Overview

FprEN 1866-3, titled Mobile fire extinguishers - Part 3: Additional requirements to EN 1866-1 for pressure resistance of CO2 extinguishers, is a European standard developed by CEN/TC 70. This standard focuses on the design, assembly, testing, and inspection of mobile carbon dioxide (CO2) fire extinguishers, specifically addressing the critical aspect of pressure resistance during manufacturing. It supplements the general requirements outlined in EN 1866-1 with specific provisions for CO2 extinguishers, ensuring safety and reliability under pressure-related risks.

The document applies to manufacturers and testing bodies involved in producing mobile CO2 fire extinguishers, providing guidelines to meet stringent safety criteria including pressure tolerances, material requirements, and conformity with European safety directives.

Key Topics

• Scope and Purpose: Defines pressure-related design and manufacturing rules to minimize risks in CO2 extinguisher assemblies.
• Materials: Non-metallic materials are prohibited for pressure-retaining components such as cylinder bodies, valves, and hose couplings to ensure compatibility and safety.
• Cylinder Design: Requires CE or PI marking, adherence to specified filling ratios, and proper threading for secure valve connections as per Annex B.
• Cylinder Valve Requirements: Must be CE- or PI-marked, impact-tested according to EN 849, and fitted with bursting discs compliant with ISO 6718 safety standards.
• Hose Assembly: Designed to withstand operating temperature ranges; pressure tested to at least three times the maximum allowable pressure at 20 °C and twice at operating temperature extremes.
• Assembly and Marking: Manufacturers must verify thread compatibility, apply specific torque settings, ensure traceability of pressure parts, and mark components with durable identification including manufacturer, serial number, year, tare weight, filling mass, gas type, and temperature range.
• Testing Procedures: Hydrostatic pressure tests for cylinders and valves are required before assembly; hose assemblies undergo burst pressure testing per Annex C.
• Filling Mass and Ratios: Filling tolerances in line with EN 1866-1 must be respected; common filling ratios are listed with corresponding pressure limits in Annex D.
• Safety Classification: Different extinguisher components are classified according to the Pressure Equipment Directive (PED), categorizing pressure vessels, accessories, and safety devices.

Applications

This standard is crucial for:

• Fire extinguisher manufacturers producing mobile CO2 extinguishers who must ensure their products meet European safety and pressure resistance requirements.
• Quality control and testing laboratories performing pressure and material testing to verify compliance with safety standards.
• Certification bodies overseeing CE marking and regulatory conformity in line with EU Directive 97/23/EC.
• Maintenance and inspection services requiring precise knowledge of pressure ratings, component classifications, and marking requirements to ensure safe handling and refilling.
• Safety engineers and compliance officers developing fire safety protocols for industrial, commercial, and public spaces where CO2 fire extinguishers are employed.

Adopting FprEN 1866-3 guarantees enhanced safety by controlling critical pressure-related aspects of mobile CO2 fire extinguishers, helping prevent operational failures and ensuring reliable fire-fighting performance.

Related Standards

• EN 1866-1: Mobile fire extinguishers - Part 1: Characteristics, performance requirements and test methods – The base standard providing general requirements.
• EN 1866-2: Additional requirements for extinguishers with pressures up to 30 bar.
• EN 849: Impact test standards for valves used in extinguishers.
• ISO 6718: Standards for bursting discs as safety devices under overpressure conditions.
• EN ISO 15245-1 and EN 629-1: Specifications for thread types connecting valves to gas cylinders.
• EN 10204: Inspection document standards for metallic products used in extinguisher manufacturing.
• EU Directive 97/23/EC (Pressure Equipment Directive): Regulatory framework ensuring equipment safety under pressure.

Compliance with FprEN 1866-3 and related standards ensures mobile CO2 fire extinguishers meet European safety benchmarks, maintain operational integrity, and conform to legislative directives for pressure equipment.
