Overview

EN ISO 10592:2022 - Small craft: Remote hydraulic steering systems (ISO 10592:2022) specifies requirements for the design, installation and testing of remote hydraulic steering systems used on small craft. It covers engine‑mounted and craft‑mounted systems for single and multiple engine installations of outboard engines over 15 kW per engine, and for single and multiple inboard, sterndrive and water‑jet drives. The standard addresses components from the helm (hydraulic helm) through the output device connection point. It does not cover emergency means of steering.

Key topics and technical requirements

• Scope and applicability: Engine-mounted and craft-mounted remote hydraulic steering systems on small craft; excludes steering wheels supplied as separate components and emergency steering.
• Design requirements: Definitions and interfaces (hydraulic and mechanical), component proof pressure and component maximum working pressure (defined in the standard), and guidance on materials and mechanical interfaces.
• Installation: Mounting and routing of hydraulic lines, component interfaces, and requirements for outboard engines, sterndrives and inboard drives to ensure reliable operation and serviceability.
• Testing and verification: Installed proof tests, system application tests and steering‑system component tests are specified. The standard defines performance measures such as minimum retained system performance (≥90% of steering arm travel attainable with ≤27 Nm helm torque) and addresses burst pressure and pressure ratings.
• Documentation: Requirements for an Owner’s manual and Installation manual to accompany steering systems, supporting safe use and correct installation.
• Updates and alignment: This edition (2022) replaces earlier editions and removes steering wheel requirements to reflect state‑of‑the‑art hydraulic steering technology.

Practical applications and users

EN ISO 10592:2022 is used to ensure safe, reliable remote hydraulic steering on small craft. Typical users include:

• Boat and outboard/sterndrive manufacturers specifying steering systems for new craft
• Steering system and hydraulic component manufacturers (helms, cylinders, fittings)
• Naval architects and marine engineers designing propulsion and steering arrangements
• Marine installers and service technicians performing installation, testing and commissioning
• Certification bodies and notified bodies assessing conformity with EU requirements (see Annex ZA)
• Owners and fleet managers relying on Owner’s and Installation manuals for maintenance and safe operation

Keywords: EN ISO 10592:2022, remote hydraulic steering systems, small craft steering, hydraulic helm, steering system testing, outboard engines >15 kW.

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).
