This standard introduces a robust and comprehensive test protocol specifically developed for automatic nozzle systems used in residential occupancies. It reflects the latest understanding of fire development in modern homes and sets a new benchmark for performance.
Independent fire testing was carried out by Baltic Fire Laboratories, with results documented, confirming that Automist meets the fire performance requirements of EN 14972-17.
Transition from BS 8458 to EN 14972
The long-standing British Standard BS 8458 is currently being withdrawn and replaced by the EN 14972 series, aligning UK practice with a harmonised European framework for water mist systems.
This transition represents an evolution in testing methodology and performance criteria—not a reduction in safety requirements. The new EN 14972 standards build on the principles established in BS 8458 while introducing more detailed and scenario-based fire testing.
Continued Compliance and Assurance
The withdrawal of BS 8458 does not mean that existing or previously installed systems are non-compliant.
Automist systems:
- Were designed and tested in accordance with BS 8458
- Continue to meet regulatory and building control expectations
- Now demonstrate effective fire performance passing tests to the latest EN 14972-17 standard
This ensures continuity for specifiers, regulators and residents, while providing confidence that Automist remains at the forefront of fire protection performance.
