Описание (английский):

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.

Overview

EN ISO 8849:2021 (identical to ISO 8849:2020) specifies requirements for electrically operated bilge pumps for small craft. The standard applies to:

DC bilge pumps with nominal voltage ≤ 50 V, and

Single‑phase AC bilge pumps with nominal voltage ≤ 250 V.

It is focused on pumps intended to remove bilge water and explicitly does not cover pumps intended for damage control. The third edition updated the scope and added a clause on the owner’s manual.

Key topics and technical requirements

The standard defines functional, electrical and safety requirements that manufacturers, installers and inspectors should follow:

Performance ratings: Pumps must be rated in litres per minute/hour at nominal voltage for static heads of 0 m, 1 m and 2 m (0, 10 kPa, 20 kPa). Ratings and maximum output lift must appear in the instructions.

Continuous operation: Pumps shall operate continuously for 24 h at 87.5% of nominal voltage within recommended performance ranges.

Dry‑run capability / fire safety:

Centrifugal and axial flow pumps: capable of dry operation for at least 7 h at design voltage without creating a fire hazard, or provide automatic shut‑off.
Positive/semi‑positive displacement pumps: withstand 5 min dry operation without damage and 1 h without fire hazard; owner’s manual must warn against >1 min dry running, or provide automatic shut‑off.

Materials and corrosion resistance: Components in contact with seawater must be corrosion‑resistant, galvanically compatible and resistant to petrol, oil, diesel and bilge cleaners.

Submersible pumps: Require inlet strainers or cleanable screens and watertight electrical connections (IP67) per IEC 60529; use of sealed cable sections to keep final connections above critical bilge level is recommended.

Electrical safety & marking:

Compliance with ignition protection (ISO 8846) where explosive vapours may accumulate.
Electrical requirements and installation guidance per ISO 13297.
Pumps must include installation/operating instructions, wiring diagrams, recommended overcurrent protection and secure mounting means.

Documentation: Clause 7 requires a user/operator manual and clear markings.

Applications and users

EN ISO 8849:2021 is used by:

Bilge pump manufacturers for design, testing and product documentation.

Boat builders and marine electricians for correct installation and selection.

Surveyors, certifiers and regulatory bodies assessing conformity with marine safety rules and Directive 2013/53/EU (see Annex ZA).

Boat owners and fleet managers to understand performance, safe operation and maintenance.
