Defines tests and specifies requirements for industrial and commercial watermist systems for local applications involving flammable liquid fires.

This part of BS8489 describes tests and specifies requirements for industrial and commercial watermist systems for local applications involving flammable liquid fires. The tests specified in this part of BS8489 are applicable to the following applications: 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 watermist system; flammable liquid channel fires in channels not exceeding the watermist system manufacturer’s maximum specified width and with no limit to channel length; partially obstructed flammable liquid pool fires where the percentage of obstructed surface is limited to that tested; spray fires up to 6MW fuelled by flammable liquids; spray and pool fire combinations where confined to a bunded area; flammable liquid residues (ink and paper dust) on printing presses.
