Ultra Fog Successfully Completes EN 14972-17 Residential Fire Tests

Ultra Fog has successfully conducted and completed full-scale fire tests in accordance with EN 14972-17 – Test protocol for residential occupancies for automatic nozzle systems.

This achievement is an important step in ensuring our solutions align with the latest European and UK regulatory framework for water mist systems.

As part of the testing programme, we successfully tested ceiling-mounted, wall-mounted (sidewall) and our NEW Concealed Nozzles, all passing with reliable suppression performance in rooms up to 5.5 m high (approved for ceilings from 2.5 to 5.5 m).

The BS EN 14972-17:2025 (EN 14972-17) standard has been introduced as part of a broader European effort to harmonise testing protocols for water mist fire suppression systems. It replaces the previous BS 8458 standard, which was withdrawn in July 2025.

While the new protocol is largely aligned with the fire test methodology previously defined in BS 8458, it introduces several updates. One important development is the possibility to conduct fire testing for sidewall water mist nozzles, which previously could not be tested within the earlier standard.
