General Information
Overview
EN 14972-6:2023 is a CEN European Standard that defines a fire test protocol for evaluating the firefighting performance of water mist systems protecting false floors and false ceilings. Published May 2023, the document covers automatic pendent or upright nozzles used in unlimited volume and applies to horizontal, solid, flat ceilings with false-floor/ceiling cavity heights between 300 mm and 800 mm.
Key topics and technical requirements
- Scope: Test protocol for water mist automatic nozzle systems for false ceilings and false floors (300–800 mm cavity). Tests are not applicable to other configurations outside this protocol.
- System operation: Tests require the system to operate automatically without manual intervention; up to 5 nozzles retained after testing for verification.
- Test mock-up:
- Standardized mock-up: height 800 mm, width 400 mm, length = three times nozzle spacing.
- Non-combustible ceiling and floor plates; one side open; one side plywood wall (≈5 mm).
- Fuel package and ignition:
- Cable-based fire load (specified cable types and loading); cable trays of non-combustible, open ladder type.
- Ignition source: heptane pan (200 × 200 × 20 mm) filled with 120 ml heptane, positioned beneath lower cable tray.
- Reference sprinkler baseline:
- Ordinary Hazard 1 classification, water discharge density 5.75 l/min·m², protected area per sprinkler 12 m², sprinkler K-factor 80, temperature rating 68 °C, and arrangement of two sprinklers (max 3.5 m spacing).
- Test conditions:
- Tests conducted at manufacturer-specified maximum spacing and minimum discharge conditions.
- Water flow is shut off 10 minutes after activation of the first nozzle; remaining fire is then manually extinguished and damage recorded.
- Instrumentation & reporting: Requirements for temperature, pressure, timing instrumentation and detailed test reports, including system layout and unaltered test mock-up throughout the test series.
- Normative references: EN 14972-1 (design/installation), EN 12259-1 (sprinklers), EN 12845 (sprinkler system design), EN 13501-1 (fire classification).
Applications and users
EN 14972-6 is intended for:
- Water mist system manufacturers validating nozzle performance for false floor/ceiling applications
- Testing laboratories and fire test facilities performing standardized fire tests
- Fire safety engineers, specifiers and system designers who evaluate or select suppression systems for cavities and service voids
- Authorities having jurisdiction and building owners requiring validated fire protection for raised floors and suspended ceiling cavities
