General Information
Relations
Overview
EN ISO 25197:2020 (ISO 25197:2020) specifies requirements for the design, construction and testing of electrical/electronic control systems for steering, shift and throttle - and for dynamic positioning systems (DPS) - on small craft up to 24 m hull length. Published by CEN and adopted as a European Standard, it supersedes EN ISO 25197:2018. The standard does not cover electric trolling motors or autopilot systems on sailing craft.
Key topics and technical requirements
EN ISO 25197:2020 addresses functional design, safety and verification across hardware, software and system integration aspects. Major topics include:
- General requirements for system architecture, interfaces and documentation
- Control head and command station transfer requirements (control ergonomics and signal handling)
- Portable helm station controls and remote input/output device definitions
- Control devices: separate/combined shift and throttle levers, joystick control modes
- Dynamic-positioning systems (DPS) and related control logic
- Failure modes and responses, including loss of operation and loss of computer command logic
- Comprehensive test requirements:
- Environmental testing (salt mist, damp heat cyclic/steady, high/low temperature storage and operation)
- Vibration, shock and drop testing
- UV resistance
- Electromagnetic compatibility (EMC) - emissions and immunity (radiated/conducted, ESD, surge, bursts, power variations)
- Compass safe distance and insulation resistance
- Labelling and owner’s manual information requirements (noting clauses that support EU Directive 2013/53/EU conformity)
Practical applications and who uses it
EN ISO 25197:2020 is intended for manufacturers, designers and integrators of small craft control systems as well as test laboratories, type-approval bodies and regulatory authorities. Typical use cases:
- Development and certification of electronic steering systems, throttle/shift control assemblies and joystick manoeuvring for RIBs, patrol boats, workboats and recreational craft up to 24 m
- Design and verification of DPS for station-keeping on small commercial or special-purpose craft
- Preparing compliant owner’s manuals, labels and documentation to support CE marking and EU Directive conformity
- Test houses executing environmental, mechanical and EMC test protocols required for product acceptance

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 25197:2012), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— the terms and definitions have been revised to give coherency with other standard definitions; new
terms, such as input device and output device, have been introduced;
— the figures have been revised to clarify the concepts illustrated;
— 7.2, on portable helms, has been revised to make it coherent when an electric propulsion motor is used;
— 9.1 has been revised to include the fail-safe mode and the alarm policy;
— the main change is in 10.1: the request to use three different samples for all tests (except for EMC
test) has been deleted because it would have involved a great expense without having significant
improvement; only one sample is used for all tests described on the subsequent subclauses;
— the durability test on joystick described in 10.4 has been made an operational test;
— Table 1 in 10.5.1 has been updated introducing the column “immersion” to handle test on immerged
components;
— in 10.5.2, all ways to conduct the salt mist test, based on different standards, have been homogenized;
— in 10.7, the shock test has been revised;
— in 10.8, the free fall test has become the drop test with the addiction of the UV test;
— the UV test, described in 10.9, has been clarified;

ISO 25197:2020(E)
— in 10.10, there are many changes due to the revision of IEC 60533 and the forthcoming release of
IEC 62742; to avoid any direct link to those standards, all tests previously required by IEC 60533
have been embedded and all standards cited have been added to the normative reference list.
