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.
• Installers, maintenance personnel and safety managers - to ensure correct installation, safe operation and ongoing reliability of container valve assemblies.

Related standards

• Other parts of the EN 12094 series covering gas extinguishing system components (control devices, selector valves, nozzles, gauges, etc.) and referenced standards such as EN 849 (cylinder valves), EN ISO 9001 and relevant ISO thread/pressure standards. Use EN 12094-4 alongside the broader EN 12094 family for comprehensive compliance.

4.2.3 The manufacturer shall specify the free cross-sectional area of the minimum flow way of the valve. In addition the manufacturer may specify the flow characteristics of the component either as an equivalent length or as a flow resistance coefficient. 4.2.4 The manufacturer shall specify the smallest container, the related minimum and maximum fill ratio and, if applicable, the related superpressurization the component shall be used for. 4.2.5 Where the component is assembled with a diptube, the diptube shall be made of metal, rigid or flexible, and shall be fixed to the container valve by mechanical means, e.g. a threaded connection. The geometry of the inlet of the diptube and the length of the diptube related to the container shall be specified SIST EN 12094-4:2004

5.3 Compliance A visual and measurement check shall be made to determine whether the test samples correspond to the description in the technical literature (drawings, parts lists, description of functions, operating and installation instructions). 5.4 Function 5.4.1 General NOTE This test relates to the requirements of 4.2.15 and 4.4.1. 5.4.2 Mount the container valve in the attitude specified by the manufacturer or, if not given, in the attitude where maximum force is required. Verify compliance with the requirements of 4.4.1 by one of the two following methods.  Method 1: Connect the inlet of the sample to a suitable gas supply and install a pressure measuring device at the inlet of the sample. Actuate the valve and start gas flow through the sample increasing the pressure until the valve is fully open. Decrease the pressure at the inlet of the sample to 3 bar. Check that the sample remains in its fully open position. SIST EN 12094-4:2004

For pyrotechnic powered actuators the test procedure shall be set up with data provided by the manufacturer of the pyrotechnic elements to meet the three times working pressure strength requirement. 5.7 Leakage test for valves NOTE This test relates to the requirements of 4.7. Components for non-liquefied extinguishants (e.g. Inert gases) and for liquefied extinguishants without superpressurization (e.g. CO2) shall be tested in conjunction with the smallest container for which the valve is designed. The container sample shall be charged to the maximum specified fill ratio. Components for liquefied extinguishants with superpressurization shall be tested in conjunction with the smallest container for which the valve is designed. One of the specified container samples shall be charged to the minimum fill ratio and the other to the maximum fill ratio. Both containers shall be superpressurized to the superpressurization pressure. Measure and record the charge mass to an accuracy of ± 0,1 %. For superpressurized liquefied extinguishants additionally measure and record the charge pressure to an accuracy of ± 0,1 %. Expose the assembly to changes of temperature in air: a) lower temperature shall be (- 20 20-) °C, or the manufacturer's recommended minimum service temperature (02−) °C, whichever is the lower; b) higher temperature shall be (5002+) °C, or the manufacturer's recommended maximum service temperature (02+) °C, whichever is the higher; SIST EN 12094-4:2004

manufacturer (02+) °C whichever is the higher, for (2 ± 0,5) h. Carry out five test cycles as described in 5.4.3 a) to d) at test temperature. 5.10 Flow characteristics 5.10.1 General NOTE This test relates to the requirements of 4.9.
