organization (IMO).

The text of this standard is based on the following documents:
FDIS Report on voting
80/192/FDIS 80/207/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.
Annexes A, B, C, D and E form an integral part of this standard.
A bilingual version of this standard may be issued at a later date.

Methods of testing and required test results

1 Scope
This International Standard 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 A.823.
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 shall take precedence.
All texts of this standard, in which the wording is identical to that in IMO Resolution A.823, 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. At the time of publication, the editions indicated
were valid. All normative documents are subject to revision, and 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. Members of IEC and ISO maintain
registers of currently valid International Standards.

3 Performance requirements
3.1 (A.823/A.1) Introduction
(A.823/A.1.1) Automatic radar plotting aids (ARPA) shall, in order to improve the
3.1.1
standard of collision avoidance at sea:
.1 reduce the workload of observers by enabling them to obtain information about
automatically 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 (A.823/A.1.2) The radar facilities provided by an ARPA display shall comply with the
performance standards for radar equipment (Resolution A.477) appropriate to its mode of use.
3.1.3 (A.823/A.1.3) In addition to the general requirements contained in resolution A.694,
ARPA shall comply with the following minimum performance standards.

3.1.4 Where an ARPA display is intended for use as the master display of a complete radar
system, the system shall comply with IEC 60936-1. For high speed craft (HSC) ARPA, the
relevant clauses of IEC 60936-2 apply.
3.1.5 Where an ARPA display is intended for use as a slave display of a complete radar
system, it shall comply with the relevant clauses of IEC 60936-1, where applicable to such a
display. For high speed craft (HSC) ARPA, the relevant clauses of IEC 60936-2 apply.
3.1.6 Quality assurance
The ARPA shall be designed, produced and documented by companies complying with
ISO 9000, as applicable.
