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 62252 has been prepared by IEC technical committee 80: Maritime
navigation and radiocommunication equipment and systems.
This standard is based on the standards for radar and radar plotting used on SOLAS vessels,
IEC 60872 series, IEC 60936 series and IEC 60945.
The text of this standard is based on the following documents:
FDIS Report on voting
80/393/FDIS 80/397/RVD

voting indicated in the above table.

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

INTRODUCTION
This IEC radar standard is produced specifically for radar not fully compliant with the IMO
Performance Standard for radar/radar plotting and applies to the following:
• radar (class A) intended for commercial craft under 150 gross tonnage, where no SOLAS
radar carriage requirement currently exists, where the antenna beamwidth is not more
than 4,0° and the display minimum effective diameter is limited to not less than 150 mm.
• radar (class B) intended for recreational craft or other maritime use and where the
antenna beamwidth is not more than 5,5° and the display minimum effective diameter is
limited to not less than 85 mm.
• radar (class C) intended for small recreational craft where the antenna beamwidth is not
more than 7,5° and the display minimum effective diameter is limited to not less than
75 mm.
The requirements for commercial craft radar are covered in the main body of this
specification. The requirements, where different, for radar (class B and C) are shown in
parenthesis where applicable.
NOTE 1 The IMO performance standard for radar/radar plotting is in Resolution MSC.64(67) which is
implemented in the IEC 60872 series and the IEC 60936 series of standards.
NOTE 2 For the purposes of this IEC standard, the words 'craft’ and ‘ship’ are interchangeable and have the
same meaning.
