This standard specifies fire performance evaluation procedures for water mist systems protecting wet benches and similar processing equipment with open nozzle systems.
BS EN 14972-13:2026 specifies fire performance evaluation procedures for water mist systems used to protect wet benches and other similar processing equipment. It defines test hall and enclosure requirements, wet bench mock-up configurations, instrumentation, fuel types, ignition procedures, fire test scenarios, acceptance criteria, splash testing, and test report requirements. The standard covers ventilated subsurface and working surface fire tests, including polypropylene, acetone, isopropyl alcohol, and heptane pool fires, as well as single-nozzle tests for ventilated and unventilated spaces.
Application Scope: Suitable for manufacturers, testing laboratories, fire protection engineers, system designers, certification bodies, and organizations evaluating open-nozzle water mist systems for wet benches and similar processing equipment.
