Overview
EN 12094-4:2004 is a CEN European standard for fixed firefighting systems that defines requirements and test methods for container valve assemblies and their actuators used in gas extinguishing systems. It covers assemblies for CO2 (high-pressure), Inert Gas and Halocarbon Gas fire suppression installations. The standard applies to a complete container valve assembly (container valve, actuator and, where fitted, diptube) and addresses only features relevant to fire extinguishing installations. Diptubes supplied separately (not assembled to valves) are excluded.
Key topics and technical requirements
- Scope and definitions: classification of valve types (e.g., valves with or without pressure relief) and terminology specific to gas extinguishing components (CO2 high/low pressure, Inert Gas, Halocarbon Gas, diptube, fill ratio).
- Design and materials: metallic valve bodies and internal parts; corrosion-resistant materials (stainless steel, copper, copper alloys or protected steel) for durability in fire protection applications.
- Working pressure: components must be specified by the manufacturer for appropriate working pressures (example: CO2 high-pressure container valves tested at 140 bar).
- Performance requirements: functional operation across ambient/operational temperatures, flow characteristics and resistance coefficients, specified minimum flow area.
- Safety features: pressure relief device classifications and warnings about release into protected zones.
- Mechanical integrity: strength, resistance to internal pressure, leakage limits, vibration resistance, stress-corrosion considerations.
- Operational reliability: actuator performance (manual, pneumatic, etc.), operating force, functional testing and lifecycle checks.
- Diptube requirements: material, attachment method, geometry and installation orientation details when supplied as part of the assembly.
- Testing methods: prescribed tests for function, internal pressure, strength, leakage, flow characteristics, corrosion, vibration, temperature and operational reliability (see clauses 5.x).
- Marking, documentation and conformity: manufacturer data, marking, initial type testing, factory production control and conformity evaluation procedures.
Applications and who uses this standard
- Manufacturers of container valve assemblies, actuators and diptubes - use EN 12094-4 to design, test and declare conformity of components for gas extinguishing systems.
- System designers and specifying engineers for CO2, Inert Gas and Halocarbon gas fire suppression installations - to select compliant components and verify performance.
- Testing laboratories and certification bodies - to perform type testing, factory production control and conformity assessment.

The EN 12094-4:2004 standard provides a comprehensive framework for assessing and ensuring the safety and efficacy of container valve assemblies utilized in fixed firefighting systems, specifically those that utilize carbon dioxide (CO2), inert gases, and halocarbon gases. This document is critical as it details both the requirements and test methods necessary for validating the functionality and reliability of these essential components within fire extinguishing installations. One of the significant strengths of this standard is its specificity; it focuses solely on the elements directly related to the operation of container valve assemblies, which consist of the valve itself, the actuator, and potential diptubes. This targeted approach ensures that manufacturers and users can clearly understand what is necessary for compliance and performance excellence. By outlining the relevant performance features, the standard aids in mitigating risks associated with fire hazards, making it a vital reference for the industry. Moreover, EN 12094-4:2004's provision for additional components like gauges and switches reflects its adaptability and relevance in modern firefighting technology. This inclusion allows for a comprehensive evaluation of the valve assembly's operational parameters, ensuring that each component works in harmony to enhance the overall effectiveness of the fixed firefighting systems. The focus on testing methods within the standard is particularly noteworthy, as these protocols not only establish a benchmark for quality but also promote consistency in manufacturing practices. This is essential in maintaining safety standards across different jurisdictions and applications, reinforcing the document's value to stakeholders in the firefighting sector. In summary, the EN 12094-4:2004 standard is an essential tool for the industry, providing clear requirements and robust test methodologies that contribute to the reliability and safety of container valve assemblies in fixed firefighting systems. Its relevance in an increasingly safety-conscious environment cannot be overstated, as it helps ensure that fire extinguishing systems perform optimally when required.
