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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.

MARITIME NAVIGATION AND RADIOCOMMUNICATION
EQUIPMENT AND SYSTEMS –
Electronic chart system (ECS) –
Operational and performance requirements,
methods of testing and required test results
1 Scope
This International Standard specifies the minimum operational and performance requirements
and methods of testing for ECS. ECSs are designed or adapted for use as navigation
information systems on vessels not required to comply with Chapter V of the International
Convention for the Safety of Life at Sea (SOLAS).
Different types of vessels, for example, a non-SOLAS passenger vessel, a small fishing
vessel or a recreational vessel, which operate in different environments, need to be equipped
with navigational systems providing functionality to meet their needs. If the full functionality of
ECDIS according to IEC 61174 is considered to be unnecessary, ECS may be suitable for a
navigation information system for these vessels. Governments may consider requiring the
carriage of ECS for these vessels under local arrangements.
In order to provide a standard that can be used to apply different levels of navigational
functionality, three classes of ECS are defined.
• Class “A” ECS are designed or adapted for use as a primary navigation information
system.
• Class “B” ECS are designed or adapted for use as a navigation information system where
less navigational functionality is required than Class “A”.
• Class “C” ECS are designed or adapted for use as a navigation information system with
minimal functionality intended to plot and monitor a vessel’s position.
Within this International Standard, the beginning of each paragraph indicates the applicability
to ECS Class(es). Paragraphs marked “(A B C)” apply to all Classes; paragraphs marked “(A
B)” or “(B C)” apply only to those specific combinations of Classes; and paragraphs marked
“(A)”, “(B)” or “(C)” apply only to those individual Classes.
For a Class “A” and Class “B” ECS, adequate back-up arrangements may be required to
ensure safe navigation in the event of an ECS failure. For a Class “A” ECS, an additional
Class “A” ECS may be used as the back-up. Alternatively, Class “B” ECS are intended to
meet the minimum requirements for adequate back-up arrangements for Class “A” ECS. For a
Class “B” ECS, an additional Class “B” ECS may be used as the back-up. Class “C” ECS are
not intended to meet the minimum requirements for adequate back-up arrangements for Class
“A” or Class “B” ECS.
Guidance for testing ECS is given in Annex A.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.

MARITIME NAVIGATION AND RADIOCOMMUNICATION
EQUIPMENT AND SYSTEMS –
Electronic chart system (ECS) –
Operational and performance requirements,
methods of testing and required test results
1 Scope
This International Standard specifies the minimum operational and performance requirements
and methods of testing for ECS. ECSs are designed or adapted for use as navigation
information systems on vessels not required to comply with Chapter V of the International
Convention for the Safety of Life at Sea (SOLAS).
Different types of vessels, for example, a non-SOLAS passenger vessel, a small fishing
vessel or a recreational vessel, which operate in different environments, need to be equipped
with navigational systems providing functionality to meet their needs. If the full functionality of
ECDIS according to IEC 61174 is considered to be unnecessary, ECS may be suitable for a
navigation information system for these vessels. Governments may consider requiring the
carriage of ECS for these vessels under local arrangements.
In order to provide a standard that can be used to apply different levels of navigational
functionality, three classes of ECS are defined.
• Class “A” ECS are designed or adapted for use as a primary navigation information
system.
• Class “B” ECS are designed or adapted for use as a navigation information system where
less navigational functionality is required than Class “A”.
• Class “C” ECS are designed or adapted for use as a navigation information system with
minimal functionality intended to plot and monitor a vessel’s position.
Within this International Standard, the beginning of each paragraph indicates the applicability
to ECS Class(es). Paragraphs marked “(A B C)” apply to all Classes; paragraphs marked “(A
B)” or “(B C)” apply only to those specific combinations of Classes; and paragraphs marked
“(A)”, “(B)” or “(C)” apply only to those individual Classes.
For a Class “A” and Class “B” ECS, adequate back-up arrangements may be required to
ensure safe navigation in the event of an ECS failure. For a Class “A” ECS, an additional
Class “A” ECS may be used as the back-up. Alternatively, Class “B” ECS are intended to
meet the minimum requirements for adequate back-up arrangements for Class “A” ECS. For a
Class “B” ECS, an additional Class “B” ECS may be used as the back-up. Class “C” ECS are
not intended to meet the minimum requirements for adequate back-up arrangements for Class
“A” or Class “B” ECS.
Guidance for testing ECS is given in Annex A.
