Fixed firefighting systems - Water mist systems - Part 18: Test protocol for local application involving flammable liquid fires for open nozzle systems
Abstract
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.
