This document specifies requirements for the design, construction and installation of sewage treatment systems on small craft. It does not address waste retention systems, nor accidental discharge prevention of pollutants (e.g. oil, fuel) overboard. It does not address the technical discharge limits of a sewage treatment unit, subject to certain international as well as national regulations.

This document establishes requirements for the design and installation of engine-mounted fuel, oil and electrical components on diesel inboard-mounted engines for minimizing fuel leakage, risk of electric shock and the risk of and/or the spread of fire on small craft of hull length up to 24 m in accordance with ISO 8666.

This document specifies design and testing requirements for steering wheels for small craft.

This document specifies design, construction, installation and test requirements for remote mechanical cable steering systems and the output ram interface point to rudders, jet drives, outboard and sterndrive engines for small craft. It is applicable to three distinct classes of steering systems for use on various types of craft: — standard duty steering systems, for small craft with single and twin installations of outboard engines with a total over 15 kW power, and with rudders, sterndrives, a...view more

This document specifies requirements for electrically operated bilge pumps intended for use in removing bilge water. It applies to: — direct current (DC) bilge pumps which operate at a nominal voltage not exceeding 50 V; and — single phase alternating current (AC) bilge pumps which operate at a nominal voltage not exceeding 250 V. It does not cover pumps intended for damage control.

This document specifies the requirements for the design, construction and installation of the following types of DC and AC electrical systems, installed on small craft either individually or in combination: a) extra-low-voltage direct current (DC) electrical systems that operate at nominal potentials of 50 V DC or less; b) single-phase alternating current (AC) systems that operate at a nominal voltage not exceeding AC 250 V. This document does not cover the following: — electrical propulsion sys...view more

This document specifies requirements for through-hull fittings, seacocks, hose connections, their fittings and their installation in small craft with a length of hull, LH, as defined in ISO 8666:2020, of up to 24 m. This document is not applicable to engine and heater exhaust fittings, and sail drive through-hull fittings.

This document specifies methods for the determination of: — the design loads and design stresses on rig elements; and — the loads and scantlings of rig attachments and mast steps/pillars; on monohull and multihulls sailing craft. It also gives, in Annexes, "established practices" for the assessment of mast steps/pillars or chainplates NOTE 1 Other engineering methods can be used provided the design loads and design stresses are used. This document is applicable to craft with a hull length LH up ...view more

This document defines the dimensions, local design pressures and global loads acting on multihull craft with a hull length (LH) or load line length of up to 24 m (see Note). It considers all parts of the craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217 (all parts). Scantlings corresponding to the local design pressures are then assessed using ISO 12215-5. NOTE The load line length is defined in the OMI "International ...view more

This document establishes definitions of main dimensions and related data and of mass specifications and loading conditions. It applies to small craft having a length of the hull (LH) of up to 24 m.

This document specifies requirements for the field of vision from the steering position, forward (horizontally and vertically) and astern, for small craft up to 24 m length of hull (LH) in accordance with ISO 8666:2016.

This document specifies technical requirements and test methods for windows, portlights, hatches, deadlights and doors on small craft with a length of hull, LH, as defined in ISO 8666:2016, of up to 24 m. It takes into account the type of craft, its design category, and the location of the appliance. The appliances considered in this document are only those that are critical for the craft's watertightness. Openings and non-opening devices fitted below area I (see 3.5.2) are excluded from the sco...view more

This document specifies watertightness, draining time and sill heights requirements for watertight and quick-draining recesses and cockpits in small craft of up to 24 m load line length (see Reference [1]). Recesses located in elevated parts of the craft are covered by this document. This document does not specify requirements for the size, the shape and the location of recesses or cockpits. It only considers draining by gravity, and not by pumping or other methods. It only considers normal oper...view more

This document describes established practices for the design, construction and installation of lightning-protection systems fitted on small craft of hull length up to 24 m.

EN-ISO 15083 specifies requirements for pumping or alternative means designed to remove normal accumulations of bilge water for small craft with a length of hull, LH, as defined in ISO 8666:2016, of up to 24 m.$0This document does not set requirements for bilge pumps or bilge-pumping systems designed for damage control.

EN-ISO 25197 establishes the requirements for the design, construction and testing of electrical/electronic steering, shift and throttle systems and dynamic positioning control systems, or combinations thereof, on small craft of up to 24 m length of hull.This document does not apply to electric trolling motors and autopilot systems on sailing craft.

This document specifies requirements for the ventilation of petrol engine and petrol tank compartments
in small craft having petrol engines for propulsion, electrical generation or mechanical power, to prevent
the accumulation of explosive gases in these compartments. Personal watercraft are not covered in this
document.
