This G-4 aft galley was chosen by the Pyrogen test team to simulate a high BTU electrical cabin fire. Galleys are a major contributor to smoke and electrical fires in commercial aircraft. An identical galley was removed form another aircraft for this series.  The galley was then modified with a viewing window and the inner dividers removed. 128 Wires were placed in the lower section over a 400 mm fuel cup. Located away from the Pyrogen discharge path, the wire was pre burned for 1 minute and the aerosol used to extinguish the fire. Several additional smaller (25 mm) fuel cups were placed at different levels inside the galley. After the pre burn the doors were closed and the agent dispensed into the enclosure. Fuel cup and wire bundle temperatures were monitored and recorded with type K thermal couples Electrical wire temperature exceeded 200 deg C prior to discharge, with no reignition of the fuel cups was observed.
