This document specifies the evaluation of the fire performance of water mist systems used for local application involving flammable liquid fires. The tests specified in this document are applicable to the following: a) flammable liquid pool fires where the liquid release can be confined to a bunded area, where the entire surface of the bunded area is protected by the water mist system; b) flammable liquid channel fires in channels not exceeding the maximum specified width of the water mist system and with no limited channel length; c) partially obstructed flammable liquid pool fires where the percentage of obstructed surface is limited to that tested; d) spray fires up to 6 MW fuelled by flammable liquids; e) spray and pool fire combinations where confined to a bunded area; f) flammable liquid residues (ink and paper dust) on printing presses.

This document specifies fire testing requirements for water mist systems using wall mounted, electronically operated targeting nozzles for fire protection of domestic and residential occupancies up to a maximum ceiling height of 7,3 m. EXAMPLE Examples for residential occupancies are family dwelling/house, bed and breakfast, apartment buildings, blocks of flats, care homes, small hotels or hostels, and residential areas in hotel bedrooms and guest corridors. NOTE Some countries can have a national annex with guidance on the maximum height of the building, minimum design area and any additional requirements.

This document specifies requirements, test methods and performance criteria for factory-applied polymer coatings applied to the internal and external surfaces of steel pipes intended for use in fixed water-based fire-fighting systems designed in accordance with the EN 12845 series of standards. This document specifies requirements for the polymer coating when used as a corrosion-protection system. The mechanical and functional characteristics of the steel pipes and pipe systems are outside the scope of this document and are as specified in the EN 12845 series. NOTE Throughout this document, the term "coating" refers exclusively to factory-applied polymer coatings unless otherwise specified.
