Overview
EN 12094-8:2006 is a CEN European Standard for connectors used in fixed gas firefighting systems. It specifies requirements and test methods for both flexible and rigid connectors in CO2, inert gas and halocarbon gas extinguishing systems. The standard covers connectors installed between container valves and manifolds, in pneumatic pilot lines, and in distribution pipework downstream of manifold/selector valves (designated type 1–5 connectors).
Key topics and technical requirements
- Scope and connector types: Type 1 & 5 (container-to-manifold), Type 2 & 4 (distribution pipework downstream of manifold), Type 3 (pneumatic pilot lines).
- Materials and design: Metal parts shall be stainless steel, copper, copper alloy or corrosion‑protected steel; non‑metallics and elastomers must resist ageing and media contact.
- Working and bursting pressures: Connectors must be specified by the manufacturer for a minimum working pressure (see Table 1 in the standard). Typical values given include 140 bar for some CO2 high‑pressure components and 60/25 bar for distribution types; bursting pressure must be at least three times working pressure.
- Connection threads: Threads shall conform to recognized standards (e.g. ISO 7‑1 or EN ISO 228‑1).
- Type tests and performance:
- Resistance to leakage (pressure tests at 1.5× working pressure)
- Resistance to bursting (3× working pressure)
- Resistance to pressure and heat (specific tests for type 2/4, including high temperature exposure)
- Cold and heat shock, cold resistance for flexible connectors
- Flexing endurance for type 2 flexible connectors
- Documentation and marking: Manufacturers must provide technical, installation, operation and maintenance documentation; marking and conformity assessment (initial type testing and factory production control) are addressed.
- Reference test conditions: Detailed test procedures and conditions (sample preparation, acceptance criteria, test temperatures/pressures) are specified in clauses 5–7.
Applications
- Specifying and validating connectors for CO2, inert gas and halocarbon fire suppression systems in industrial, marine, data center and commercial installations.
- Ensuring compatibility and safety of distribution pipework and container/manifold interfaces.
- Supporting product certification, type approval and CE marking for connector components.
Who should use this standard
- Manufacturers of connectors and pressurized firefighting components
- Fire protection system designers and specifiers
- Certification bodies and test laboratories performing type testing
- Installers, maintenance teams and facility managers verifying component compliance
