Overview
EN ISO 15083:2020 (ISO 15083:2020) - Small craft - Bilge-pumping systems - specifies requirements for pumping or alternative means intended to remove normal accumulations of bilge water on small craft with a hull length (LH, per ISO 8666:2016) up to 24 m. Published by CEN as the European adoption of ISO 15083:2020, this standard applies to intact-boat scenarios (spray, rain, seepage, spillage and occasional shipped water) and explicitly excludes bilge systems intended for damage-control flooding conditions.
Key topics and technical requirements
The standard defines terminology, symbols and performance expectations across these main areas:
- Scope and definitions - including terms like fully enclosed boat, design category and sailing/non-sailing distinctions.
- Type, number and location of bilge-pumping systems (Clause 5.1), with separate considerations for non-fully enclosed and fully enclosed craft.
- Capacity requirements (Clause 5.3) and a summary of system requirements (Clause 5.2).
- Design and construction requirements (Clause 6), including provisions for electrically operated pumps (referencing ISO 8849 and ISO 10133).
- Installation requirements and measures to prevent accidental discharge (new in the 2020 edition).
- Owner’s manual content (Clause 8): operator information, responsibilities and safety precautions.
- Normative references and related standards (e.g., ISO 8666, ISO 9093 series, ISO 12217, IEC 60529).
Notable updates in the 2020 edition include updated definitions, a new requirement for bilge systems on some non-fully enclosed craft, and an explicit system-design requirement to prevent accidental discharge.
Practical applications and who uses it
EN ISO 15083:2020 is essential for stakeholders involved in the design, manufacture, installation, certification and use of small craft bilge systems:
- Boat designers and naval architects (system layout and compliance)
- Boatbuilders and equipment manufacturers (product specification and testing)
- Marine electrical and plumbing installers (installation and wiring practices)
- Surveyors, classification societies and notified bodies (type-approval and conformity assessment)
- Boat owners and operators (understanding required onboard systems and owner manual content)
- Regulators and dealers ensuring compliance with EU Directive 2013/53/EU (see Annex ZA)
