EN ISO 15584:2017 - Small craft: engine-mounted fuel & electrical components
Overview
EN ISO 15584:2017 (ISO 15584:2001 endorsed) defines safety requirements for engine-mounted fuel and electrical components on inboard petrol engines fitted to small craft (hull length up to 24 m). The standard is intended to minimize fuel leakage and reduce the risk of ignition of flammable gases in the engine compartment. It excludes outboard engines and personal watercraft. The document also supports conformity with EU Directive 2013/53/EU for recreational craft (see informative Annex ZA).
Key topics & technical requirements
- Design and installation requirements for engine-mounted components (carburettors, fuel pumps, filters, piping, hoses).
- Ignition protection of electrical components capable of producing sparks (in accordance with ISO 8846).
- Fuel containment and leak prevention:
- Metallic fuel piping or fire-resistant fuel hoses that meet ISO 7840 with permanent end fittings.
- Components must withstand exposure to fire (2.5 min free-burning fuel test per ISO 10088).
- Operating temperature range: –10 °C to +80 °C; storage: –30 °C to +80 °C.
- Carburettor and throttle-body requirements:
- Backfire flame arresters per ISO 13592.
- Venting to be internal to the air-induction system unless flame-arresting.
- Pressure limits: fuel-pump pressure to carburettors not to exceed 70 kPa; carb float to resist 80 kPa; throttle bodies to resist 350 kPa.
- Mechanical robustness and corrosion resistance:
- Conditioning tests include shock/vibration cycles and a 96 h salt spray (ISO 9227).
- Installation documentation: manufacturers must provide clear installation instructions; all engine-fuel connections should be accessible for inspection and maintenance.
Practical applications & users
Who uses EN ISO 15584:2017:
- Marine engine manufacturers - to design engine-mounted fuel/electrical components compliant with safety rules.
- Boat and small craft builders - for safe integration of inboard petrol engines.
- Marine equipment designers & suppliers - to select compliant hoses, pumps, filters and ignition-protected electrical devices.
- Installers, surveyors and certification bodies - to verify conformity with EU Directive 2013/53/EU and national regulations.
Practical uses include specifying acceptable materials, testing procedures, installation layouts, and maintenance accessibility to reduce fire and leakage risks on small craft.
