SIST EN ISO 8848:2022 PDF

Overview

EN ISO 8848:2022 - Small craft: Remote mechanical steering systems (ISO 8848:2022) specifies design, construction, installation and test requirements for remote mechanical cable steering systems and the output ram interface to rudders, jet drives, outboard and sterndrive engines on small craft. The standard is published by CEN/ISO and applies to three classes of steering systems: standard duty, light duty, and mini-jet systems. It does not cover emergency steering means, steering wheels as supplied components, hydraulic or electrical/electronic steering control systems.

Key topics and technical requirements

EN ISO 8848:2022 covers the full lifecycle of remote mechanical steering systems with emphasis on safety, interoperability and conformity:

• Scope and definitions: Terms such as craft-mounted steering system, output ram, interface point, drag link and mini-jet craft.
• Constructional requirements: Materials, mechanical design and interfaces for cables, output rams and guides.
• Engine and drive interfaces: Design considerations for outboard, sterndrive and inboard jet-drive installations.
• Steering system components:
  • Steering cables and output assemblies
  • Steering mechanisms and control elements (wheels, handlebars, joysticks)
  • Interface points between steering system and craft propulsion or rudder
• Installation: Procedures for mounting craft‑mounted steering systems and securing guide tubes and interface points.
• Testing:
  • As-installed tests verifying system performance in situ
  • Component tests for cables, mechanisms and output assemblies
  • Requirements for markings, owner’s manual and installation manual
• System classes & interchangeability:
  • Standard duty: for craft with single/twin outboards >15 kW and for rudders, sterndrives, water-jets
  • Light duty: single outboard 15–40 kW
  • Mini-jet: for inboard jet-driven craft under 1 000 kg (not PWC)
  • Note: standard and light duty systems are mechanically interchangeable; mini-jet systems are distinct.

Applications and who uses this standard

EN ISO 8848:2022 is intended for professionals involved with small craft steering systems:

• Boat designers and naval architects specifying mechanical steering for small craft
• Manufacturers of steering cables, mechanisms, output rams and steering assemblies
• Marine engineers and fitters performing installation and commissioning
• Test labs, conformity assessors and notified bodies evaluating compliance with EU requirements
• Regulatory and certification bodies relying on standards to demonstrate conformity (see Annex ZA relationship to Directive 2013/53/EU)

Related standards (if applicable)

• ISO 12217 series (stability and buoyancy assessment) - referenced for craft categorization and safety context.
• Standards covering hydraulic, electrical/electronic steering or propulsion controls are outside EN ISO 8848’s scope and should be consulted where applicable.
