Bibliography

This document specifies requirements, describes test methods for condensed aerosol extinguishing components and covers solely condensed aerosols. This document is not intended to indicate approval of the extinguishants listed herein by the appropriate authorities, as other extinguishants may be equally acceptable.This document is intended as a standard covering solely condensed aerosol.The condensed aerosol generator typically consists of the following main components:a)solid aerosol-forming compound;b)cooling mechanism;c)ignition device(s);d)end plate discharge outlet(s);e)housing;f)mounting bracket.This document does not cover dispersed aerosols.This document requires, as a precaution, that the room is evacuated and sealed off whenever a generator is activated. Precautions include evacuation of the proximity area, criteria for re-entering and other safeguards as stated in Clause 5 of CEN/TR 15276-2:2009.
