Abstract

The Nordtest method NT FIRE 044 (FIRE PROTECTION: Fire extinguishing media powder) describes a method for determining the characteristic extinguishing efficiency of powders against class C (gases) fires. The results of the test are used to give the powder both a class B (liquids or liquefiable solids) and C classification. The present paper describes an equivalent test method for determining the characteristic extinguishing efficiency of powders against class A (solids which form glowing embers) fires. This method can be included as an amendment to the existing Nordtest method NT FIRE 044.
