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, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 464, Small craft, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This first edition of ISO 23411, together with ISO 8848:2020, cancels and replaces ISO 8848:1990,
ISO 9775:1990 and ISO 15652:2003, which have been technically revised.
The main changes compared to the previous editions are as follows:
— the steering wheel requirements from ISO 8848:1990, ISO 9775:1990 and ISO 15652:2003 have
been consolidated into this document;
— the requirements have been updated to meet current industry practices.

Introduction
Previously, steering wheels were addressed in ISO 8848:1990, ISO 9775:1990 and ISO 15652:2003. A
review of the steering standards for a merge project found that updates were needed for consistency
and to meet current industry practices. This document thus provides a consistent approach for the
design and testing of steering wheels for small craft.
Steering wheel size and application was considered in the development of this document for small craft
under foreseeable operating conditions. It is recognized that high speed craft experience additional
impact loads and these are addressed in the document.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes
nationaux de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est
en général confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l'ISO participent également aux travaux.
L'ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a été
rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www
.iso .org/ directives).

La présente première édition de l’ISO 23411, conjointement à l’ISO 8848:2020, annule et remplace
l’ISO 8848:1990, l’ISO 9775:1990 et l’ISO 15652:2003, qui ont fait l'objet d'une révision technique.
Les principaux changements par rapport aux éditions précédentes sont:
— les exigences relatives aux barres à roue/volants des ISO 8848:1990, ISO 9775:1990 et ISO 15652:2003
ont été consolidées dans le présent document;
— les exigences ont été mises à jour afin de répondre aux pratiques actuelles de l'industrie.

Introduction
Les barres à roue/volants de direction étaient précédemment traitées dans l’ISO 8848:1990,
l’ISO 9775:1990 et l’ISO 15652:2003. Un examen des normes relatives aux systèmes de direction pour un
projet de fusion a révélé que des mises à jour étaient nécessaires pour assurer l'uniformité et respecter
les pratiques actuelles de l'industrie. Le présent document apporte ainsi une approche cohérente pour
la conception et les essais de barres à roue/volants pour les petits navires.
La taille et l’application des barres à roue/volants ont été prises en compte dans l'élaboration du présent
document pour les petits navires dans des conditions de fonctionnement prévisibles. Il est reconnu que
les bateaux rapides subissent des charges d'impact supplémentaires et celles-ci sont traitées dans ce
document.
