Overview

EN IEC 62923-2:2018 (published by CLC / CENELEC, identical to IEC 62923-2:2018) is part of the Bridge Alert Management series for maritime navigation and radiocommunication equipment and systems. This Part 2 defines harmonized, machine‑readable alert identifiers and reserved cluster identifiers to be used when implementing bridge alert management (BAM). The goal is to minimize differing identifiers for similar alerts, maintain machine‑readability, and support responsibility transfer between bridge systems and crew.

Key topics and requirements

• Standard alert identifiers: Annex A lists the official alert identifiers to be used for specific alerts. When an alert from Annex A is implemented, the exact identifier in Annex A must be used.
• Identifier range for custom alerts: Alerts not in Annex A must be assigned identifiers in the range 10000 to 9,999,999.
• Reserved cluster identifiers: Annex B defines reserved cluster identifiers for grouping related alerts. These must be used when applicable; otherwise use the free range defined in IEC 62923-1.
• Manufacturer documentation: Manufacturers must provide a list of all alerts included in the equipment under test (EUT) together with assigned alert and cluster identifiers.
• Verification and testing: Test methods include inspection of manufacturer documentation and, where applicable, causing sample alerts (up to 5 from Annex A and up to 10 custom alerts) to confirm reported ALF messages show correct identifiers.
• Coordination and maintenance: The standard supports coordinated allocation of identifiers across IEC/ISO/IMO standards to avoid duplicate use and to allow future additions as new equipment standards define alerts.

Practical applications and users

Who uses EN IEC 62923-2:2018

• Equipment manufacturers (navigation systems, alarms, integrated bridge systems) - to implement compliant, machine‑readable alerting and produce required documentation.
• System integrators and shipyards - to ensure consistent alert handling when integrating multiple bridge systems.
• Ship operators and ship managers - to verify equipment interoperability and support bridge alert workflows and responsibility transfer processes.
• Test labs and certification bodies - to perform compliance testing against BAM requirements.

Practical benefits

• Improved interoperability of bridge alarms across vendors.
• Clear, machine‑readable alerts to support automated responsibility transfer and alarm escalation.
• Reduced ambiguity and improved situational awareness on the bridge.

Related standards

• EN/IEC 62923-1 - Bridge alert management Part 1 (operational/performance requirements and test methods)
• IMO SOLAS and related IMO guidance (A.481(XII), MSC.128(75), FSS Code) referenced for maritime safety context

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.
International Standard IEC 62923-2 has been prepared by IEC technical committee 80:

INTRODUCTION
This document is written to support the implementation of IEC 62923-1, through the definition
of harmonized machine readable alert identifiers that can be used to facilitate the
implementation of responsibility transfer.
References are made to IEC 62923-2 in other standards. Many IEC standards involve alert
communications to which bridge alert management principles apply. This includes
interconnections between equipment to transfer alerts. Many standards define alerts for which
alert identifiers could be applied to enable machine-reading of these alerts.
It is important to coordinate the alert identifiers, to maintain machine-readability and to
prevent double use of an identifier. Due to the development of standards, it is important to
maintain this list.
This edition of the document contains the alert identifiers which have defined at the time of
publication. As bridge alert management is introduced into maritime navigation and
radiocommunication equipment, alert identifiers will be added into equipment standards. It is
intended that later editions of this document will include the alert identifiers subsequently
defined in the equipment standards.
