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.

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.

4 Performance requirements
4.1 Radar indication
The radar equipment shall provide an indication, in relation to own ship, of the position of
other surface craft/obstructions, buoys, shorelines and navigational marks, in a manner which
will assist in navigation and in avoiding collision.
4.2 Safety of options
The equipment, including facilities that are provided in addition to those required herein, shall
not degrade the radar performance as specified in 4.1. The manufacturer shall provide
information for all options available.
4.3 Technical information
Adequate information shall be provided and shall include a manual to enable the equipment to
be properly installed, set up, routinely maintained and operated. The manufacturer shall
declare that the manual contains adequate information to meet this requirement.
4.4 Quality assurance
The manufacturer shall have a quality control system in place for production, final-product
inspection and testing that is audited by a competent authority to ensure continuous
compliance with the certified product. Alternatively, the manufacturer may use final product
verification procedures where a competent authority verifies compliance with the equipment
certification before the product is installed.
4.5 Radio-frequency spectrum requirements
The operational radio-frequency of the equipment shall be within the appropriate bands
allocated for radionavigation defined in the ITU Radio Regulations at all times. (see also
Annex D).
4.6 Range
With the radar antenna mounted at a height of 7,5 m above sea level, the operational
requirement under normal propagation conditions is that the equipment shall, in the absence
of clutter, paint the radar target echoes as detailed in 4.6.1 and 4.6.2 for at least 8 out of 10
radar scans.

4.6.1 Coastlines
• At 9 nautical miles class A (5 nautical miles class B and C) when the ground rises to 60 m.
• At 5 nautical miles class A (3 nautical miles class B and C) when the ground rises to 6 m.
4.6.2 Surface objects
• At 5 nautical miles class A (3 nautical miles classes B and C) a radar reflector, having an
effective echoing area of 400 m , mounted at a height of 7,5 m.
• At 2 nautical miles class A (1 nautical mile classes B and C) a radar reflector, having an
effective echoing area of 10 m , mounted at a height of 3,5 m.
• At 1 nautical mile class A (classes B and C not applicable) a radar reflector, having an
effective echoing area of 5 m , mounted at a height of 3,5 m.
NOTE The 7,5 m and the 3,5 m height referred to in 4.6 are test criteria only and not an installation requirement.
This can be achieved using triangular corner reflectors of 201 mm, 225 mm and 570 mm for the “a” dimension,
2 2 2
calculated for X-band are equivalent to echoing areas of 5 m , 10 m and 400 m respectively.
4.6.3 Minimum range
A 10 m test target, set at a height 3,5 m shall be clearly displayed from a minimum horizontal
range of 50 m for class A, (60 m for class B) and (75 m for class C) from the antenna position.
Without changing the setting of controls other than the range selector, the test target shall
remain visible from the minimum horizontal range, up to a range of 1 nautical mile.
NOTE The minimum range is the shortest distance at which a stationary target echo ahead is still presented
separately from the point representing the antenna position.
4.7 Display
4.7.1 Display size
The equipment shall provide, without external magnification, a display with a minimum
effective diameter within the bearing scale of not less than 150 mm class A (85 mm class B)
(75 mm class C).
Other technologies that achieve the same functional requirements are permitted.
4.7.2 Standard ranges
The equipment shall provide the following set of range scales of display; 0,75, 1,5, 3, 6 and
12 nautical miles. Intermediate range scales are not permitted for class A but may be
provided for class B and class C.
An additional range of 0,25 nautical miles for class B and C shall be provided.
