Description (English):

This document specifies the test methods for marine external firefighting systems after installation aboard, mainly including test preparation, test conditions, test apparatus and procedures. This document excludes the performance requirements of the equipment. This document is applicable to the testing of external firefighting systems installed on ships for the purpose of extinguishing fires occurring on other vessels, offshore structures or quayside structures. This document applies to marine external firefighting system with water or foam as the medium.

Abstract

Overview

ISO 24569:2023 - Ships and marine technology - External firefighting system test methods - defines standardized test methods for marine external firefighting systems after installation aboard ship. Applicable to systems using water or foam to fight fires on other vessels, offshore installations or quayside structures, the standard specifies test preparation, test conditions, required test apparatus and step‑by‑step procedures. It explicitly excludes equipment performance requirements (those remain with manufacturers or other standards).

Key topics and technical requirements

Scope and applicability: External firefighting systems installed aboard ships for external firefighting using water or foam.
Test preparation: Required documentation (system schematics, layouts, electrical diagrams, operation instructions, equipment test programme).
Instruments and accuracy: Lists measurement tools and tolerances (e.g., anemometer 0.5 m/s, stopwatch 0.1 s, thermometer 1 °C, goniometer 1°; pressure ±1 %, electrical quantities ±1.5 %).
Test conditions: System must be installed and fully operable; when measuring monitor throw wind ≤ 3 m/s and spray aligned with wind.
Electrical tests: Insulation resistance before/after tests - minimum 1 MΩ.
Mechanical/electrical operation tests:
- Electric valve operation (manual and remote), smooth movement, correct indication; measurements of operating current/voltage.
- Fire monitor operation: static (console, portable, local control; angle checks with goniometer) and dynamic (operate under rated injection pressure). Measure rotation limits and verify limit devices.
Control & alarm systems: Visual/audible indications; simulated-fault checks to verify alarms.
Fire pump tests: Start/stop function (at least three starts/stops), interlocks, emergency stop, idle/run endurance (10 min idle, 10 min normal); check for vibration, leakage, overheating; bearing shell temperature limits (
